Pearls, just as amber, jet, fossils, mother of pearl, and other substances used in magic, is the product of a previously living creature. Some believe that due to the fact that the oyster must die to remove the pearl, that there is a heavy debt incurred by those who engage in trafficking pearls, as well as those who wear and use them. The choice is yours...you will know intuitively whether you can use them or not.
Pearls are intimately connected to the moon, so much so so that some will wear or use them only at night, during the moon's domain.

Mabe Pearls From The South Seas

A mabe pearl is a hemispherical shaped pearl which is grown against the inside of the oyster's shell, rather than within its tissue. Mabes occasionally appear in nature.
Mabe Pearls Develop On The Shell
Cultured mabes are grown intentionally, by using a hemispheric nucleus, rather than a round one; and by implanting it against the oyster's shell, rather than within its tissue. The pearl then develops in a hemispheric form, with a flat back. While in the oyster a mabe pearl is actually considered a blister pearl not a mabe pearl.
