1.63 Ct. Semi-Black Opal from Australia

Presenting a remarkable Semi Black Opal offered by The Natural Gemstone Company, a translucent, multi color oval weighing 1.63 carats, with precise dimensions 9.66 x 8.37 x 3.24 mm. This gem has been fashioned in a tablet cut that favors broad, lively flashes of color, and it displays intense color intensity across a balanced mix of greens, reds, and subtle blues that sing as the stone moves in light. Clarity is graded very slightly included at eye level, which means small internal characteristics are present but do not distract from the overall brilliance. The polish is excellent, and importantly this opal is completely natural with no enhancement, sourced from reputable deposits in Australia. For buyers who appreciate authenticity and long term value, a solid, untreated Semi Black Opal like this stands apart from assembled stones that mimic opals but lack permanence and natural depth.

When comparing this gem to other opal types and market alternatives, several decisive advantages become clear. Versus common white opals, a Semi Black Opal carries a darker underlying tone that amplifies play of color, resulting in more vivid and dramatic flashes at comparable sizes. Compared to black opal from the highest grade fields, this piece provides exceptional color intensity at a more accessible price point, while still offering that coveted depth of color that collectors and designers seek. Against doublets and triplets, which layer thin opal slices over backing and top with a cap, a solid tablet cut opal like this is superior in longevity, stability, and authenticity, since no glue layers or glass caps can dull or separate over time. Versus synthetic or lab grown opals, this natural Australian gem exhibits organic color patterns and a density of color that is difficult to replicate artificially, and the absence of treatment enhances resale value and collector interest. The very slightly included clarity is typical for natural opals of this character, and in practice these inclusions add to the stone character without interrupting the intense play of color that makes the gem stand out under real world lighting.

For practical use and care, this Semi Black Opal is exceptionally versatile and ideal for a feature stone in rings or pendants where the tablet cut can be seen and admired, and where the size 9.66 by 8.37 mm is perfect for a striking center. Because opal sits lower on the Mohs hardness scale than many gemstones, The Natural Gemstone Company recommends settings that offer protection, such as bezel or halo styles, and the use of precious metals that frame the gem securely. Avoid prolonged exposure to harsh chemicals or extreme heat, and clean gently with a soft cloth and mild soapy water to preserve the high polish. Choosing this opal means selecting a single piece that will outperform common market substitutes in both aesthetic appeal and long term value, since it is a solid, untreated Australian Semi Black Opal with intense play of color and excellent polish.
