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.

Here at Coleman Douglas Pearls we understand that there is a lot of mystery behind pearls and how they are formed into beautiful pieces of jewellery, but there doesn’t need to be. It’s quite simple really.
As you probably know, they are created by oysters and mussels. Oysters tend to only produce one pearl in its lifetime whereas mussels can create up to 120 pearls. Pearls are a result from the protective reaction of an oyster or mussel to accidental or deliberate introduction of a foreign body into its organism. This reaction creates concentric layers of nacre (mother of pearl) which are deposited on the foreign body covering it completely.
No two pearls are the same. They usually have some form of irregularity which all adds to the natural aspect of this lustrous gem.
There are four main types of pearls that we sell here at Coleman Douglas Pearls, there are South Sea, Tahitian and Akoya pearls which are formed in oysters and there are mussels formed freshwater pearls.
South Sea Pearls– tend to be 9-14mm in size and are produced in Australia, Indonesia and the Philippines. They vary in shades of white and gold.
Tahitian Pearls are similar in size to the South Sea pearls but come in a variety of colours from white to deep black through aubergine and blue, all shades have a grey over tone. Tahitian pearls are mainly produced in Tahiti (surprise) French Polynesia and Mexico although some can be found in Autralia.
Akoya pearls were first cultivated in Japan, their size varies from 3-10mm in size and in colour they range from pink through to white, gold and grey.
Freshwater pearls are produced mainly in China and are the easiest to access type of pearl but beautiful none the less. Some of these pearls can be called Biwa pearls which this is a generic name as the most famous freshwater pearls originated in Lake Biwa in Japan.
