3.68 Ct. Semi-Black Opal from Australia

Thank you for considering this exceptional Semi Black Opal from The Natural Gemstone Company, this is an opaque multi color opal weighing 3.68 carats, cut into a graceful oval shape with exact dimensions of 12.75 x 10.23 x 4.38 mm. The gem is fashioned in a tablet cut that preserves maximum play of color while offering a comfortable low profile for many jewelry designs. Clarity has been graded as slightly included when evaluated at eye level, which is common for natural opals and adds character without detracting from the stone s optical performance. Color intensity is intense, the polish is excellent, and importantly there has been no enhancement, assuring you of a natural Australian origin and an honest gem that will age gracefully with proper care.

Visually this Semi Black Opal is a vivid study in contrast, the darker body tone acting as a stage for lively flashes of green and blue streaks that sweep across the surface, punctuated by unexpected flashes of orange and red that appear as you rotate the stone. The tablet cut creates broad planes of color rather than tiny pinpoints, so the play of color reads boldly at a glance and rewards close inspection with shifting patterns and depth. The opal s semi black character deepens the greens and blues while allowing warm tones to emerge in pockets, giving a multi spectral effect that feels both dramatic and refined. For settings I recommend choices that respect the stone s flat profile and showcase the color, classic bezel settings and flush mounts provide security and a modern aesthetic, while low profile prong settings can emphasize the oval outline. For metal pairings consider warm 18 karat yellow gold to amplify orange and red flashes, or cool white gold and platinum to enhance the electric greens and blues, and for a bold contemporary look consider oxidized silver or black rhodium to complement the semi black body tone.

As a selling point from The Natural Gemstone Company this opal is a natural, untreated piece from Australia, ready for custom or ready to mount work, and it is ideal for a statement ring, a pendant that sits flat against the chest, or a pair of matching pieces for cuffs or a bespoke brooch. Care is straightforward, opals are best protected from sudden temperature change and harsh chemicals, clean gently with a soft cloth and mild warm water, avoid ultrasonic cleaners and steam, and store separately from harder gems and metals to prevent scratches.
