This Solid GEM-Quality Semi-Black Opal from Lightning Ridge is of SUPERB quality! Its rare "FLAG-HARLEQUIN"* pattern showcases a full color spectrum of Reds, Oranges, Yellows, Greens, Aquas, Blues, Purples and even the elusive TURQUOISE! All the colors jump to life with the slightest movement of the stone. There are no dead-spots and the opal is non-directional! The performance is perfect in all types of light, and even very reduced natural light brings out the "fire" in the colors! The opal shows a lot more red than you see in the picture. Cut in a calibrated size. *See "A Field Guide To Australian Opal" by Barrie O'Leary.
