Vintage Gold-toned Metal and Jade Stone Dress Clip

Vintage gold-toned dress clip, or scarf clip. I think it looks rather Mideval, or celtic. It has a real green stone at the center, but I can't tell what kind of stone this is, as it is the right shade of green to be jade, but jade tends to be more translucent than this one. Anyway, this is a beautiful, diverse mid-century accessory that you can style in any way you wish. Perfect vintage condition.
