Black Opal and Diamond Ring

A monumental 21.39-carat black opal displays a kaleidoscopic panoply of cool greens and blues at the center of this ring. Opals are among the most desirable gems in the world, and black opals display the most brilliant colors of all. Nearly 3.00 carats of glittering white diamonds further distinguish the multi-colored gemstone, accenting the 18K white gold band.
