Opal, Oval Shape, 5.78 CT


This fine 5.78-carat black opal, certified as natural by the Gemological Institute of America and of Australian origin as certified by the American Gemological Laboratories, looks like a painter’s palette with the finest hues of blue, green, yellow and orange. But unlike the flat surface where a painter arranges and mixes paints, this black opal’s incredible play-of-color occurs 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 “harlequin,” shows small, close-set patches of warm and cool colors against a black body color. A rare gem, this black opal will make any jewel a glorious work of art.
