1.72 Ct. Black Opal from Australia

Introducing a rare and striking Black Opal offered by The Natural Gemstone Company, a beautiful opaque cushion shape multi color opal weighing 1.72 carats, with precise dimensions of 15.02 x 6.78 x 2.17 mm. This gem has been fashioned in a tablet cut to maximize the surface area that displays color, and it has been polished to an excellent finish that allows light to play across its surface with minimal obstruction. The body tone is true to the Black Opal category, providing a deep backdrop that intensifies the apparent brightness of the red, blue, green and purple flashes that appear as you move the stone. This opal has vivid color intensity, with broad flashes that travel across the tablet face, and important to note, there has been no enhancement applied to this gem, the color and polish are entirely natural, coming directly from an Australian source known for producing some of the finest opals in the world.

Visually, this opal reads as a dramatic canvas of color, with red fire that appears in patches and ribbon like streaks of electric blue and teal that dance across darker fields, creating depth and movement that change with every tilt. The cushion shape gives a softly rounded outline that wears comfortably, and the tablet cut presents a flat smooth face that makes the color pattern easy to admire in settings that allow light to reach the surface. At 15.02 mm long and 6.78 mm wide, it is elongated enough to make an elegant pendant centerpiece, yet narrow enough to sit gracefully in a bespoke ring design. The 2.17 mm thickness is ideal for secure bezel or prong settings while keeping the visual profile low enough for everyday wear, and because this stone is opaque, it offers a dense, portrait like quality to the color patches, which translates beautifully into jewelry that evokes modern sophistication or classic refinement.

From the perspective of quality and provenance, this Black Opal comes from Australia, the preeminent source for opal specimens prized by collectors and designers around the world, and The Natural Gemstone Company stands behind its authenticity and descriptive accuracy. The absence of enhancement is a significant quality marker for opal buyers, because treatments such as dyeing or smoke treatments alter the natural character of the stone, and their absence means you own a gem whose beauty is entirely geological, formed over millions of years. The excellent polish we applied reveals the underlying structure and sheen of the opal, and the vivid color intensity is a testament to both the rough material and the cutter who chose the tablet cut to maximize play of color. For those who appreciate gemological detail, the weight of 1.72 carats is substantial for a tablet cut Black Opal of these proportions, balancing presence with wearability, and the cushion profile creates a pleasing silhouette whether set vertically or horizontally.

In practical terms, this opal is versatile for custom design or ready to set into a signature piece, and our recommendations at The Natural Gemstone Company include protective settings that shield the edges while exposing the face to light, such as a low bezel with a slight lip or a secure prong setting combined with a protective gallery. Care for a natural Black Opal involves guarding against harsh chemicals, prolonged exposure to heat, and strong knocks, while cleaning gently with a soft cloth and mild soapy water when needed. If you seek a one of a kind center stone that combines collectible pedigree with wearable size, this 1.72 carat Australian Black Opal offers vivid color, an excellent polish, and natural integrity with no enhancements, making it an exceptional candidate for engagement jewelry, a luxury pendant, or a curated collection.
