27.29 Ct. Green Cabochon Jade from Burma (Myanmar)

This specimen is a single, opaque round green jade, weighing 27.29 carats, measuring 17.93 x 17.76 x 10.02 mm, cut as a classic cabochon. The overall outline is a near perfect circle, with a well controlled dome profile producing a pleasing visual weight and balance, the cabochon displays a dark color intensity that reads as a deep, even green under standard viewing conditions, the polish is excellent, yielding a smooth reflective surface that highlights subtle internal texture rather than transparency, the base has been finished flat to facilitate secure bezel setting and to emphasize the solidity of the material, the piece is reported as no enhancement and originates from Burma Myanmar, a provenance highly regarded for fine jade specimens, The Natural Gemstone Company presents this stone as a ready to set cabochon that will perform well in substantial jewelry designs or as a collector piece for connoisseurs who prioritize natural, untreated material.

From a lapidary perspective the cutting style and execution are important to appreciate for their technical merit, the cabochon form chosen maximizes color saturation and hides internal grain that would otherwise interrupt the face up appearance in faceted cuts, the dome height and curvature have been calibrated to avoid overly steep profiles which can create weak points during setting, symmetry between the two principal axes is carefully maintained, the girdle transition to the base is smoothly radiused to reduce stress concentration when the stone is fitted into metal, the polishing sequence likely progressed through successively finer diamond laps followed by a final polish with cerium oxide or diamond paste depending on the mineralogy, the result is a mirror like finish with minimal surface distortion, lapidary details such as these are critical in cabochon work to preserve color, to minimize light leakage at the base, and to ensure the stone sits stably within a bezel or collet.

On the gemological side the piece exhibits attributes consistent with quality Burmese jade, the material presents a dense body tone and a uniformly dark green hue, translucency is effectively nil, classifying the stone as opaque which emphasizes color over brilliance, jade varieties vary in composition but Burmese sources are predominantly jadeite, jadeite typically has a specific gravity around 3.30 and a refractive index near 1.66 to 1.68, hardness for jadeite is approximately 6.5 to 7 on the Mohs scale which confers good abrasion resistance for everyday wear when properly set, there is little to no play of light given the cabochon style and the intrinsic texture of the material, inclusions in jade tend to be interlocking fibrous or granular structures rather than single crystal inclusions, this intergrowth contributes to toughness, the declaration of no enhancement is significant for collectors because many commercial jades are treated to improve translucency or color, the certified Burmese origin and natural state make this example particularly desirable for traditional collectors and high end designers.

For designers and end users the combination of weight, dimensions, and dome height suggests applications in bold rings, substantial pendants, or cufflinks where the mass and dark saturation of the stone can be shown to best advantage, the flat base and robust thickness of 10.02 mm make the stone ideal for bezel settings which cradle the perimeter and protect the dome, prong settings can be used when a controlled bezel is impractical but they require careful engineering to avoid point stress, when considering pairings with other gem materials note that White Opal offers a contrasting aesthetic, White Opal is a hydrated silica with a milky body tone that can show play of color, its lower hardness and sensitivity to sudden temperature change or harsh chemicals make White Opal better suited as an accent rather than the primary wear surface, when designing combinations of dark green jade and White Opal consider using the opal as a complementary accent set in channels or as small cabochons to introduce lightness and iridescence, The Natural Gemstone Company is available to assist with technical questions, to provide additional images under controlled lighting, and to discuss custom mounting options, we can also supply documentation regarding origin and treatment status to support appraisal and resale, for collectors and designers who value precise lapidary work and natural provenance this Burmese green jade cabochon represents a compelling balance of technical quality and visual presence.
