0.73 Ct. Multi Color Cabochon Black Opal (Dark Opal) from Australia

At The Natural Gemstone Company we present an exceptional opportunity to own a gemstone that is as rare as it is beautiful, a Black Opal also known as Dark Opal, freshly sourced from Australia and offered in truly limited quantity. This is a single opaque 0.73 carat oval shape multi color black opal, measured at 8.84 x 6.44 x 2.27 mm, expertly fashioned with a cabochon cut that enhances the stone body and the vibrant play of color within. The cutting style is cabochon, the color intensity is vivid, and the polish is excellent, with no enhancement of any kind, which means the intense hues and natural character you see are wholly authentic. For collectors and connoisseurs who understand provenance, this piece carries the unmistakable signature of Australian dark opal fields, and it is presented by The Natural Gemstone Company with the provenance and transparency that high end buyers demand.

Visually this black opal is a study in contrast and depth, offering a dynamic mosaic of green and blue flashes that appear to float above a deep, nearly black ground tone, with subtle secondary tones that shift as the stone is turned in the light. The multi color display reads like a private aurora captured within a gem, and the cabochon dome amplifies the effect, creating a sense of three dimensional color play that is both lively and elegant. The oval format is timeless and versatile, measuring a compact and wearable 8.84 x 6.44 x 2.27 mm, a size that allows for tailored settings that range from refined solitaire rings to bespoke pendant designs and refined cocktail pieces. At 0.73 carat this opal sits in a sweet spot for designers seeking a statement that remains tasteful and exclusive, a gem that will sing in a finely executed mount and become the centerpiece of a custom creation. Because there is no treatment or enhancement, every flash and patch of color is the result of natural formation and expert cutting, making this gem a pure expression of nature and craft.

Owning this Black Opal places you in an elite circle of collectors who prize rarity, natural beauty, and authentic origin, and The Natural Gemstone Company is prepared to provide a bespoke service to ensure this gem is set and presented exactly as you envision. We can advise on metal choices and mounting styles that best complement the dark body tone and vivid play of color, from warm yellow gold settings that bring out the green flashes to cool white metals that emphasize the blue and violet notes. We also offer secure private viewings, detailed handling guidance, and recommendations for long term care to preserve the polish and color intensity, and because this is an untreated Australian opal we will include full documentation of the stone details and origin. This is a single, one of a kind offering, and once it is reserved it will no longer be available, which underscores the bespoke nature of this piece and the privilege of being its owner. If you would like to reserve this opal, request additional photographs, or discuss a custom design, contact The Natural Gemstone Company to begin the process of making this extraordinary Black Opal a unique expression of your collection.
