1.63 Ct. Semi-Black Opal from Australia

This translucent Semi Black Opal from The Natural Gemstone Company is an elegant and captivating example of fine Australian opal, weighing 1.63 carat, and measuring 9.66 x 8.37 x 3.24 mm. The gem is cut in a tablet style that allows a broad surface to showcase the internal play of color, and it carries a clarity grade of very slightly included, evaluated at eye level. The color intensity is rated as intense, with flashes of green, red, and flashes of blue and violet visible as the stone is turned under light. The polish is excellent, and there has been no enhancement, preserving the natural character and value of this gem. Origin is Australia, a renowned source for some of the most desirable opals in the world, and this piece displays the depth and fire that collectors and designers seek. The combination of translucency and multi color play gives the gem a luminous presence while maintaining the subtle dark background tones that characterize a Semi Black Opal, providing contrast that enhances each color flash.

As a salesperson who works with gemstones every day, I recommend this opal for a variety of jewelry applications where its tablet cut and dimensions can be best appreciated. In a ring setting the shallow dome will sit comfortably close to the finger, offering both wearability and protection for the stone, while in a pendant the face up area will command attention and show off the vibrant color patches to best effect. The palette of vivid greens and reds contrasts beautifully with both white metals and warmer tones, so consider white gold or platinum for a crisp modern look, or rose gold for a softer, romantic glow. Because the surface is well polished and the tablet cut maximizes face up color, the stone will read larger visually than its carat weight might suggest, making it a strong choice for a feature piece. For bespoke design options The Natural Gemstone Company can work with you to source complementary accent stones, to design a protective bezel or a low profile setting, and to ensure the mounting enhances the opal rather than competing with it.

Opal care and longevity are important considerations, and this Australian Semi Black Opal will reward careful handling. Avoid prolonged exposure to harsh chemicals, perfumes, and household cleaners, and do not subject the stone to extreme temperature shocks, as opal can be sensitive to rapid change. Clean gently with a soft cloth and warm soapy water, rinse thoroughly, and dry with care before storing. Store this opal separately from harder gemstones to avoid abrasion, and consider a padded jewelry box or soft pouch for daily wear pieces. Because this piece has no enhancement and carries a high polish and intense color, periodic professional inspection is also recommended to ensure settings remain secure and to maintain the overall presentation of the gem.
