Vintage 1980s 18K yellow gold custom fancy opal triplet cocktail ring

A kaleidoscopic black opal triplet ring in nearly 13 grams of 18K yellow gold, custom made and with mega proportions! The oval fancy cut opal triplet measures 30 x 12.5mm and dances with a big, bold color pattern of electric greens, saturated blues, and dashes of fuchsia. The specimen is bezel set to follow the natural shape of the stone. Opal triplets are made up of a backing layer (base), an opal slice (middle), and a clear "dome" (top). The quartz top serves to protect the opal specimen and the backing accentuates the already dark body color of the gem. Doublet and triplet opals are a clever and dynamic way to make gorgeous specimens affordable without sacrificing gemstone color or quality.

I acquired this ring from the estate of a world traveler and I believe she purchased the stone - and possibly the entire ring - in Australia on one of her many tours.
