2.91 Ct. Semi-Black Opal from Australia

From the weathered red plains of Australia to the quiet bench where it was shaped and polished, this semi black opal carries a story written in layers of light. Formed over millennia as silica rich waters seeped through cracks in ancient rock, this 2.91 carat gem began life as a simple deposit that captured sunlight and time. In its rough state it was a promise of color, a hint of fire beneath a pale surface, and skilled hands saw that potential and chose to reveal it rather than to force it. The result is a beautiful translucent multi color opal, a semi black opal that plays with depth and glow. Its fancy shape and tablet cut measure 19.68 by 11.37 by 2.21 mm, dimensions that speak to both presence and grace, a size that feels substantial without overwhelming. At The Natural Gemstone Company we celebrate stones that arrive with their natural soul intact, and this opal is a representative of the Australian fields where nature and patience conspire to produce something rare.

The transformation from rough to the finished tablet cut was a careful negotiation between the stone and the cutter. The tablet style preserves a broad, slightly domed surface that allows the opal to present a wide stage for its internal color flashes. This particular opal shows intense color intensity, a living mosaic of electric blues, vivid greens, and fleeting ribbons of warm orange and red when angled to the light. Its translucency gives the colors a sense of depth, as though you are peering into a luminous landscape rather than merely at a surface. Evaluated at eye level the clarity grade is very slightly included, which means inclusions are minimal and do not detract from the jewel s visual performance, they even add character without compromising durability. The polish is excellent, providing a mirror smooth face that amplifies the play of color and invites touch. Importantly, this opal is untreated, no enhancement, a natural treasure straight from Australian origins to your hands.

Stones carry stories of where they have been and of who will bring them forward, and this semi black opal is a storyteller s gem. Designers often choose the tablet cut for pieces that require a broad canvas, such as a pendant that lays gracefully against the sternum, or as the dramatic centerpiece of a custom ring. At 2.91 carats it offers flexibility, equally suited to an intimate bespoke engagement piece or a striking cocktail ring. The soft triangular curve of its fancy shape encourages creative settings, a low bezel to protect the edges while allowing light to enter from the side, or an open back to intensify the color play under varied lighting conditions. Jewelers I work with at The Natural Gemstone Company frequently recommend settings that honor the stone s translucence, allowing the natural glow to become part of the jewelry s personality. For someone seeking a signature item that reads as both contemporary and timeless, this opal answers that brief with ease, carrying both the rugged provenance of the Australian fields and the refined touch of masterful lapidary work.

Owning a gemstone is entering into a relationship with an object that is both fragile and enduring, and this semi black opal requires gentle care while promising decades of admiration. Keep it away from harsh chemicals, sudden temperature changes, and prolonged exposure to direct sunlight, which can alter the stone s moisture balance over long periods. Clean it with a soft cloth and mild soapy water, avoid ultrasonic and steam cleaners, and store it separately to prevent abrasion from harder gems or metals. When set by a trusted jeweler, this opal will become an heirloom, a piece that carries its Australian narrative forward with every wear. At The Natural Gemstone Company we stand behind the authenticity and provenance of this opal, offering it as a no enhancement, naturally vivid example of semi black opal beauty.
