This is a stunning necklace and pendant set. Signed KC on the gold tone frame, there is what I believe to be a slice of boulder opal embedded under the glass front of the round pendant. The necklace is made up of deep maroon red glass elongated beads, tiny glass opalescent beads and gold spacer beads. The necklace measures 18 1/2" in length, including the 2 1/2" extender chain. The pendant measures 1 1/4" across. This is a wonderful discovery.
