These are sustainably sourced baroque freshwater pearls. They are big! Size varies from 9-11mm. 22k yellow gold plated panther clasp with Austrian crystals, pearls are hand knotted in silk cord. Kindly note on last picture, the panther in the new stock received has green eyes, not red. Pearls are identical. Baroque pearls are like fingerprints, no 2 are alike. They have ridges, layers and marks. That's mother nature. How to tell if a pearl is real: rub it against your teeth and it feels gritty.
