13.63 Ct.Tw.Total Carat Weight Cabochon Jade Pair from Burma (Myanmar)

This pair of cabochon jades presents with precise measured attributes that appeal to technical connoisseurs, each stone weighing 6.92 carats and 6.71 carats respectively, with oval outlines measuring 14.17 by 12.16 by 4.35 millimeters and 14.13 by 12.00 by 4.06 millimeters, the close dimensional match contributes to balanced weight distribution in matched jewelry, the stones exhibit a greenish blue hue with medium color intensity, the clarity is assessed as very slightly included at normal viewing distance, and the polish is graded excellent. The material origin is Burma Myanmar, a provenance historically associated with high quality jadeite, and the specimens are offered in their natural state with no enhancement, a factor of primary importance to collectors and technical buyers who require untreated material for accurate valuation and long term stability. The cabochon form has been executed to present an even doming, optical homogeneity, and a smooth transition from girdle to dome cap, the result of controlled lapidary technique that preserves the microcrystalline interlocking structure intrinsic to jade, and the surface finish is free of polishing pitting or residual abrasions which can interfere with the stone s natural waxy to vitreous lustre.

From a lapidary and optical perspective these pieces demonstrate careful attention to cabochon geometry, the oval shaping respects the material s cleavage tendencies and minimizes stress concentrations that can lead to microfracturing during cutting, dome heights are restrained to preserve translucency while providing sufficient face curvature for pleasing light diffusion, this balance between dome steepness and thickness is critical in jade, where excessive thinning can reduce color depth and over thick domes can diminish perceived translucency. The cutters employed graduated abrasive sequences and final polishing compounds optimized for jade, typically diamond grit for preforms followed by fine diamond paste and specific polishing media adapted to the stone s surface energy, such protocols yield the observed excellent polish which enhances light transmission and the soft glow associated with fine jade. The clarity grade very slightly included signals the presence of internal textural features or minute mineral inclusions that do not detract from overall appearance at normal viewing distance, instead these internal features often contribute to the stone s character, producing subtle depth and internal scattering that augment the greenish blue tone under diffuse illumination.

Color analysis of the pair indicates uniformity in hue and tone, the greenish blue classification denotes a cool spectrum leaning between green and blue with medium saturation, this color range is sought after for its calm, oceanic character and its versatility in design, the matching demonstrates tight control over color zoning and tone, the left and right stones present consistent medium intensity across their tables with only minor natural variance, such matching is difficult to achieve in natural jade and significantly enhances suitability for symmetrical settings such as pairs in earrings or twin studs. The practical implications for setting are straightforward, the slightly different dome heights and marginal dimensional differences advise a bezel or semi bezel setting to secure both stones while accommodating slight thickness variation, bezel settings protect the girdles and are preferred for cabochon jades due to their toughness and the stone s wear characteristics, when a prong setting is considered it is advisable to design custom prongs that follow the oval outline closely to avoid pressure points and to maintain cabochon stability.

From a provenance and valuation viewpoint these Burmese jades are notable for their unenhanced status, the absence of dyeing, impregnation or surface treatments preserves natural optical properties and simplifies accurate grading, untreated Burmese origin material frequently commands premium pricing in technical markets because it provides a pure expression of the material s intrinsic properties, collectors and lapidary professionals value untreated specimens for study and for high end jewellery where long term stability is essential. The Natural Gemstone Company sources and inspects each lot under standardized gemological protocols, we recommend third party certification for buyers requiring formal documentation of origin and treatment status, typical care involves cleaning with warm soapy water and a soft brush, avoiding ultrasonic baths and harsh chemicals that can interact with surface oils or any natural residues. For technical buyers seeking precise matching, further details on cut profile, dome radius, and translucency percentages can be provided, contact The Natural Gemstone Company to request additional imagery, light transmission charts, or to arrange live inspection, these two oval cabochons provide a well executed, untreated example of Burmese jade, suitable for fine matched jewellery, study, or incorporation into bespoke pieces where material integrity and lapidary craftsmanship are paramount.
