At over 700 pages long, I go to Strack's book whenever I have a question about pearls.
Baroque is a description of a pearl that is non-symmetrical and shaped irregularly. More importantly, barroque (french spelling) was first used to describe pearls. It was not until the 17c. that Baroque came to mean a form of art and architecture.
But, what exactly is a baroque pearl and are they valuable?
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.
This very large 127.5 carat pearl is a silvery white Baroque pearl. In the Renaissance period, Baroque pearls were highly valued for their unique shapes, which highlighted their luster and colors.
