In cultured pearls, the irritant is typically an introduced piece of the mantle epithelium, with or without a spherical bead beaded or beadless cultured pearls.
It is thought that natural pearls form under a set of accidental conditions when a microscopic intruder or parasite enters a bivalve mollusk and settles inside the shell.
The mollusk, irritated by the intruder, forms a pearl sac of external mantle tissue cells and secretes the calcium carbonate and conchiolin to cover the irritant.
This secretion process is repeated many times, thus producing a pearl. Natural pearls come in many shapes, with perfectly round ones being comparatively rare.
Typically, the build-up of a natural pearl consists of a brown central zone formed by columnar calcium carbonate usually calcite, sometimes columnar aragonite and a yellowish to white outer zone consisting of nacre tabular aragonite.
In a pearl cross-section such as the diagram, these two different materials can be seen. The presence of columnar calcium carbonate rich in organic material indicates juvenile mantle tissue that formed during the early stage of pearl development.
Displaced living cells with a well-defined task may continue to perform their function in their new location, often resulting in a cyst.
Such displacement may occur via an injury. The fragile rim of the shell is exposed and is prone to damage and injury. Crabs, other predators and parasites such as worm larvae may produce traumatic attacks and cause injuries in which some external mantle tissue cells are disconnected from their layer.
Embedded in the conjunctive tissue of the mantle, these cells may survive and form a small pocket in which they continue to secrete calcium carbonate, their natural product.
The pocket is called a pearl sac, and grows with time by cell division. The juvenile mantle tissue cells, according to their stage of growth, secrete columnar calcium carbonate from pearl sac's inner surface.
In time, the pearl sac's external mantle cells proceed to the formation of tabular aragonite. When the transition to nacre secretion occurs, the brown pebble becomes covered with a nacreous coating.
During this process, the pearl sac seems to travel into the shell; however, the sac actually stays in its original relative position the mantle tissue while the shell itself grows.
After a couple of years, a pearl forms and the shell may be found by a lucky pearl fisher. Cultured pearls are the response of the shell to a tissue implant.
A tiny piece of mantle tissue called a graft from a donor shell is transplanted into a recipient shell, causing a pearl sac to form into which the tissue precipitates calcium carbonate.
There are a number of methods for producing cultured pearls: using freshwater or seawater shells, transplanting the graft into the mantle or into the gonad, and adding a spherical bead as a nucleus.
Most saltwater cultured pearls are grown with beads. Most beadless cultured pearls are mantle-grown in freshwater shells in China, and are known as freshwater cultured pearls.
Cultured pearls can be distinguished from natural pearls by X-ray examination. After a bead is inserted into the oyster, it secretes a few layers of nacre around the bead; the resulting cultured pearl can then be harvested in as few as twelve to eighteen months.
When a cultured pearl with a bead nucleus is X-rayed, it reveals a different structure to that of a natural pearl see diagram.
A beaded cultured pearl shows a solid center with no concentric growth rings, whereas a natural pearl shows a series of concentric growth rings. A beadless cultured pearl whether of freshwater or saltwater origin may show growth rings, but also a complex central cavity, witness of the first precipitation of the young pearl sac.
Some imitation pearls also called shell pearls are simply made of mother-of-pearl , coral or conch shell, while others are made from glass and are coated with a solution containing fish scales called essence d'Orient.
Although imitation pearls look the part, they do not have the same weight or smoothness as real pearls, and their luster will also dim greatly.
A well-equipped gem testing laboratory can distinguish natural pearls from cultured pearls by using gemological X-ray equipment to examine the center of a pearl.
With X-rays it is possible to see the growth rings of the pearl, where the layers of calcium carbonate are separated by thin layers of conchiolin.
The differentiation of natural pearls from non-beaded cultured pearls can be very difficult without the use of this X-ray technique.
Natural and cultured pearls can be distinguished from imitation pearls using a microscope. Another method of testing for imitations is to rub two pearls against each other.
Imitation pearls are completely smooth, but natural and cultured pearls are composed of nacre platelets, making both feel slightly gritty. Fine quality natural pearls are very rare jewels.
Their values are determined similarly to those of other precious gems, according to size, shape, color, quality of surface, orient and luster.
Single natural pearls are often sold as collectors' items, or set as centerpieces in unique jewelry. Very few matched strands of natural pearls exist, and those that do often sell for hundreds of thousands of dollars.
The introduction and advance of the cultured pearl hit the pearl industry hard. Pearl dealers publicly disputed the authenticity of these new cultured products, and left many consumers uneasy and confused about their much lower prices.
Essentially, the controversy damaged the images of both natural and cultured pearls. By the s, when a significant number of women in developed countries could afford their own cultured pearl necklace, natural pearls were reduced to a small, exclusive niche in the pearl industry.
Previously, natural pearls were found in many parts of the world. Present day natural pearling is confined mostly to seas off Bahrain.
Australia also has one of the world's last remaining fleets of pearl diving ships. Australian pearl divers dive for south sea pearl oysters to be used in the cultured south sea pearl industry.
The catch of pearl oysters is similar to the numbers of oysters taken during the natural pearl days.
Hence significant numbers of natural pearls are still found in the Australian Indian Ocean waters from wild oysters. X-ray examination is required to positively verify natural pearls found today.
Keshi pearls , although they often occur by chance, are not considered natural. They are a byproduct of the culturing process, and hence do not happen without human intervention.
They are quite small, typically only a few millimeters. Keshi pearls are produced by many different types of marine mollusks and freshwater mussels in China.
Keshi pearls are actually a mistake in the cultured pearl seeding process. In seeding the cultured pearl, a piece of mantle muscle from a sacrificed oyster is placed with a bead of mother of pearl within the oyster.
If the piece of mantle should slip off the bead, a pearl forms of baroque shape about the mantle piece which is entirely nacre. Therefore, a Keshi pearl could be considered superior to cultured pearls with a mother of pearl bead center.
In the cultured pearl industry, the resources used to create a mistaken all nacre baroque pearl is a drain on the production of round cultured pearls.
Therefore, they are trying to improve culturing technique so that keshi pearls do not occur. All nacre pearls may one day be limited to natural found pearls.
Tahitian pearls , frequently referred to as black pearls,  are highly valued because of their rarity; the culturing process for them dictates a smaller volume output and they can never be mass-produced because, in common with most sea pearls, the oyster can only be nucleated with one pearl at a time, while freshwater mussels are capable of multiple pearl implants.
Before the days of cultured pearls, black pearls were rare and highly valued for the simple reason that white pearl oysters rarely produced naturally black pearls, and black pearl oysters rarely produced any natural pearls at all.
Since the development of pearl culture technology, the black pearl oysters Pinctada margaritifera found in Tahiti and many other Pacific islands including the Cook Islands and Fiji are being extensively used for producing cultured pearls.
The rarity of the black cultured pearl is now a "comparative" issue. The black cultured pearl is rare when compared to Chinese freshwater cultured pearls, and Japanese and Chinese akoya cultured pearls, and is more valuable than these pearls.
However, it is more abundant than the South Sea pearl, which is more valuable than the black cultured pearl. This is simply because the black pearl oyster Pinctada margaritifera is far more abundant than the elusive, rare, and larger south sea pearl oyster Pinctada maxima , which cannot be found in lagoons, but which must be dived for in a rare number of deep ocean habitats or grown in hatcheries.
Black pearls are very rarely black: they are usually shades of green, purple, aubergine, blue, grey, silver or peacock a mix of several shades, like a peacock's feather.
In the absence of an official definition for the pearl from the black oyster, these pearls are usually referred to as "black pearls".
A farm in the Gulf of California , Mexico, is culturing pearls from the black lipped Pinctada mazatlanica oysters and the rainbow lipped Pteria sterna oysters.
Biologically speaking, under the right set of circumstances, almost any shelled mollusk can produce some kind of pearl.
However, most of these molluskan pearls have no luster or iridescence. The great majority of mollusk species produce pearls which are not attractive, and are sometimes not even very durable, such that they usually have no value at all, except perhaps to a scientist or collector, or as a curiosity.
These objects used to be referred to as "calcareous concretions" by some gemologists, even though a malacologist would still consider them to be pearls.
Valueless pearls of this type are sometimes found in edible mussels , edible oysters , escargot snails, and so on. The GIA and CIBJO now simply use the term 'pearl' or, where appropriate, the more descriptive term 'non-nacreous pearl' when referring to such items   and, under Federal Trade Commission rules, various mollusk pearls may be referred to as 'pearls', without qualification.
A few species produce pearls that can be of interest as gemstones. These species include the bailer shell Melo , the giant clam Tridacna , various scallop species, Pen shells Pinna , and the Haliotis iris species of abalone.
Pearls of abalone, or paua , are mabe pearls, or blister pearls, unique to New Zealand waters and are commonly referred to as 'blue pearls'.
They are admired for their incredible luster and naturally bright vibrant colors that are often compared to opal. Another example is the conch pearl sometimes referred to simply as the 'pink pearl' , which is found very rarely growing between the mantle and the shell of the queen conch or pink conch, Strombus gigas , a large sea snail or marine gastropod from the Caribbean Sea.
These pearls, which are often pink in color, are a by-product of the conch fishing industry, and the best of them display a shimmering optical effect related to chatoyance known as 'flame structure'.
Somewhat similar gastropod pearls, this time more orange in hue, are again very rarely found in the horse conch Triplofusus papillosus.
The second largest pearl known was found in the Philippines in and is known as the Pearl of Lao Tzu. It is a naturally occurring, non-nacreous, calcareous concretion pearl from a giant clam.
Because it did not grow in a pearl oyster it is not pearly; instead the surface is glossy like porcelain. The largest known pearl also from a giant clam is the Pearl of Puerto , also found in the Philippines by a fisherman from Puerto Princesa , Palawan Island.
The ancient chronicle Mahavamsa mentions the thriving pearl industry in the port of Oruwella in the Gulf of Mannar in Sri Lanka.
It also records that eight varieties of pearls accompanied Prince Vijaya 's embassy to the Pandyan king as well as king Devanampiya Tissa 's embassy to Emperor Ashoka.
For thousands of years, seawater pearls were retrieved by divers in the Indian Ocean in areas such as the Persian Gulf , the Red Sea and the Gulf of Mannar.
Margarita pearls are extremely difficult to find today and are known for their unique yellowish color.
Before the beginning of the 20th century, pearl hunting was the most common way of harvesting pearls. Divers manually pulled oysters from ocean floors and river bottoms and checked them individually for pearls.
Not all mussels and oysters produce pearls. In a haul of three tons, only three or four oysters will produce perfect pearls.
Pearls were one of the attractions which drew Julius Caesar to Britain. Pearling was banned in the U.
Today, the cultured pearls on the market can be divided into two categories. The first category covers the beaded cultured pearls, including akoya, South Sea and Tahiti.
These pearls are gonad grown, and usually one pearl is grown at a time. This limits the number of pearls at a harvest period. The pearls are usually harvested after one year for akoya, 2—4 years for Tahitian and South Sea, and 2—7 years for freshwater.
This perliculture process was first developed by the British biologist William Saville-Kent who passed the information along to Tatsuhei Mise and Tokichi Nishikawa from Japan.
The second category includes the non-beaded freshwater cultured pearls, like the Biwa or Chinese pearls. As they grow in the mantle, where on each wing up to 25 grafts can be implanted, these pearls are much more frequent and saturate the market completely.
An impressive improvement in quality has taken place over ten years when the former rice-grain-shaped pebbles are compared with the near round pearls of today.
Later, large near perfect round bead nucleated pearls up to 15mm in diameter have been produced with metallic luster.
The nucleus bead in a beaded cultured pearl is generally a polished sphere made from freshwater mussel shell. Along with a small piece of mantle tissue from another mollusk donor shell to serve as a catalyst for the pearl sac, it is surgically implanted into the gonad reproductive organ of a saltwater mollusk.
In freshwater perliculture, only the piece of tissue is used in most cases, and is inserted into the fleshy mantle of the host mussel.
South Sea and Tahitian pearl oysters, also known as Pinctada maxima and Pinctada margaritifera , which survive the subsequent surgery to remove the finished pearl, are often implanted with a new, larger beads as part of the same procedure and then returned to the water for another 2—3 years of growth.
Despite the common misperception, Mikimoto did not discover the process of pearl culture. Nishikawa was granted the patent in , and married the daughter of Mikimoto.
Mikimoto was able to use Nishikawa's technology. After the patent was granted in , the technology was immediately commercially applied to akoya pearl oysters in Japan in Mise's brother was the first to produce a commercial crop of pearls in the akoya oyster.
Mitsubishi's Baron Iwasaki immediately applied the technology to the south sea pearl oyster in in the Philippines, and later in Buton, and Palau.
Today, a hybrid mollusk is used in both Japan and China in the production of akoya pearls. Cultured Pearls were sold in cans for the export market.
These were packed in Japan by the I. Mitsubishi commenced pearl culture with the South Sea pearl oyster in , as soon as the technology patent was commercialized.
By this project was showing signs of success, but was upset by the death of Tatsuhei Mise. Although the project was recommenced after Tatsuhei's death, the project was discontinued at the beginning of WWII before significant productions of pearls were achieved.
Japanese companies were involved in all projects using technicians from the original Mitsubishi South Sea pre-war projects.
Kuri Bay is now the location of one of the largest and most well-known pearl farms owned by Paspaley , the biggest producer of South Sea pearls in the world.
In , China overtook Japan in akoya pearl production. These pearls are then processed often simply matched and sorted , relabeled as product of Japan, and exported.
In the past two decades, cultured pearls have been produced using larger oysters in the south Pacific and Indian Ocean.
The largest pearl oyster is the Pinctada maxima , which is roughly the size of a dinner plate. South Sea pearls are characterized by their large size and warm luster.
In , pearl farmers began growing cultured freshwater pearls using the pearl mussels native to Lake Biwa. This lake, the largest and most ancient in Japan, lies near the city of Kyoto.
The extensive and successful use of the Biwa Pearl Mussel is reflected in the name Biwa pearls , a phrase which was at one time nearly synonymous with freshwater pearls in general.
Since the time of peak production in , when Biwa pearl farmers produced six tons of cultured pearls, pollution has caused the virtual extinction of the industry.
Japanese pearl farmers recently [ when? This industry has also nearly ceased production, due to pollution. Currently, the Belpearl company based out of Kobe, Japan continues to purchase the remaining Kasumiga-ura pearls.
Japanese pearl producers also invested in producing cultured pearls with freshwater mussels in the region of Shanghai , China.
China has since become the world's largest producer of freshwater pearls, producing more than 1, metric tons per year in addition to metric measurements, Japanese units of measurement such as the kan and momme are sometimes encountered in the pearl industry.
Led by pearl pioneer John Latendresse and his wife Chessy, the United States began farming cultured freshwater pearls in the mids.
National Geographic magazine introduced the American cultured pearl as a commercial product in their August issue. The Tennessee pearl farm has emerged as a tourist destination in recent years, but commercial production of freshwater pearls has ceased.
For many cultured pearl dealers and wholesalers, the preferred weight measure used for loose pearls and pearl strands is the momme.
Momme is a weight measure used by the Japanese for centuries. Today, momme weight is still the standard unit of measure used by most pearl dealers to communicate with pearl producers and wholesalers.
Reluctant to give up tradition, the Japanese government formalized the kan measure in as being exactly 3. In the United States, during the 19th and 20th centuries, through trade with Japan in silk cloth the momme became a unit indicating the quality of silk cloth.
Though millimeter size range is typically the first factor in determining a cultured pearl necklace's value, the momme weight of pearl necklace will allow the buyer to quickly determine if the necklace is properly proportioned.
This is especially true when comparing the larger south sea and Tahitian pearl necklaces. The value of the pearls in jewelry is determined by a combination of the luster, color, size, lack of surface flaw and symmetry that are appropriate for the type of pearl under consideration.
Among those attributes, luster is the most important differentiator of pearl quality according to jewelers. All factors being equal, however, the larger the pearl the more valuable it is.
Large, perfectly round pearls are rare and highly valued. Teardrop-shaped pearls are often used in pendants. Queen of Italy, Margherita of Savoy , owned one of the most famous collections of natural pearls.
She is wearing a multi-strand choker and a rope of pearls. Muslim "Pearl Trader" painting on mica in India.
Pearls come in eight basic shapes: round, semi-round, button, drop, pear, oval, baroque, circled and double bouldered.
Perfectly round pearls are the rarest and most valuable shape. Semi-rounds are also used in necklaces or in pieces where the shape of the pearl can be disguised to look like it is a perfectly round pearl.
Button pearls are like a slightly flattened round pearl and can also make a necklace, but are more often used in single pendants or earrings where the back half of the pearl is covered, making it look like a larger, rounder pearl.
Drop and pear shaped pearls are sometimes referred to as teardrop pearls and are most often seen in earrings, pendants, or as a center pearl in a necklace.
Baroque pearls have a different appeal; they are often highly irregular with unique and interesting shapes. They are also commonly seen in necklaces.
Circled pearls are characterized by concentric ridges, or rings, around the body of the pearl. In general, cultured pearls are less valuable than natural pearls, whereas imitation pearls have almost no value.
One way that jewelers can determine whether a pearl is cultured or natural is to have a gemlab perform an X-ray examination of the pearl.
It appears that the pearl is blinking at you as the thin patch reveals the bead underneath. For Akoya pearls, a nacre thickness of under 0.
Tahitian pearls need thicker nacre of at least 0. The minimum thickness of South Sea pearls is generally considered to be 1mm and can be as generous as 5mm thick.
Matching is a reflection on the whole piece, rather than the individual pearls. For example, if a string of intentionally matched pearls had one, slightly smaller pearl, that pearl will reduce the value of the whole string and so it would be worth replacing it.
This is an extreme case but it highlights how important matching can be. Natural and Cultured pearls are both real pearls, grown by the same animals.
The difference is that pearl farmers have initiated the process of forming a Cultured Pearl, whereas Natural Pearls started growing by chance in the wild.
Pearls are our oldest known gem. However, until about one hundred years ago we only had natural pearls because no-one knew how to recreate the miracle that is the birth of a pearl.
For literally thousands of years, pearls have been loved and cherished for their beauty and their mystery.
They were so rare that they were incredibly expensive and so could only be enjoyed by a very small group of lucky people, i. Therefore, it would take around 50, oysters to make a necklace.
Before the s, when we learned how to grow pearls, all pearls were what we now call natural, which means that they were found in an oyster picked from the wild.
Natural pearls are those that are formed when an intruder such as a bit of coral for example randomly gets stuck in a mollusc.
By the late s pearl growing oysters and mussels were running out. Nacreous i. Oil wells also began popping up at about this time which inevitably leaked, resulting in oil wiping out enormous, ancient oyster beds in many seas around the Middle East.
So with the pollution and advanced diving techniques our heroic pearl growing oysters were soon to become a thing of the past. Until, that is, we learned how to farm them creating what is known as a Cultured Pearl.
Cultured pearls are those that are formed when an intruder such as a mother of pearl bead is placed into a mollusc, i. A number of people contributed to the invention of pearl culturing and to them we are eternally grateful.
The first cultured pearl was produced by an Englishman in Australia called William Saville-Kent but it was in Japan that this revolutionary development really took hold.
A saltwater mollusc was successfully nucleated to produce an Akoya pearl and since then the pearl world has never looked back.
Natural pearl diving is now banned or at least strictly controlled in pretty much every country in the world, from Scotland to Australia.
This is to protect the incredibly valuable oyster beds. As a result of this, natural pearls have become extremely rare and are now only really traded as antiques.
They demand huge price tags and are sold in auction houses rather than jewellers. The vast majority of pearls worn today are cultured pearls.
Each species of plant grows different flowers, in a similar way different species of mollusc grow different pearls. This variation gives a huge choice of size, colour, shape, shine and price to choose from.
There are different types of oysters and mussels and each produces a different type of pearl with its own characteristics dependent upon those of the mollusc.
For example, the larger molluscs produce larger pearls and oysters with blue shells produce blue pearls. Of the 50, types of mollusc in the world, only four are used to farm pearls, producing the four major pearl types — Akoya, South Sea and Tahitian pearls which grow in the sea and Freshwater pearls that grown in lakes and rivers.
Each pearl type varies in a number of characteristics from size and colour, to lustre, shape and culturing method. Natural Freshwater pearls have been around for thousands of years but cultured Freshwater pearls only came onto the market in the s.
The first Freshwater cultured pearls were small, rice shaped, baroque pearls with poor lustre. Rather than growing in the sea like the other pearl types, Freshwater mussels grow in lakes, rivers, ponds and reservoirs, hence their name.
One of the best things about Freshwater pearls is their price. Freshwater pearls are so much easier to grow than Saltwater pearls and are therefore much more affordable.
This means that from nucleated Freshwater mussels, a farmer can expect 3, to 4, pearls. But from saltwater oysters a farmer would be lucky to yield 30 pearls.
Which is a massive difference! To nucleate a saltwater pearl the farmer will implant a bead, and a small square of soft tissue from a donor oyster.
This soft tissue then grows around the bead and lays nacre onto it, forming a pearl. A good sized Freshwater pearl is about 7mm in diameter, but they can be farmed in sizes from as small as 1mm all the way up to 12mm on a regular basis.
Freshwater pearls are farmed in some African countries and India as well as the Mississippi and Japan to a very small degree but the majority and the best quality Freshwater pearls are grown in South Eastern China, which is where we source ours.
Akoya pearls are the original cultured pearl, when we imagine pearls the first thing that springs to mind tends to be a string of beautiful, shiny, white, small, round gems, which is a fair description of Akoya pearls.
The method we use for culturing pearls today was invented by a Englishman, called William Saville-Kent, in Australia at the end of the 19th century but it was in Japan at the beginning of the 20th century that the first pearl farms began to produce commercial quantities of pearls.
The native pearl growing oyster to Japan is the saltwater Pinctada fucata which produces Akoya pearls and so when the cultured pearl revolution took off it was with Akoya pearls.
Firstly, Akoya pearls are born in a beautiful array of white, blue, grey and yellow hues. Akoya pearls are the most frequently round of all pearl types and all else being equal, the rounder a pearl, the more expensive it will be.
Tahitian pearls are just wonderful; they shine in the most incredible combination of colours from peacock to pistachio, green to silver, orange, blue, yellow and everything in between.
They grow in the huge black lipped oyster that you can see above. They can be about a foot 30cm across, which allows us to grow great big Tahitian pearls.
The industry had been so used to seeing the light colours of Akoya pearls and so no one believed that these huge, dark coloured pearls were natural colour.
Tahitian pearls are grown in what can only be described as paradise, unspoilt islands miles away from civilisation. Oysters are very sensitive to pollution and so the farms are as isolated as possible.
Last but by no means least on our list of pearl types, is the South Sea pearl. South Sea pearls are the biggest of all pearl types.
This large size allows the farmers to nucleate the oyster with a big bead which helps them to yield massive pearls.
The Pinctada Maxima is also capable of layering nacre more thickly and more quickly than other pearl types which contributes to their ability to produce such beautiful, big pearls.
There are two varieties of Pinctada Maxima, the silver lipped and gold lipped oyster. The silver lipped oysters produce beautiful, subtle whites, creams, greys and blue colours whereas the gold-lipped variety produces more of the incredible golden South Sea pearls.
Another distinguishing feature of these pearls is their soft, satin-like lustre. Their incredible size, colour and lustre mean that South Sea Pearls are the most expensive type of pearl to buy.
With some strings fetching many tens of thousands of pounds. Commercial South Sea pearl farming began in North Western Australia in the s, and Australia is still seen by many as the home of South Sea Pearls, but you can also find many fabulous South Sea pearl farms in the Philippines and Indonesia.
The farms themselves go from simple, small businesses to large, complex organisations that use big cruisers as floating nucleation laboratories and sea planes to transport the valuable oysters.
But no matter the size of the business, they all make huge efforts to protect the environment around their pearl farms which in turn protects the oysters, allowing them to stay healthy and produce beautiful pearls.
The wonderful side effect of this is that the farms themselves become areas of outstanding natural beauty where wildlife that is under threat elsewhere, can thrive.
We hope that understanding the different types of pearl that are available to you will help you choose your perfect pearl jewellery. For maintenance tips, how to store your pearls, cleaning and restringing read the following guide which will ensure that your pearls stay beautiful year after year.
Pearls are surprisingly absorbent and need to maintain a certain level of moisture in order to retain their bright colour and lustre.
One of the best ways to do this is simply to wear them. They absorb natural oils from the skin, which tops up their moisture levels. Otherwise they turn a dull, yellowy brown and lose their lustre.
There are also a number of chemicals that pearls are susceptible to when worn. The biggest offenders are:. Finally, we advise caution when wearing pearl rings.
We glue our pearls onto a relatively thick metal post, but a sharp blow or simply wearing gloves over the pearl gardening seems to present a dangerous combination of these circumstances… can break the post or knock the pearl off.
We thoroughly recommend that pearls are kept in a soft cloth, such as the Jersey Pearl pouches, to prevent scratches.
Jewellery boxes contain a lot of sharp edges that can easily damage your pearls. We explain the pros and cons of each cost vs risk to our customers and let them decide, with the cost of their pearls often influencing their decision.
Our string of pearls are individually knotted using two strands of silk thread. The knots prevent the pearls from rubbing together and make sure that only one pearl would be lost if the strand breaks.
Pearl growing oysters are ancient creatures that are very sensitive to their environment. Pearl farmers therefore go to great lengths to keep the water around their oysters clean by preventing pollution, cyanide fishing and dynamite fishing in their local areas.
We therefore promote this important message by doing our bit to help, offsetting the carbon footprint of our jewellery and packaging through the funding of green energy projects.
In partnership with the CarbonNeutral Company we recently helped support the development of a new hydroelectric facility in South Eastern China, providing cheap, clean energy to the developing areas near to where our Freshwater pearls are grown.
