22.31 Ct. Multi Color Black Opal from Australia

One piece described, one translucent 22.31 carat oval multi color opal, dimensions 25.00 by 18.00 by 5.27 millimeters, tablet cut, identified as a Black Opal from Australia, is presented with full gemological particulars. The gem carries an eye clean clarity grade when evaluated at normal viewing distance, indicating no inclusions visible to the unaided eye under standard lighting conditions. Color intensity is classified as intense, and the surface polish is graded excellent, reflecting a high degree of lapidary finish consistent with the tablet style. No enhancements have been applied to this specimen, confirming its natural state as delivered from origin to client, and its combination of weight, dimensions, and finish make it suitable for a variety of jewelry applications where a strong play of color on a dark body tone is desired.

Visually the stone exhibits the characteristic contrast of a true Black Opal, with a predominantly dark body tone that serves to accentuate vivid, multi color play. Observed color flashes are most prominent in green and blue ranges, appearing as bright veins and patches across the dark background, with areas of more diffuse chromatic movement creating depth and complexity. The translucent nature of the opal allows some light transmission at the tablet edges, which contributes to internal luminescence and enhances the perceived intensity of color when viewed at varying angles. The tablet cut presents a shallow, broad profile that favors face-up color presentation and a stable curvature, maintaining color orientation in most mounting styles while minimizing the risk of chipping that can occur with thinner cabochons.

From a practical design and setting perspective, the 25 by 18 millimeter oval tablet and 5.27 millimeter depth provide a substantial face-up area that is suitable for rings, pendants, or statement pieces. The tablet format, with its broad surface and low dome, is well suited to bezel settings that protect the stone perimeter while showcasing the play-of-color across the top surface. Prong settings are also possible provided the mounting is designed to support and protect the stone edges, and consideration should be given to allowing light to reach the face to maximize iridescence. The gem’s dark body tone and intense green and blue flashes pair elegantly with yellow gold for warm contrast, with white gold and platinum providing a more neutral frame, and silver offering a contemporary option. Because the visual appeal of Black Opal is highly dependent on orientation, the final design should allow for the stone to be set with its best color-bearing face foremost.

Care and handling recommendations reflect the natural properties of opal as a hydrated silica material that requires considerate maintenance to preserve color and stability. Avoid exposure to sudden temperature changes, harsh chemicals, prolonged immersion, and ultrasonic or steam cleaning methods, which can damage structure or surface polish. Clean with a soft cloth and mild soapy water, rinse gently, and dry immediately. Store the opal separately from harder gemstones to prevent abrasion and consider a padded compartment or a fabric-lined box to mitigate impact risk. Although this stone is eye clean, regular inspection of the mount and setting is advised to ensure secure retention and to protect the tablet edges from knocks and abrasion. The Natural Gemstone Company provides these technical and care particulars to support responsible handling and long term enjoyment of this Australian Black Opal.
