1.67 Ct. Multi Color Black Opal (Dark Opal) from Australia

From the slow hush of prehistoric oceans to your jewelry box, this Black Opal, Dark Opal tells a story written in light and time. Born deep within the weathered seams of Australia, a silica gel once settled into tiny cavities and laid down layer upon layer over geological ages, each microscopic sheet trapping and bending light until flashes of color were forever sealed inside. Weather and pressure sculpted rough nodules until miners found pockets where darkness and fire met, and from one of those pockets came this exquisite 1.67 carat oval multi color black opal, a dense jewel that carries the memory of ancient seas. Its dark body tone forms a stage for an intense play of color, a vibrant choreography of blue and green that rises and falls like distant auroras, and every viewing angle reveals a new arrangement of color as the internal structure whispers the long history of its formation.

When the rough reached our hands at The Natural Gemstone Company, we set out to honor that story with a cut that would preserve both depth and drama. The cutter chose a tablet cut, a tablet style that emphasizes a broad, shallow surface to maximize the opal’s flashing patches, and the result is a refined oval tablet measuring 10.20 x 8.12 x 3.18 mm. In the workshop the lapidary worked with patient, practiced strokes to reveal a face that gleams with an excellent polish, each stroke aimed at releasing the stone’s internal light without sacrificing its integrity. At eye level the clarity reads very slightly included, which means the gem retains a natural, honest character while presenting a clean, striking field of color that reads as intense. No enhancement has been applied, so what you see is the genuine art of nature and the careful hands that shaped it, intact in weight and form, ready to become the centerpiece of a design that celebrates raw, authentic beauty.

This 1.67 carat oval multi color black opal, with its tablet cut and rich Australian origin, invites both emotional connection and practical consideration as it moves from narrative to daily wear. Imagine this dark opal set in a simple bezel to frame its shifting greens and blues, or suspended in a custom pendant where light can dance across its surface with each step, the oval silhouette flattering and timeless. Its intense color intensity and excellent polish ensure that the visual impact remains strong even in modest settings, while the very slightly included clarity gives the stone a genuine provenance that collectors and designers alike admire. Caring for a Black Opal, Dark Opal is straightforward, treat it as a delicate treasure, avoid harsh chemicals and extreme heat, and store it separately to preserve its polish and play of color. At The Natural Gemstone Company we stand behind the origin and integrity of this piece, offering a gem that is unaltered, responsibly sourced, and masterfully finished, a small geological epic that you can wear, pass down, and cherish as both an object of beauty and a piece of the earth’s long story.
