There are several reasons for the different colors of pearls. The most important is the mollusk species along with the donor or mantle tissue that is inserted into the gonads of the cultured pearl sac. There is also the chemical condition and pigmentation of the water source where the pearls are grown.
I love to take you on a visit to a pearl farm every once in awhile.
Pearl farms are fascinating for many reasons, but most importantly, they can only exist in some of the most clean and sustained water conditions. They are wonderful places to visit.
At over 700 pages long, I go to Strack's book whenever I have a question about pearls.
Abalone pearls are a rare natural pearl. The mollusk, Haliotis is the mother to these iridescent pearl. But she is unable to clot her wounds and thus it is impossible to implant a nucleus to culture a pearl. She would die of bleeding, as a hemophiliac.
Until recently...
I am sharing a video that I took at the Ha Long Pearl Farm in Vietnam of a worker implanting an oyster so it will "grow" a pearl.
