Manual on Pearl Culture techniques

Pearl culture is an art concerned with biological production of one of the finest gems, the pearl, nature's perfection of beauty and splendour. It is produced by the pearl oyster, a bivalve mollusc, living on an insignificant ground at the sea bottom. Man has known this gem right from the period of early human civilization and had adorned himself and his woman with pearls and had offered them to his gods. The soft colour and cool lustre of pearls produced by the oyster remain unmatched by any of the gems processed by man.
