A natural pearl (often called an Oriental pearl) forms when an irritant works its way into a particular species of oyster, mussel, or clam. As a defense mechanism, the mollusk secretes a fluid to coat the irritant. Layer upon layer of this coating is deposited on the irritant until a lustrous pearl is formed.

How long does it take for a pearl to form?
Some pearls can develop in a period of six months. Larger pearls can take up to four years to develop. This is one of several reasons why larger pearls can yield higher values. Pearl farmers must have immense patience to wait for a pearl inside an oyster shell to develop.
Are oysters killed for pearls?
99.99% of pearls sold are cultured. ... Thus each and every pearl, whether cultured or natural, represents hundreds and thousands of oyster shells being opened up and discarded, resulting in their death. Pearl oysters that are discarded are not channelled as food because oysters are eaten alive or cooked alive.
What is a pearl made of?
Just like the shell of a mollusk, a pearl is composed of calcium carbonate (mainly aragonite or a mixture of aragonite and calcite) in minute crystalline form, which has deposited in concentric layers. The ideal pearl is perfectly round and smooth, but many other shapes, known as baroque pearls, can occur.
How are pearls made artificially?
Natural pearls are initiated in nature more or less by chance, but cultured pearls are human-initiated, formed by inserting a tissue graft from a donor mollusk, upon which a pearl sac forms, and the inner side precipitates calcium carbonate, in the form of nacre or "mother-of-pearl".
Do all oysters have a pearl?
Pearls that form naturally inside of oysters are called natural pearls. Sometimes oysters get a bit of help from pearl harvesters, though. ... While any oyster — and clams and mussels — can produce pearls, some species of oysters are more likely to produce pearls, while others may be harvested primarily to serve as food.
Are pearls alive?

Are pearls vegan?

Are pearls rare?
Natural pearls are actually very rare, mostly because pearl-producing species of mollusks were nearly hunted to extinction with most natural beds of pearl-bearing oysters depleted by over-harvesting in the 18th and 19th centuries. Today, natural pearls are extremely rare.
Is a pearl made out of sand?
Pearls are made when a small irritant finds its way inside an oyster or mollusk. This can be a grain of sand or a piece of shell but is more typically a little parasite. ... Nacre is the substance that coats the inside of an oyster or mussel's shell. The nacre coats the irritant, and the layers build up over time.
Why do oysters grow pearls?
Pearls are made by marine oysters and freshwater mussels as a natural defence against an irritant such as a parasite entering their shell or damage to their fragile body. ... This creates a material called nacre, also known as mother-of-pearl, which encases the irritant and protects the mollusc from it.
How do pearls form naturally?
A natural pearl (often called an Oriental pearl) forms when an irritant works its way into a particular species of oyster, mussel, or clam. As a defense mechanism, the mollusk secretes a fluid to coat the irritant. Layer upon layer of this coating is deposited on the irritant until a lustrous pearl is formed.
