While it is known that pearls are made of calcium carbonate with an organic matrix core, the role of the proteins modulating the organization of these crystals has, until recently, been unclear.

Oysters are the main producers of pearls, but clams and mussels can also create them. Pearls form when oysters secrete layers of nacre around irritants. There are natural and cultured pearls, with ...

For centuries, researchers have puzzled over how oysters grow stunningly symmetrical, perfectly round pearls around irregularly shaped grains of sand or bits of debris. Now a team has shown that ...

ARLINGTON, Va. (AFPN) -- Scientists from the University of Dayton Research Institute have manipulated the process of shell and pearl formation in oysters to demonstrate a method for depositing ...

The first person who discovered pearls must have believed he stumbled across a bit of magic. Pull apart the valves of a living oyster, and a beautiful spherical gem of calcium carbonate may lay inside ...

B far the greater number of recent writers on pearls, whether “L'scientific or otherwise, when discussing the cause of pearl-formation, have contented themselves with recapitulating what has already ...
