Few Australian 'Lighting Ridge' black opals come as fine and fabulous as this spectacular specimen presented in its original Art Deco splendor - circa 1930. The beautifully proportioned oval cabochon bursts with a multichromatic explosion of electric confetti colors against a deep black matrix background. The gem is embraced by an elegantly designed mounting, hand fabricated in platinum and sparkling with three-quarter carat of bright white diamonds. Entrancing, enchanting, sublime. By Brock & Company, an early-to-mid-twentieth-century, high-end, downtown Los Angeles jewelry retailer. Just shy of 1 inch long, currently ring size 7 1/2.
