0.90 Ct. Cabochon Semi-Black Opal from Australia

As a gemstone specialist at The Natural Gemstone Company, I take great pleasure in introducing this exceptional semi black opal, a translucent multi color gem that captures attention at first glance. This pear shape opal displays a refined elegance that suits both classic and contemporary designs, and its smooth cabochon cut enhances the lively internal fire that opals are prized for. The soft teardrop silhouette is flattering in pendants and drop earrings, and it lays beautifully in custom rings where the play of color can be showcased to its fullest. I describe this gem with confidence because I handle gemstones daily, and I can say that this piece stands out for its balance of size, color, and overall finish, traits that discerning collectors and designers appreciate.

This opal is one single stone, weighing 0.90 carat, and measuring 12.50 x 4.60 x 2.76 mm, pear shape, cabochon cut, clarity grade very slightly included evaluated at eye level, intense color intensity, and excellent polish. The type is Semi Black Opal, which means it offers darker body tone characteristics that make the play of color appear more vivid, while retaining a degree of translucency that allows light to interact within the stone for luminous depth. There is no enhancement, and the origin of this opal is Australia, a source renowned for producing outstanding opals with stable properties and captivating color patterns. The proportions and cabochon dome have been optimized to show off the color patches and flashes, and the clarity is clean to the eye, with any natural inclusions being minimal and contributing to the stone character rather than detracting from its beauty.

Visually the stone displays a lively spectrum of reds, pinks, greens, and flashes of blue, which seem to float beneath the surface when the stone is tilted, creating a sense of motion and life. The translucent base permits a soft glow that blends with the brighter color flashes, giving the gem a painterly appearance, as if miniature auroras are trapped inside. The pear shape encourages a directional play of color that will catch attention when set vertically in a pendant, and laid horizontally it provides a graceful sweep across the finger in a ring. The intense color intensity ensures the colors remain strong under varied light, from daylight to artificial illumination, and the excellent polish gives a glass like finish that enhances both brilliance and wearability. As a semi black opal each color note is offset by a deeper tone, which adds drama and contrast without compromising the gentle inner glow that opal lovers treasure.

Choosing this opal from The Natural Gemstone Company means acquiring a gem with documented attributes and provenance, and the assurance that no treatments have been applied. For care I recommend avoiding harsh chemicals and extreme temperature changes, storing the opal separately to prevent abrasion, and occasional gentle cleaning with a soft cloth and mild soapy water, followed by thorough drying. This opal is ideal for a bespoke commission, a special anniversary piece, or as a highlight in a curated collection, and its modest carat weight combined with striking optical performance makes it a versatile and valuable selection.
