1.27 Ct. White Opal from Australia

This listing presents a single, opaque White Opal weighing 1.27 carat, offered by The Natural Gemstone Company. The stone is a pear shape, with exact dimensions of 12.18 x 8.01 x 2.36 mm, and it exhibits a tablet cut that emphasizes a broad, low profile table. The gem is multi color in presentation, with discrete patches and pinfire-like flashes distributed across the surface. Clarity grade is very slightly included evaluated at eye level, and overall body tone reads as a light white base. Color intensity is classified as medium light, and the surface evaluation yields an excellent polish. Enhancement is none, no treatments applied, and origin is Australia, a primary source for high quality White Opal material.

From a lapidary and gemological perspective, the tablet cut on a pear outline demands specific attention to thickness and table proportions. This tablet cut produces a shallow crown and minimal dome, which in this specimen allows the play of color to read more subtly across the face rather than concentrating in columnar flashes that are typical of higher domed cabochons. The proportions for this 12.18 x 8.01 x 2.36 mm piece are optimized to preserve weight while maintaining an even color distribution, a deliberate choice by the cutter to present a balanced multi color effect across the pear silhouette. The cut transitions around the girdle are smooth, the edge treatment is clean, and the excellent polish enhances surface luster and minimizes light scattering from microabrasions, which is essential for white opal where body translucency is limited by opacity.

Optical and structural characteristics of this White Opal account for its multi color play. The opal is composed of tightly packed silica spheres that diffract incident light, creating interference colors when viewed at variable angles. In this specimen the diffraction structure yields predominantly green to occasional red flashes set against a milky white base. The medium light intensity indicates that the diffraction events are moderately strong, suitable for pieces that require a balance between visible play of color and wearable discretion in daily light conditions. The clarity evaluation as very slightly included evaluated at eye level indicates minor internal features that do not significantly interrupt the color patches, and which are only identifiable upon direct inspection in controlled lighting. Because the material is opaque, light transmission is limited, therefore the interplay of surface polish and internal diffraction becomes the primary determinant of visual appeal, and the excellent polish on this tablet cut maximizes that interaction.

From a practical setting and design standpoint, the tablet cut and pear shape have implications for mounting and jewelry construction. The relatively low depth of 2.36 mm favors bezel or partial bezel settings that protect the shallow pavilion and maintain the integrity of the girdle, while allowing the table orientation to be optimized for the most dynamic view of the multi color play. Prong settings can be used, but they require precise seat cutting to avoid undue pressure on the thinner profile, especially near the pointed end of the pear. When orienting the gem in a design, align the long axis to encourage broad face presentation, and consider settings that permit light to interact with the stone at multiple angles to maximize the visible diffraction. For rings intended for daily wear, a full bezel with a slightly raised rim will protect the stone, whereas pendants and earrings can exploit the tablet profile to sit flush against a mounting plane for a contemporary, low profile aesthetic.

The Natural Gemstone Company provides this White Opal as a carefully selected example of Australian material that balances technical lapidary choices and gemological character. For the knowledgeable buyer who prioritizes craftsmanship, note that the cutter preserved carat weight while engineering the tablet proportions to enhance even color distribution, and that no enhancement was applied to alter the inherent optical properties. This piece is suitable for designers seeking a controlled multi color effect within a classic pear outline, and for collectors who appreciate documented origin and transparent grading. If you would like additional imaging under daylight and incandescent sources, measurement of table percentage and crown height, or guidance on recommended mounting techniques for specific jewelry applications, we can provide those details to assist in design planning and to ensure the stone performs as intended in finished work.
