About 7/8" tall, this mystery charm is the exact size, shape, and color of a green olive. A little black X appears at the top, just like a pitted olive has. A c. 1900 clasp (rose gold colored metal) came on top just like this. How old is this thing? WTF? The material is a mystery. It may be carved olive wood or a huge pit. It's organic, and I see a seam down the middle where two halves were glued together. WEEEIIIRRDDD and wonderful.
