Here is a sweet cameo pin / pendant. It is made of sterling silver, black onyx, carved mother-of-pearl and marcasites. It has a bale on the back so it can also be worn on a chain. It is stamped 925 for sterling with another hallmark that I am not familiar with. Measures 1 1/4" X 7/8". Weight is 6.99 grams. Excellent condition.
