5.15 Ct. Yellowish Green Cabochon Jade

This piece is a 5.15 carat oval cabochon, a finely carved jade of origin that exemplifies premium material and lapidary skill. The exact dimensions are 12.40 x 9.99 x 5.41 mm, dimensions that yield a substantial presence for a gem of this class without compromising wearability. The body color is a yellowish green with light color intensity, described in precise terms to set expectations for hue and saturation. The cabochon cutting style is carved cabochon, rather than a simple rounded dome, and the carving produces a controlled relief motif that both showcases the stone mass and preserves the integrity of the material. This is an opaque jade with an excellent polish and important for discerning collectors the stone has received no enhancement, a condition that directly supports its premium valuation. The provenance points to a source revered for producing jadeites of notable texture and color, and we are presenting this example as a high quality specimen suitable for collectors and designers who prioritize natural state and precise craftsmanship. From a metrological perspective the 5.15 carat weight translates to a mass of 1.03 grams, calculated on the standard carat unit of 200 milligrams. When considered alongside the physical dimensions the mass indicates a dense material, consistent with high quality jadeite which typically exhibits specific gravity values near 3.30, and distinct from nephrite with lower specific gravity near 2.95. The combination of mass and volume therefore becomes a diagnostic tool, reinforcing the identification and suggesting minimal internal porosity or extensive fissuring that would otherwise reduce mass for given external dimensions. The dome height of 5.41 mm relative to the length of 12.40 mm yields a dome to length ratio of approximately 0.44, a relatively pronounced profile that emphasizes the carved relief while maintaining structural thickness at the pavilion. The thickness provides a secure blank for the carver, allowing the creation of shallow three dimensional motifs without compromising stability, and the resulting cabochon maintains even wall thickness and symmetry, attributes that are measurable indicators of careful preform planning and execution. Color and surface quality are essential determinants of both aesthetic and market value for opaque jade, and this piece presents a uniformly distributed yellowish green with light color intensity and subtle evenness of tone. The saturation is restrained, which in jade terminology often appeals to collectors who prefer elegance over aggressive chroma, and the hue balance avoids abrupt zoning or localized dark patches. The carved cabochon surface exhibits an excellent polish, producing a consistent waxy to slightly vitreous luster when examined under diffuse light, a finish that maximizes the material response without creating the artificial sheen associated with some enhancements. Close examination reveals crisp definition along carved ridges and smooth transitions across the curved planes, evidence of fine abrasive progression and controlled lapidary work. There is no indication of dyeing, resin impregnation, or thermal modification, factors that we document and verifies, and the absence of enhancement preserves both the intrinsic appearance and the long term value for sophisticated buyers who require unaltered material. Provenance carries technical implications, both historical and gemological, since high quality jadeites are known for compact texture and favorable crystallinity that respond well to carving and polishing. This example benefits from those material attributes, and the measured properties discussed earlier support a classification that aligns with premium jadeite categories when unenhanced status is a priority. For practical application this cabochon is well suited to secure bezel settings, custom carved mounts, and pieces where the dome is visible and can be appreciated as a sculptural element, and the 5.15 carat weight ensures a wearable scale that commands presence without excessive bulk. We stand behind the technical description and can provide additional documentation, high resolution imaging, and guidance for setting and certification upon request. For buyers who evaluate gemstones with an emphasis on quantifiable traits such as carat weight, dimensional ratios, material density, and verified enhancement status, this carved jade cabochon represents a harmonious convergence of premium substance and accomplished craftsmanship.
