This is a beautiful pendant necklace. The metal frame of the pendant has a burnished background with goldtone highlights and is set with a huge purple rhinestone which is unfoiled and open backed. I would date the pendant to the 1930's. It comes on a gold filled chain which would have been a later addition but absolutely perfect with the pendant. The chain is 20 1/2" long and is marked on the spring ring clasp. The pendant is 2 1/4" x 1 7/8" across with no markings. Someone has cleaned the metal and this has highlighted the embossed design. There is a small rough spot on the back of the pendant but the front is in excellent condition.
