Beautiful 18k Chain & Lovely Diamond Decorated 18k Gold Locket. The locket weighs 55.7 grams nearly 2 troy ounces. Both the chain and the locket are in excellent condition. The necklace portion measures 15 inches long and is 7 1/2 mm wide. The locket measures from the top loop to the bottom of the locket 2 inches long and 1 1/8 inch wide. The crystal picture cover has a semi-circular crack on the left side as you look at. It holds the picture in just fine though.
