2.91 Ct. Cabochon Black Opal from Ethiopia

From the volcanic highlands where molten silica settled and cooled, this opal began as a whisper in rock, a slow weaving of color that took millions of years to finish. Found in Ethiopia, a place that has changed the map of opal history with its vivid discoveries, this stone carries the land with it. The dark body tone that classifies it as a Black Opal allows the internal rainbows to glow with theatrical intensity, a private light show kept within a polished dome. At The Natural Gemstone Company we trace each gem back to its origin, and this pear shaped 2.91 carat multi color opal comes to you untouched by treatment, a natural formation, a true expression of the earth, with no enhancement.

The gem itself measures 13.83 x 9.50 x 5.49 mm, shaped into an elegant pear form and finished as a cabochon to maximize its play of color. Its multi color display shifts and dances against a dark canvas, offering flashes that read as fire, sea, and aurora depending on the angle and the light. The clarity grade is very slightly included evaluated at eye level, a detail that assures its natural character while leaving the surface visually clean and arresting. The polish is excellent, the dome is smooth, and the silhouette is sculpted to capture and return light, making each movement of the wearer a deliberate reveal of the opal’s inner life.

Size and clarity combine in this stone to create an ideal candidate for a statement piece that reads as both modern and timeless. At nearly 3 carats and with a length that flatters the neckline or the finger, this opal commands attention without needing excessive metalwork. A solitaire pendant will let the pear shape suspend like a droplet of night sky, a cocktail ring can use a low or high setting to show off the vivid color flashes, and a bespoke bezel or minimal prong setting will protect the cabochon while allowing light to enter and bounce back. Because the piece is natural and untreated, handling and setting should respect the gem’s nature, and our team at The Natural Gemstone Company can advise on the best mounting choices to enhance stability and spectacle.

Beyond the measurements and grades, this stone tells a story that will travel with the person who wears it. Ethiopian opals have already forged cultural connections, inspiring jewelry makers and collectors with their surprising color and vitality, and this Black Opal is a chapter in that ongoing story. Imagine the opal resting at the center of a design, catching a candlelit smile or a bright noon glare, creating an intimate conversation between wearer and gem. We stand behind the provenance and quality of every piece we offer, and we welcome you to ask about setting options, design ideas, or to request additional photographs and video to see the play of color in motion. Let The Natural Gemstone Company help you turn this rare 2.91 carat pear shape opal into the signature piece it was meant to be.
