This dramatic boulder opal gives the impression of a rocky landscape at night with a swirling sky of blues and greens. I've set it in silver and surrounded the opal with a lush fringe of lapis lazuli, turquoise, blue topaz and tsavorite garnet. The lapis lazuli are on silver headpins and the turquoise, topaz and garnet are on 14k pins. The chain adjusts from 16 to 18 inches.
