This is a vibrant blue opal with purple tones that weighs in just under 22 carats. It pops off the decolletage when wrapped in 22k gold and set between 18k leaves and oxidized sterling silver. I've added a few clusters of lapis lazuli on 14k pins. The pendant measures 2 3/8 inches by 1 1/4 inches at the widest point and hangs from a chain that adjusts from 18 to 20 inches.
