A magnificent Art Deco opal cocktail ring. Being one of the rarest and sought after gemstones, this Lightning Ridge Australian black opal is a top quality collectors' specimen. Known as a harlequin for its distinctive colored patches that displays a brushstroke pattern that draws your eye as the color dances throughout the gem. Although the opal takes the stage, you can't help but notice the incredible detail throughout the whole ring. The scalloped platinum statement ring is studded with glistening diamonds supported by a bounteous under-gallery with highly detailed, open work motif filigree.
