23.47 Ct. Black Opal from Australia

Presenting a remarkable, natural Black Opal from Australia, offered by The Natural Gemstone Company, this stone is a translucent, multi color beauty weighing 23.47 carats, with dimensions of 25.80 x 20.90 x 6.70 mm. The shape is a graceful oval and it has been fashioned in a tablet cut that lays the play of color across a broad, even surface. Clarity is evaluated as eye clean at eye level, which means the gem shows no visible inclusions to the unaided eye, and the polish is excellent, resulting in a bright, satiny surface that enhances the color flashes. Color intensity is medium intense, allowing the spectrum of blue, green and occasional violet tones to appear richly but naturally, without overpowering the opal. Importantly this material has received no enhancement, and every aspect from its origin to its finish is natural and responsibly sourced from Australian fields known for producing fine Black Opals.

Visually this Black Opal is a study in deep aquatic hues, with a primary play of blue and green that shifts with movement, and areas where iridescent flashes bloom into brighter green patches and hints of indigo and violet. The tablet cut emphasizes the surface pattern, creating a mosaic like appearance where patches of color seem to float on a darker base. Because the opal is translucent rather than opaque, light penetrates and refracts within the stone, adding a sense of depth and inner glow that changes in different lighting conditions. The darker body tone typical of a Black Opal provides a striking contrast, allowing each color flash to read more vividly than it would on a lighter ground. Photos can communicate pattern and tone, but seeing the piece in hand or in natural light will best reveal the stone s play of color and its subtle internal movement, details that our team at The Natural Gemstone Company is happy to help you evaluate.

From a design perspective this 23.47 carat oval is exceptionally versatile for high end jewelry, and its size and presence make it ideal as the centerpiece for a statement ring or a luxurious pendant. The oval outline and tablet cut sit beautifully in settings that protect the stone s edges, so a bezel or a protective halo design is highly recommended for daily wear, while prong settings can work well for pieces that are worn less often. For metal choices, warm yellow gold will bring out the green and blue flashes with a rich contrast, while white gold or platinum creates a cooler backdrop that can make the blue tones sing. Consider pairing the opal with small white diamonds or white sapphires as accent stones to add sparkle without competing with the opal s natural play of color. Because this is a natural, eye clean Black Opal of significant carat weight, it lends itself to bespoke creations where the setting can be designed to both showcase and protect the stone, and where the orientation of the tablet cut can be matched to the wearer s preferred angle for maximum color display.

Caring for a natural Black Opal is straightforward, and because this material has no enhancement it responds best to gentle, practical handling. Avoid exposure to harsh chemicals, prolonged immersion in water, and sudden temperature extremes, as rapid changes can stress the opal. Clean the gem with a soft, slightly damp cloth, using only mild soap if necessary, and avoid ultrasonic and steam cleaners. When not worn, store the stone wrapped in a soft cloth or in a padded jewelry box to prevent knocks and scratches.
