This sky blue boulder opal weighs in at over 13 carats. The opal flashes blue, green, pink and tangerine. I've framed it in a dense fringe of freshwater pearls with a few gemstone beads (sky blue topaz, tanzanite, pink sapphire, green tourmaline) dotted along the edges to highlight various colors of the opal.
The chain adjusts from 16 to 18 inches.
The argentium sterling silver (.935) with enhanced tarnish resistance has been given a brushed finish.
