1.72 Ct. Semi-Black Opal from Australia

This semi black opal from Australia offered by The Natural Gemstone Company is a striking, translucent multi color specimen weighing 1.72 carats, with dimensions of 13.15 x 6.13 x 3.22 mm, presented in a pleasing cushion shape and finished with a tablet cut. The gem displays a vivid color intensity and an excellent polish, attributes that allow its internal play of color to express itself with clarity and liveliness, and it has been assessed as very slightly included evaluated at eye level, a clarity grade that indicates minor natural inclusions visible only upon close inspection and that do not detract from the overall beauty. There has been no enhancement applied to this opal, a pure declaration that ensures you are acquiring a natural gem in its authentic state, and its semi black classification places it in a desirable category that balances the dramatic color contrast of black opal with the luminous depth of lighter opal bodies, producing an alluring effect under a range of lighting conditions. The tablet cut emphasizes broad, horizontal flashes of color along a relatively thin profile, making it ideal for designs that call for a low dome and wide surface, and the cushion outline gives the stone a classic and versatile silhouette that works equally well in rings, pendants, and bespoke pieces.

When you view this opal in person the first impression is one of moving color, the palette leaning toward bright greens and cool aquas with hints of violet and a subtle underlying sheen that shifts as you tilt the stone, a dynamic that photographers often capture only partially due to the opal sensitivity to angle and light. The tablet cut enhances large, patchy patterning rather than pinfire specks, so you will notice expansive areas of color that can be set to display a dominant flash when mounted flat or to reveal layered color transitions when elevated slightly above the setting. With its vivid color intensity and translucent body tone, this semi black opal offers designers and collectors a flexible canvas, capable of appearing bold in a simple bezel or ethereal in a delicate halo, and it pairs beautifully with warm metals like rose gold to bring out the green tones, and with white gold or platinum to highlight the cooler blues and violets. Because the stone is tablet cut and relatively thin compared to faceted gems, careful attention to protective settings is recommended, and a low bezel or a recessed prong design will both protect the edges and allow the opal to display its full range of fire while minimizing exposure to knocks and abrasion.

Purchasing this Australian semi black opal from The Natural Gemstone Company means acquiring a natural, untreated gem with excellent polish and an assured provenance, attributes that contribute to both emotional and investment value for collectors and designers alike. For care we recommend avoiding harsh chemicals and extreme temperature shocks, storing the opal separately from harder stones to prevent scratching, and removing the jewelry before heavy impact activities, simple measures that will preserve the polish and the integrity of the play of color over decades. If you would like assistance with custom mounting ideas, a suggested metal choice, or a CAD mockup for a ring or pendant, our team is happy to provide recommendations tailored to the tablet cut and cushion outline to ensure the stone sits securely while showing maximum color.
