Vintage Sterling Silver Small Amber Cabachon Crab Brooch Pin. Very adorable Crab pin! It is not marked Sterling but has tested for it. I am sure the Amber is synthetic because it feels like plastic. In good vintage condition does show minor signs of wear due to normal use and age. Has Silver tarnish and can be cleaned I do not clean jewelry as some customers do not prefer this. Shipped with USPS First Class Mail.
