27.29 Ct. Cabochon Jade from Burma (Myanmar)

This round green jade presents as a substantial and well proportioned cabochon, weighing 27.29 carats and measuring 17.93 x 17.76 x 10.02 mm, the equivalent of approximately 5.458 grams, sourced from Burma Myanmar and offered by The Natural Gemstone Company. The specimen is opaque in nature with a dark color intensity that reads as a deep rich green under standard daylight conditions, and the surface has been brought to an excellent polish. The material is reported as untreated with no enhancement, which preserves the natural internal texture and optical qualities typical of Burmese jade. Evaluation of clarity was carried out at eye level, and the stone is classified as eye clean, indicating that any internal features are not readily visible without magnification, which supports its suitability for prominent jewelry settings where surface uniformity and depth of color are primary aesthetic goals.

The cabochon cut adopted for this piece has been executed with attention to classical gemstone proportions, the dome height and curvature optimized to enhance apparent color saturation and surface luster. The round outline is symmetrical to within the tolerances expected for a hand finished cabochon, and the pavilion has been shaped to provide stable mounting surfaces for a variety of bezel and collet settings. The polished dome yields uniform specular highlights and a satiny to vitreous luster that is consistent across viewing angles, a result of tight stone cutting and controlled polishing stages. The dense body color benefits from the convex geometry, as the dome concentrates light within the near surface material, creating a perception of greater depth than a low profile cut would provide. The measured thickness of 10.02 mm contributes to the substantive feel of the piece and supports secure setting options without compromising the cabochon silhouette.

From a gemological and craftsmanship perspective, the combination of a dark body color, opaque translucency, and eye clean clarity indicates a high quality of rough selection and finishing. The absence of enhancement is an important technical attribute, as many commercial jades undergo treatments to alter translucency or color, but this specimen retains its native chroma and microstructure. The internal fabric typical of Burmese jadeite contributes exceptional toughness and resistance to fracturing, which is advantageous in fabrication and for long term wear. The excellent polish is evidence of controlled lapidary techniques, including progressive abrasive sequences and final polishing compounds selected to minimize surface haze and to maximize specular reflection. For mounting considerations, the stone’s round shape and robust thickness allow for deep bezels and flush settings alike, and standard practices for adhesive or mechanical securing are applicable. Routine care guidelines include avoiding sudden thermal shock and harsh chemicals, while mechanical abrasion should be minimized to preserve the polished surface.

For comparative and design context, information is provided regarding White Opal, which is a distinct material frequently considered alongside jade in jewelry design due to its complementary tonal qualities. White Opal is characterized by a light body tone that ranges from near colorless to milky white, and in precious examples, it exhibits play of color with flashes of spectral hues at various viewing angles. Unlike the dark saturated body of this Burmese jade, White Opal tends to offer internal iridescence against a pale ground, and its optical behavior derives from a microstructure of silica spheres rather than the interlocking mineral grains of jade. From a setting and care perspective White Opal is generally more sensitive to impact and desiccation than jade, and therefore design pairings should accommodate differential hardness and stability. When considering combinations, the dark green mass tone of this jade provides a durable and visually stable counterpoint to the ephemeral color play of White Opal, permitting designers to create contrastive compositions that leverage the strengths of both materials. The Natural Gemstone Company can provide additional technical sheets and matched pairs for designers who require calibrated color relationships, documentation of provenance, and untreated material certification for both jade and White Opal.
