Photos don't do this Australian Boulder Opal justice. The deep and flashy lines of ultraviolet running through the warm brown matrix are truly beautiful. It is prong set next to a sweet dendritic agate wrapped in 22k gold. A fanciful coated topaz, rhodolite garnet and amethyst round out the color play and mingle among sprigs and sprouts and grasses of oxidized silver and 18k gold leaf accents. The pendant suspends from a silver chain that adjusts from 16 to 18 inches.
