I was just looking at this and it looks like a spider, but I realized that it only has 6 legs. So, I guess it's an ant. Anyway, this tests to be sterling silver. It's silver with turquoise head. The legs are applied, the eyes and the end of the antennas are little raindrops of silver. It has a safety clasp. It measures 1 inch by 15/16 of an inch.
