I have never investigated this. They are gold with a seed pearl in the center. There's a draped ribbon of silver below. A gold bead hangs from the bottom.The background and trim is black enameled. I don't feel comfortable wearing dangling earrings, so I reluctantly decided to sell them. I hope they go to someone who will appreciate the design and the workmanship.
