All About Pearls
Pearls have been regarded as a symbol of elegance and harmonious beauty for centuries. They are produced by shelled molluscs and are made up from the same substance as the interior of the shell, i. e. from calcium carbonate in minute crystaline form. Shelled molluscs produce pearls when an irritating microscopic object becomes trapped within the mollusc’s mantle folds.
Cultured pearls are not imitations but they are genuine pearls, grown on special farms. cultured pearls are the response of the shell to a tissue implant. A tiny piece of mantle tissue of a donor shell is transplanted into a recipientshell. This graft will form a producing a pearl.
