This is an antique Chinese carved jade pin. It’s got little holes around the edges. The back metal has a gold color, but it’s more likely brass or bronze. I tested it for 14k and it failed. Definitely an old stone and has some areas of yellowing. It measures 1 3/4″ long and 1 1/8″ wide. If you have any questions please message me. Since I took the pictures for this under artificial light I wanted to add a few more showing it under natural lighting so that the colors showed a little more. I blew some of it away after I noticed it in the picture, but you can see the before and after in the pictures below.
