8.57 Ct. White Opal from Australia

One exquisite White Opal from The Natural Gemstone Company, weighing 8.57 carat, oval shape, translucent, multi color play, dimensions 18.13 x 13.87 x 5.73 mm, tablet cut, clarity grade included evaluated at eye level, medium intense color intensity, excellent polish, no enhancement, origin Australia. This gem is a classic Australian White Opal with a soft body tone that allows internal play of color to float through the stone, making it a lively and wearable specimen, while remaining natural and untreated. The tablet cut gives a broad, gently domed surface that enlarges the visible color patches and provides a smooth field for the opal to show blue and green flashes, with hints of warmer tones when viewed at certain angles. As a salesperson and gem enthusiast I put the technical facts first so you can immediately see the authenticity and exact specifications of this fine opal.

Visually this piece reads as a refined study in subtlety, the translucent body allowing delicate spectral colors to migrate across the surface as the stone moves. You will notice mainly cool tones of aqua and teal, punctuated by fleeting ribbons of pink and soft orange that become more apparent under directional light. The tablet cut produces a slightly flattened dome that emphasizes large, graceful flashes rather than tight pinfire patterning, and the excellent polish gives a satiny surface that enhances the opal glow. The included clarity grade means there are natural internal characteristics visible at eye level, which are common in opals and often contribute to their character and story. These internal features do not detract from the gem when set thoughtfully, in fact they can add depth and interest when the stone is examined closely under magnification or in hand.

This White Opal is particularly well suited to a number of jewelry applications owing to its size and shape, most especially as a central pendant, a statement ring with a protective bezel setting, or a bespoke brooch that showcases its oval silhouette. The dimensions 18.13 x 13.87 x 5.73 mm translate to a comfortable presence on the wrist or neckline without feeling oversized, and the weight of 8.57 carat gives substance without overwhelming a design. For setting recommendations I generally suggest an open back or a light enhancing foil where appropriate to boost brightness, however because this opal is untreated and prized for its natural translucency, a simple polished bezel or a low profile prong mount often preserves the clean aesthetic and protects the edges. As with all natural opals, avoid high heat, sudden temperature changes, and harsh chemicals, and clean gently with warm water and mild soap and a soft brush, never with steam or ultrasonic cleaners.
