Vintage 1950s "Fire Opal" & Rhinestone Y Drop Necklace. Elegant 1950s piece with marquise-cut FAUX "Fire Opal" (closet I've seen to Dragons Breath without actually being it, so stunning) stones and clear round rhinestones. The piece is set in a silver-tone metal frame with a classic tennis-style chain. It has a secure fold-over clasp closure and a decorative drop pendant at the center. There's a 7 inch drop on this necklace.
