Following on from our last blog, we continue to supply you with top tips on how to recognise natural pearls.
Natural pearls are RARE The rarity value means that the price a natural pearl commands is usually ten times the price of its cultured counterpart unless the pearl in question is particularly large, of a sought after shape or has been worn by celebrities as is the case of La Peregrina in which case it can go through the roof.
The IT factor natural pearl – One of the most famous seawater natural pearls is La Peregrina a drop shape natural pearl which was discovered in the Americas, it was given by Phillip II of Spain to Mary Tudor as a wedding gift. On her death it returned to Spain and was taken to France. Prince Louis Napoleon sold it to the marquis of Abercorn in 1837, the marquis’s son, drilled La Peregrina and recorded its exact weight, 10.192 grams [ over 50 carats in weight]. When, in 1969, Elizabeth Taylor bought a pearl reputed to be the Peregrina for $37,000, its authenticity was challenged. However, due to the exact record of its weight being kept, experts were able to confirm that it was indeed the famous pearl. It was recently sold again by Christies Auction House, for 10 million dollars plus saleroom fees! Goes to show what celebrity status can do for a pearls perceived value.
Oysters get Blisters! Natural oyster blister pearls can be started by a parasite like a crab that settles in the shell, or a worm that drills through the oyster shell and dies, or larva that obstructs a duct within the shell becomes infected and is then covered with the epithelial cells that protect the mollusc. These pearls have a flat surface on one side because they have been grown on the inside of the shell.
Oysters can bear seed pearls Natural pearls which are 2mm in diameter or smaller are called seed pearls, they were particularly popular in Victorian times, on “parures” a set of necklace bracelets and earrings. Which were tiny pearls sewn onto mother of pearl ornamental shapes and strewn together. Horse hair was used to string the pearls, the horse had to be alive when hairs were plucked from its tail for longest durability and flexibility. The drill holes on these pearls are tiny and only maidens were allowed to make these popular Victorian jewellery sets, presumably because it was only very young eyes who could see well enough to stitch these pearls onto the mother of pearl backs. Dust pearls are also around and as their name implies they are but specks of irritation, not really worth bothering with.

Here are some key tips and facts on how to recognise a natural pearl!
Natural pearl vs not natural pearl … that is the question. On the exterior and to the naked eye, there is no obvious difference between a natural pearl and a cultured pearl. The difference arises from the fact that a natural pearl is formed accidentally and without any human intervention, while a cultured pearl is started by the introduction of an irritant by man, after which the process is continued solely by the metabolism of the living mollusc. In both cases the formation of a pearl is the result of the self-preservation reaction of the mollusc. If it does not get expel the irritant it must cover it in nacre, otherwise it will die.
The chances of finding a seawater natural pearl are 1 in 5000. The term natural pearl implies accidental formation without any human intervention. A natural pearl is caused by the protective reaction of an oyster or mussel to the accidental introduction of a foreign body into its organism. This reaction starts by the mollusc covering the intruder with epithelial cells which will form a pearl sac around the intruder, the pearl sac deposits concentric layers of nacre that surround the offending object and slowly form the pearl, layer by layer. Natural pearls can be formed in seawater or in freshwater.
Make a pearl or … DIE Natural pearls occur when a piece of shell, coral, bone or a large piece of grit hooks into the flesh of the oyster, it breaks the surface of the epithelial cells and carries with it epithelial or nacre producing cells. The oyster tries to expel the intruder but if it is unable to dislodge the irritant, this foreign body will start the formation of a pearl. A grain of sand is hardly ever involved in the production of a natural pearl as the oyster lives in sand and can easily expel it. Elisabeth Strack an eminent pearl specialist of our day discovered another way in which a natural pearl can be formed, refer to the diagram shown, if the epithelial cells covering of the mantle is broken and these crucial nacre making cells travel as a group into the mantle, this in turn will form a pearl sac and a natural pearl will be born.
Stay tuned for part 2! Soon you will be an expert!
Where does a pearl come from ? is a question we are often asked. There are many different types of pearl, some rarer than others, but before we start differentiating between them lets first understand how pearls are formed. Pearls are the product of the act of self-preservation by a mollusc, be it an oyster or a mussel. If the mollusc does not react in this way it will die.
In other words the creation of a pearl is caused by the protective reaction of an oyster or mussel to the accidental or deliberate introduction of a foreign body into its organism. This reaction starts by the mollusc covering the intruder with epithelial cells which will form a pearl sac around the intruder, which in turn deposit concentric layers of nacre that surround the offending object and slowly form the pearl, layer by layer.
So …what is nacre ?
Nacre is made up of calcium carbonate in the shape of tiny crystals called Aragonite. Calcium carbonate is also found in chalk, our teeth and various other everyday items. With a pearl the Aragonite crystals are held together with a glue-like protein called Conchiolin. In our teeth which are also made of calcium carbonate; the protein that holds that Calcium Carbonate of our teeth together is stronger than Conchiolin hence when we are invited to “test” the genuineness of pearls against our teeth it is not only unhygienic but totally undesirable as our teeth will scratch the pearl.
What makes nacre?
Epithelial cells produce nacre and are therefore essential to pearl formation. They are found in a special tissue called the mantle which is found at the hinge and the edge of the molluscs flesh, as seen in the photograph shown. Nacre grows not only on pearls but also as mother of pearl on the interior of the shell. Nacre layers within the shell of the mollusc act as a protective shield against the outside world, making the mollusc less attractive as food to predators. The only difference between pearls and mother of pearl is that in a pearl the layers are concentric and in mother of pearl they are flat or straight.
Where does a pearl gets its lustre from?
Nacre layers play a vital role in the pearl’s lustre. Nacre layers are very thin, translucent and reflect light, thus creating the pearl’s distinctive lustre. Generally the thicker the nacre with regular, thin and translucent layers, the finer the lustre will be on the pearl. In other words lustre is caused by the reflection of light on the surface of the pearl and the refraction of light as it passes through the layers of nacre. This effect appears to make the pearl glow from within.

Diamonds and pearls have to be two of the most beautiful and recognizable gemstones. Here at Coleman Douglas Pearls we can’t get enough of them. Here is a blog post dedicated to the beautiful pairing.
For 1,000 years, starting in roughly the 4th century BC, India was the only source of diamonds. In 1725, important sources were discovered in Brazil, and in the 1870s major finds in South Africa marked a dramatic increase in the diamond supply. The stone’s name is derived from the Greek word adamas, which translates to “unconquerable”.
In ancient Rome, pearls were considered the ultimate symbol of wealth and social standing. The Greeks held the pearl in high esteem for both its unrivaled beauty and its association with love and marriage. Because pearls were (and are) so highly regarded, a number of European countries actually passed laws forbidding anyone but nobility to wear them, a bit like in the 18th century and beforehand when only royalty were seen with diamond engagement rings.
Putting these two gemstones together make for the absolute perfect engagement ring or gift for your loved one. They both represent eternal love and strength. As we adore pearls here at Coleman Douglas, we’ve got the most beautiful collections to show you. If you’ve got an idea in mind as to what you’re looking for (and you have some pearls in a locked drawer somewhere), bring them in and we’ll transform them into your perfect piece of jewellery.
This week the team at Coleman Douglas Pearls have decided to showcase just how well Pearls match with everyone’s favourite metal, Gold.
Why do we love gold so much? It was the first metal to be widely known to the human race, beautiful, shiny and malleable it has been the favourite ever since. The Incas referred to gold as the “tears of the Sun” which is rather romantic. Gold is dispersed widely throughout the geologic world, its discovery occurred to many different groups in many different locales, and nearly everyone who found it was impressed with it as was the developing culture in which they lived. Gold’s early uses were ornamental, and its brilliance and permanence (it neither corrodes nor tarnishes) linked it to deities and royalty in early civilizations. It’s never gone out of fashion and we don’t see it ever doing so any time soon.
With Gold being ‘tears of the sun’ let’s match it with our favourite gemstone and what the Georgian and Victorian eras symbolized Pearls as “tears of mourning”. The earliest record we have of pearls as precious objects are artifacts from Mesopotamia dated to around 2300 B.C and recently, a two thousand year old pearl was found in an Australian Aboriginal archaeological dig in the Kimberley region of Western Australia. The Persian Gulf was one of the main sources of natural pearls for centuries, as were Venezuela & Panama where pearls were discovered by Christopher Columbus and Vasco de Balboa on their travels. Natural ‘real’ pearls are very rare these days and are worth thousands. Cleopatra won a bet that she could provide Marc Antony with a banquet costing more than the assets of a country. She took off a pearl earring, dissolved it in wine and drank it. How’s that for value!
We have lots of variations of pearls, gems and metals and don’t forget that we create bespoke designs, so if you have any of grannies pearls and gold lying around come in and meet our pearl specialist and designer Chrissie Douglas who will come up with a beautiful new design and make a match made in heaven.
Hope to see you at our studio soon at 42 Beauchamp Place, Knightsbridge, London.
