Unique and vintage, an oblong (what looks to me like )ivory or bone, has a piece of tortoise like amber with a mother of pearl silhouette of a woman in a hat, very 1940s. The fob has a hole carved into it at the top to accept a ring for a necklace. It is in good condition with some chips out of the edge of the "amber". Also it is scratched but not on the MOP part of the lady. Its really cool and unique- I have never seen anything like it. I cannot guarantee what the materials are that make it up.  It measures 1 5/8" long.
