COMMENTS: A spectacular Australian black opal, weighing 1.86 carat, performs a magical display of electric rainbow colors (all of them especially the rare red color!) from within a sparkling halo of small bright white round brilliant-cut diamonds, in this superb and stunning estate jewel rendered in rich yellow gold. Depending on the angle and lighting source the fabulous gemstone transforms from a predominant palette of cool blues, purples and greens to flashes of fiery yellows, oranges, and reds. An enchanting gem. _x000D_
