Sculptural Boulder Opal, Peridot, Tanzanite, and Sapphire Ring

Sculpturally set in 18K yellow gold, this extraordinary 7.73-carat boulder opal displays an intensity of color and saturation that is profoundly uncommon. The surface is a swirling cosmos of electric blue, deep green, and shadowed indigo, with subtle flashes of purple, a color phenomenon second rarest in opal, next to red.

While most opals are more translucent in nature, this stone is rare for its profound density of material, creating an opaque body with vivid hues that appear in unusually dense concentration across a large, uninterrupted face. This makes the specimen exceptionally rare and gives it a presence that feels almost geological, elemental, and alive. An opal such as this would have formed under the most fortuitous geological circumstances, where silica, pressure, and time work in perfect harmony in the host rock, creating a gem that reveals not just color, but depth, weight, and an almost artistic dimension.

Complementing the opal’s natural drama is an artful trio of accent gemstones: a 0.30-carat pear-shaped peridot, a 0.35-carat square tanzanite, and a 0.05-carat round sapphire. Their geometric arrangement mirrors the modern design era of the 1980s, while their colors echo the opal’s own internal spectrum, creating a composition that feels both curated and intuitively organic. These gems echo and amplify the opal’s chromatic spectrum, adding sculptural balance and contemporary sophistication.

Indistinctly signed and entirely bezel set in a sculptural, almost architectural setting, the ring bears the hallmarks of a custom piece, designed and crafted singularly around a stone of genuine importance. Artistic and bold, this one-of-a-kind ring embodies the expressive jewelry design of the 1980s, centered with a truly extraordinary gemological specimen.

This ring is a size 8 and sizeable to your needs.
