8.05 Ct. Boulder Opal from Australia

One beautiful opaque 8.05 carat pear shape multi color opal from Australia awaits, a genuine Boulder Opal with dimensions of 21.90 x 9.70 x 4.50 mm, expertly fashioned in a tablet cut to showcase its surface play and structural strength. This stone displays intense color intensity with lively flashes that sweep across the surface as it catches the light, revealing vibrant greens, electric blues, and fiery reds that dance against a deep, dark matrix. The tablet cut gives the gem a sleek, flat top and a thin profile that emphasizes the color patches and mosaic like pattern unique to boulder material, while the excellent polish enhances each color flash and provides a smooth surface ideal for close inspection and comfortable wear. There is no enhancement to this opal, it is natural and untreated, which means you are acquiring a raw expression of nature preserved by geology and skilled cutting, a piece that will age and respond to light in ways synthetic or treated stones cannot replicate.

For design and setting, this pear shape offers incredible versatility and presence, the elongated 21.90 mm length making an elegant pendant centerpiece or a bold statement ring, while the tapered point can be oriented up or down depending on the design language you prefer. As a Boulder Opal, the stone typically retains portions of its ironstone matrix, which adds stability and a rich backdrop to the color play, allowing for creative bezel work or partial bezel and prong combinations that protect the edges without obscuring the most colorful areas. The tablet cut and low profile invite settings that sit close to the skin, which is especially desirable for pendants and rings that are worn daily, and the excellent polish ensures minimal friction against settings. I recommend a secure bezel for rings destined for frequent wear, and an open back or halo setting for pendants that will allow light to penetrate and animate the colors even more. Because this opal is opaque and carried on a natural matrix, it is less sensitive to light and moisture changes than crystal opal, yet like all opals it benefits from thoughtful mounting and occasional gentle cleaning with a soft cloth and mild soap and water.
