1.09 Ct. Cabochon White Opal from Australia

One opaque White Opal weighing 1.09 carat is presented, cut into an oval cabochon with dimensions of 9.10 by 7.07 by 3.39 millimeters. The gem exhibits a classical cabochon silhouette, with a smoothly domed top and a well controlled pavilion that maintains a pleasing profile when set. Origin Australia is documented for this specimen, and no enhancement has been applied. The Natural Gemstone Company offers this stone as a natural, unenhanced example of the White Opal category, suitable for collectors and designers seeking a genuine Australian material with stable visual character.

The physical measurements indicate a balance between face dimensions and depth, providing a practical table area on the dome while preserving sufficient thickness for secure mounting. The cabochon cut has been executed to present an even curvature that maximizes surface luster, and the polish is graded excellent, producing a reflective, glass like finish across the dome. Clarity has been evaluated at the eye level and reported as eye clean, meaning that under normal unaided visual inspection there are no significant inclusions or fractures that detract from the gem appearance. The specimen is opaque, with a near colorless base tone that reads as a soft white background, permitting internal opalescence to be visible at oblique angles.

Optical behavior is consistent with quality White Opal from Australian deposits, showing subtle internal iridescence and intermittent flashes of color when viewed under directional lighting. The play of color is modest rather than exuberant, which is characteristic of many white opals and can be appreciated as a gentle, diffuse shimmer rather than bold patches. This restrained optical presentation makes the gem versatile for a range of jewelry applications where a refined, understated opalescence is preferred. No treatments or enhancements have been performed on this stone, ensuring that the observed optical effects and body properties are intrinsic to the material as extracted and finished.

Practical considerations for use and care are straightforward. The cabochon profile and the 3.39 millimeter thickness support secure bezel or prong settings designed to protect the dome, and the nearly neutral body color allows for pairing with a variety of metal tones. As with all opals, routine care involves avoiding prolonged exposure to strong heat or rapid temperature change, and limiting contact with harsh chemicals to preserve surface polish.
