The Beautiful Peacock: 37.21-CT Oval Black Opal

This beautiful, 37.21-carat black opal in an oval shape looks like a painter’s palette with the finest hues of predominantly green and blue. But unlike the flat surface where a painter arranges and mixes paints, this black opal’s incredible colors occur because opal is composed of sub-microscopic spheres stacked in a grid-like pattern that break up light into spectral colors.

This black opal’s particular play-of-color pattern, called “peacock,” is similar to the iridescent blue and green colors of a peacock’s plumage, hence the name. The high polish on the cabochon cut adds to its appeal. A rare gem, this black opal will make any jewel a glorious work of art.
