10.39 Ct. White Opal from Australia

This beautiful opaque 10.39 carat white opal measures 21.90 x 15.10 x 4.30 mm, and it is presented in a pleasing fancy shape with a tablet cut that accentuates its broad play of color. The opal displays intense color intensity, with vibrant flashes of blue and green and subtle hints of warmer tones across its surface. The body tone is characteristic of white opal, with a translucent to light opalescent base that allows the play of color to read strongly against the lighter ground. Clarity is described as opaque with minor natural potch and small internal features visible under magnification, none of which detract from the overall optical performance. The tablet cut is expertly executed to maximize the sheet of color, and the excellent polish produces a lively surface sheen that enhances the gem when set or viewed under light. This specimen originates from Australia, a provenance widely respected in the market for producing high quality opals, and the piece is an assembled doublet, a common and stable enhancement used to present thin slices of precious opal securely for jewelry use.

As a trade informed recommendation, the doublet construction is important for educated buyers to understand, because it allows a larger apparent carat weight of opal color to be offered at a more accessible price point than a solid natural opal of similar visual effect. The doublet typically consists of a thin opal layer bonded to a dark backing or support, which intensifies color contrast and display, while the tablet cut and superior polish further elevate the visual appeal. For care and setting, avoid prolonged exposure to water, extreme heat, and harsh chemicals, and consider protective bezel settings for everyday wear to protect the opal layer. From an investment and design perspective this 10.39 carat Australian white opal doublet is ideal for bespoke jewelry, collectors seeking well displayed play of color, or designers wanting a statement center stone that balances size, color, and affordability.
