This large sterling silver pendant is set with a gray stone. It could be quartz. I am just not sure. The frame is well decorated and pendant is signed on the bale. It says 925 and then has a name which I cannot read. The chain is sturdy and marked Italy 925. Pendant is 1 3/4" including the bale and 1" wide. Chain is about 24 3/8" long. Necklace weighs about 30 grams and is in excellent condition.
