Australian Solid Boulder Opal 4.75cts 17.5x9.8mm

Description

Fluorescent Greens and Reds dominate this boulder opal from Australia. On some angle it almost appears like a Christmas tree with just green and red, then turning the stone an 1/8th of a turn, and you see pinks and blue and so mayellows and more. A miracle of natural color and style. This a 100% natural opal, no additives or treatments, not a doublet, not a triplet, the real McCoy.
