1.27 Ct. Cabochon White Opal from Australia

This oval, opaque White Opal weighs 1.27 carat, and measures 8.99 x 7.14 x 3.98 mm, and is presented as a classical cabochon cut optimized for stability and color presentation. Originating from Australia, this specimen displays a multi color play within a white body tone, with medium color intensity and an overall eye clean clarity grade as evaluated at standard viewing distance. The cut is a smooth domed cabochon with symmetrical outline and well controlled dome height, attributes that were selected deliberately to balance the internal diffraction of light with the physical durability required for everyday wearable settings. The stone is untreated, no enhancement, and it carries an excellent polish that maximizes luster while preserving the opal microstructure. At The Natural Gemstone Company we catalog this gem as a White Opal, its opalescence manifesting as subtle pastel flashes and occasional more saturated flashes of red, green, and blue depending on viewing angle and lighting conditions.

Technically, the cabochon exhibits precise lapidary technique, the dome curvature following a gentle convex profile that permits optimal interaction between incident light and the regular silica sphere lattice that produces play of color. The cutter maintained a uniform thickness across the breadth of the oval, avoiding thin edges that can diminish apparent color intensity, and ensuring a proportional base thickness of 3.98 mm which contributes to both optical depth and mechanical integrity. The excellent polish is the result of progressive lapping on successively finer abrasives and final cerium oxide or tin oxide finishing, yielding a surface with minimal microabrasions and broad specular reflections without obscuring the internal spectral pattern. Clarity grading at eye level confirms absence of obvious cracks, potch interruptions, or cleavage planes, the surface and near surface appearing free from treatments such as smoke, dye, or resin impregnation, consistent with the no enhancement declaration. The medium color intensity referenced should be understood as a balance point, where the white body tone permits play of color to remain evident while avoiding the deeper body tones that would be classified separately.

For design and setting considerations this 1.27 carat oval White Opal is well suited to graduated ring centers, secure bezel settings in pendants, and protective mountings in earrings, applications where the cabochon profile and stable base thickness reduce risk of impact related damage. Given its eye clean grade and even polish, the gem will present consistently under diffused daylight and controlled studio lighting, with the best color response visible when rotated under broad spectrum illumination. When assessing comparative value factors, consider origin provenance, natural state without enhancements, and lapidary quality, all of which are favorable in this example from Australia, and all of which are aspects we document and guarantee at The Natural Gemstone Company. Recommended care is straightforward, avoid prolonged exposure to direct heat, sudden temperature shocks, and harsh chemicals, clean with mild soapy water and a soft brush, and store separately from harder gemstones to prevent abrasion. Clients seeking a gemstone with tasteful, technical specification and predictable performance in jewelry will find this cabochon a refined choice, and our team is available to provide additional magnified images, mounting recommendations, or bespoke setting services upon request.
