Beautiful vintage glass pear-shaped opals, sparkle in pink, green and gold under a swirl of cloudy glass. The opals measure 18 millimeters by 13 millimeters or about three-quarters of an inch by half an inch. They are set in vintage open backed crown settings that allow the translucent stones to be softly back lit. Secure brass plated lever backs, ornamented with a tiny shield, suspend the opals. This simple style works well for destinations both casual and formal.
