Black Mother-of-Pearl 25 x 18mm Oval Cabochon

This black mother-of-pearl oval cabochon features a pearly, iridescent “oil-slick” color that complements a variety of metal types. Use it as the centerpiece of a pendant or brooch, or as the front of a decorative button. Partner it complementary-color cabs to create matched sets with brooches or earrings, or use it to create more complex, multi-stone necklace designs.Named for its resemblance to the finish and color of pearls, mother-of-pearl cabochons are made from the hard, iridescent material that forms on the inside of some shells and shellfish. It is used for inlay and to create beads, cameos, cabochons, buttons, and other ornamental objects.
