Vintage Mother of Pearl and Marcasite Earrings

These were cufflinks in a previous life. I purchased them from ebay sellers ace of diamonds. They are 14K white gold earwires that catch in the back so there is no way to loose them and they have a very nice swing to them. I have 12 pair of earrings from this seller and I have a pair so similar to these that I thought I'd offer them up here... Please ask any question you have about them, they are a one of a kind vintage re-purposed piece.
