5.20 Ct. Green Cabochon Jade from Burma (Myanmar)

This 5.20 carat oval green jade presents a technically disciplined cabochon execution, with precise dimensions of 14.01 x 11.90 x 3.44 mm. The cutting style is a classic domed cabochon, exhibiting an even, symmetrical profile and a well controlled apex, giving a pleasing optical continuity across the surface. The piece is opaque with medium color intensity, showing uniform color distribution and minimal zoning, characteristics that indicate a high quality preforming and selection of rough material. The thickness of 3.44 mm produces a dome height ratio of approximately 29 percent relative to the width, placing the cabochon in a medium to high dome category that maximizes surface sheen and tactile luster without compromising structural stability for bezel settings. The polish is excellent, applied through graduated abrasives and final fine grain polishing that preserves the stone s natural grain and enhances the typical waxy to slightly vitreous sheen associated with fine Burmese jade. There are no enhancements, and the origin is Burma, Myanmar, which contributes to the material s provenance and market perception.

Weight is a primary determinant of value and rarity in opaque jade, and at 5.20 carat this oval cabochon occupies a highly desirable size class for collectors and high end jewelry designers. Larger, well proportioned cabochons of untreated Burmese jade are comparatively rare because the cutting yield from quality rough is low, and maintaining uniform color and an undamaged surface while achieving a stable dome requires careful lapidary planning. The 5.20 carat mass not only commands a premium per carat relative to smaller stones, it expands practical design applications, allowing for confident use in signet rings, substantial pendants, and bespoke pieces where the visual impact of the stone s mass is essential. From a technical valuation perspective, the combination of weight, exacting cabochon proportions, medium color intensity, excellent polish, absence of treatment, and Burmese origin creates a convergence of factors that raises both market desirability and long term collectability. The Natural Gemstone Company presents this piece as a technically refined, materially significant example of classic green jade cabochon cutting, ideal for knowledgeable buyers seeking a rare, untreated specimen with measurable lapidary merit.
