Lovely sterling necklace with marcasites and a center pearl. The pearl measures 7/16" X 3/8". It is very white with a great luster and no damage. The piece that it is bezel set into measures 1 3/8" X 5/8". The chain is quite unusual as it is actually a double chain connected by small flat square pieces of silver. It is stamped on the back 925 with the letter "G". The spring ring works well and is also stamped 925. Measures 18 3/4" in length. Excellent condition.
