Exquisite piece with charming beads of yellow, white and copper inside clear glass. The yellow and white have an almost floating opal effect. Three strands. Each bead has an end cap and spacer bead. Filigree clasp is marked Sterling and has a manufacturer's mark resembling a partial triangle. The shortest (top) strand wears at 15 inches around the neck. A quality necklace and it wears beautifully! Ca., 1940's and is in very good condition.
