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

A show-stopping 18K black opal triplet ring, custom made and with mega proportions! The oval fancy cut opal triplet measures 22.5 x 12mm and dances with a big, bold color pattern of electric greens, saturated blues, and dashes of fuchsia. The pattern and color play reminds me of the shimmery magic of a blue morph butterfly wing: I enjoy the large patches of color. 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. This stone is bezel set with a milgrain edge and a flat, polished "sill." Roomy setting and curling gold wire detail around the gallery. Nearly 10 grams total weight and a TOTAL stunner! 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.
