2.43 Ct. Semi-Black Opal from Australia

This translucent Semi Black Opal from The Natural Gemstone Company is a finely finished collector gem, weighing 2.43 carats, and presenting a cushion shape that measures 10.01 x 9.39 x 3.59 mm. The piece has been fashioned with a tablet cut that emphasizes a broad face and creates an even surface for the play of color to work across. Clarity is graded as very slightly included when evaluated at eye level, a quality grade that allows the gem to maintain exceptional visual appeal and durability for settings with some protection. Color intensity is rated as intense, and the polish is excellent, producing a smooth bright surface that accentuates the internal fire. Enhancement status is none, this opal is natural and untreated, and its origin is Australia, a source renowned for producing some of the finest opals in the world.

Visually this Multi Color opal displays deep oceanic blues and bright neon greens that shift and merge as the stone moves, giving a lively and dramatic play of color that reads as vivid patches and streaks across the tablet face. Against the darker body tones typical of a Semi Black Opal these colors pop with strong contrast, yielding that sought after depth and vitality that collectors and designers prize. Translucency allows light to penetrate and interact with the internal structure, creating layers of color that appear to glow from within. The tablet cut enhances broad flash and makes those green and blue color patches more readable at a glance, while the cushion outline offers a classic softened silhouette suitable for modern and vintage inspired settings alike.

For jewelry use this 2.43 carat cushion Semi Black Opal is ideal for a centerpiece in a ring, a pendant, or a statement pair of earrings, depending on design choices and matching stones. Its dimensions pair well with custom bezel work that will protect the girdle and the tablet top, and the very slightly included clarity grade suggests secure settings rather than open edge prongs for daily wear. I recommend protective designs such as a low profile bezel or halo setting to both showcase the intense play of color and reduce the risk of chips to the tablet edges. For care clean with a soft damp cloth and avoid ultrasonic cleaners, harsh chemicals, and extreme temperature changes, and avoid prolonged exposure to high heat or drying agents to preserve the opal hydration and stability. When setting in metal choose options that complement the blue and green flash, such as 18 carat yellow gold for warm contrast, white gold or platinum for a contemporary look, or rose gold for a softer, vintage tone.
