1.28 Ct. Cabochon White Opal from Australia

This pear shaped White Opal from The Natural Gemstone Company weighs 1.28 carats and measures 11.96 by 7.77 by 2.57 millimeters, presenting an opaque body with a classic cabochon profile. The gem has been fashioned as a smooth domed cabochon rather than a faceted stone, the dome height carefully balanced to optimize play of color while maintaining a stable setting profile for jewelry applications. Symmetry across the pear outline is precise, the termination at the point executed to minimize stress concentrations when set. Clarity is graded as very slightly included at eye level, with only minor internal features that do not interfere with the overall visual effect or structural integrity. The polish is excellent, producing a uniform luster across the dome and crisp transitions between surface and girdle, which enhances light entry and the effectiveness of internal diffraction. No treatments or enhancements have been applied, and the opal is a natural Australian specimen, confirming its provenance and stability.

Optical characteristics are consistent with a high quality White Opal, exhibiting a multicolor play of color with predominantly green and red flashes, and intermittent blue and orange contributions under standard viewing conditions. Color intensity is assessed as medium, providing a balanced contrast against the pale body tone that is characteristic of White Opal, and producing a vivid yet wearable appearance. The microstructure of silica spheres is evident in the way color shifts with viewing angle, yielding discrete patches and linear flashes rather than uniform sheen, which collectors and designers will recognize as desirable for dynamic visual interest. Given the gemology and dimensions, this opal is well suited to pendant and drop earring designs where the pear silhouette and cabochon dome can be showcased without excessive prong exposure. For secure mounting we recommend a classic bezel setting or a low profile prong design that supports the point and protects the crown, ensuring long term stability. The Natural Gemstone Company presents this opal with full disclosure of origin, enhancement status, and measured values, appealing to buyers who prioritize precise specification and natural provenance.
