1.15 Ct. Cabochon Semi-Black Opal from Australia

I am pleased to present a stunning, translucent 1.15 carat oval multi color opal from The Natural Gemstone Company, a gem that will catch the eye and hold attention whether set in a ring, pendant, or a pair of earrings. This beautiful Semi-Black Opal measures 8.10 x 5.37 x 4.07 mm, and it has been expertly shaped into a classic oval cabochon. The cabochon cut enhances the stone top, allowing the full spectrum of play of color to reveal itself across the surface. Evaluated at eye level, the clarity is eye clean, free from visible inclusions that might distract from the opal carriage of color, and the surface has been given an excellent polish to maximize light return and tactile smoothness. This opal is completely natural, with no enhancement, and it originates from Australia, a source renowned for producing world class opals with vibrant and varied color presentations.

Visually, this Semi-Black Opal displays intense color intensity that ranges across vivid greens, electric reds, warm oranges, and flashes of cool blue, depending on the angle of light and viewing position. The semi black base tone gives the colors a dramatic contrast and depth that lighter body tones cannot match, creating a more saturated and striking appearance. Because the gem is translucent rather than opaque, some light penetrates and refracts internally, producing a floating mosaic effect where individual color patches seem to dance and shift as the stone moves. The combination of the oval shape and the cabochon dome enhances broad color patches and contributes to a balanced, symmetrical presentation ideal for both classic and contemporary designs. At 1.15 carat and with these exact dimensions, the stone is perfectly proportioned for an elegant solitaire ring, a refined pendant that sits flush against the skin, or a set of coordinating jewelry pieces that require a primary focal stone with significant color impact.

From a practical and design perspective, this opal is versatile and uniquely wearable. Semi Black Opals are celebrated for their ability to showcase a wide color palette under many lighting conditions, making this gem an excellent choice for a piece of jewelry meant to be seen in both daylight and evening light. For metal pairings, warm yellow gold accentuates the red and orange flashes, while white gold or platinum offers a contemporary frame that highlights green and blue tones. Rose gold can provide a romantic counterpoint that warms the overall look without overwhelming the gem. Because opal is more delicate than many other gemstones, careful setting choices are important, and bezel settings are often recommended to protect the edges and sides of the cabochon, while prong settings can also work if designed to shield the stone from direct knocks. Cleaning should be gentle, using a soft cloth and mild soapy water, avoiding harsh chemicals, steam, or ultrasonic cleaners that can risk damage. The fact that this stone has no enhancement means you are acquiring a genuine natural opal whose beauty comes from its formation in nature, not from treatments, which adds to its rarity and long term appeal.
