NUCLEUS AND METHOD FOR PRODUCING HALF OR MABE PEARLS |
摘要 |
The invention relates to a nucleus for the production of half or mabe pearls in molluscs. The nucleus comprises a first portion having an external surface adapted to define the shape of the half or mabe pearl to be produced and a second portion which defines a bridge between said first portion and the shell of the host mollusc. The half or mabe pearls so produced have a substantially even cross section of nacre formed over the nucleus, and a generally reduced time is required for the formation of the pearl. |
