Natural 2.70 carat natural black opal in a free-form bezel setting and 0.26 carat round brilliant diamond pave 18K white gold cocktail ring, showcasing a vivid full-spectrum play-of-color across its organic silhouette with a slim diamond-set shank.

Ring Size 7, adjustable.

The setting is a study in minimalist elegance — a clean, low-profile full bezel of 18K white gold wraps the free-form black opal in a seamless silver frame that lets the stone's irregular natural silhouette speak entirely for itself. The slim white gold shank is set with 37 round brilliant diamonds in a continuous pave line on both sides, adding delicate sparkle that leads the eye toward the spectacular opal center without competing with it. The overall design philosophy is one of restraint and confidence — letting one of nature's most extraordinary gemstones be the sole focal point.

This 2.70 carat natural black opal displays a full-spectrum play-of-color that shifts dramatically across its surface — vivid blues, electric greens, fiery reds, and warm oranges all visible in a single stone, which is the hallmark of a top-quality black opal. Black opals are the rarest and most valuable variety of opal, prized for their dark body tone which acts as a backdrop that dramatically intensifies the color play beyond what lighter opals can achieve. The free-form shape of this stone is entirely natural, preserving the opal's original contours as formed over millions of years, making this a truly one-of-a-kind gem. No two black opals will ever display the same pattern, color distribution, or silhouette — this ring is, by definition, unique in the world.
