Natural pearls are formed when a specific type of irritant, could be a parasite or a sand particle enters into the mollusk, when it open its valves for respiration or to take food, to protect the mollusk from intruder it starts secreting a compound over the irritant known as “Nacre”. And that years and years of secretion makes several layers of nacre over the irritant which finally forms the Pearl.

Finding a natural pearl now is very rare thing. Probability of finding natural pearl is 1/10000.

Cultured Pearls

Cultured pearls are also natural pearls, but here the irritants are planted inside the mollusc shells by humans in control environment. There number of methods for producing cultured pearls. Technicians very gently implant the bead with a mantle tissue in a living mollusc. Bead is also known as nucleus around which the nacre is secreted, which finally result in the formation Pearl. This technique of culturing pearls is very tricky and requires special skills.

Natural pearls can be distinguished from cultured pearls through the use of X-Ray, which reveal the bead inside the cultured pearl.
