Aloha,
These earrings are handmade with pīkake, or jasmine flowers made from mother of pearl. Pīkake are very fragrant and often used for leis here in Hawaii. They can also be found here on Kauai. The mother of pearl has a sheen that reflect differently in the light. The hammered 14k gold filled wire give them a nice texture.
Ear wires are 14k gold filled.
Since these are handmade, one of a kind, they may have minor, yet appealing imperfections.
Mahalo!
