I would date this stunning necklace to the 1940's. The red rhinestones are such a deep color they could be mistaken for garnets. The necklace center has an art nouveau look. Necklace is about 19" long. The three piece center is 2 7/8" across and 1 1/4" long at the middle. The chain looks like brass but I am not certain that was the metal used. This beautiful necklace is in excellent condition with old patina on the chain.
