2.97 Ct. Green Cabochon Jade from Burma (Myanmar)

This listing presents a single translucent green jade, round in outline, weighing 2.97 carats, with precise dimensions of 9.84 by 9.83 by 3.66 millimeters, cut as a cabochon and graded as very slightly included at eye level, with medium color intensity, excellent polish, no enhancement, and an origin of Burma Myanmar, supplied and authenticated by The Natural Gemstone Company. The combination of the cabochon profile and the gemstone material properties yields a visual character that reads as both luminous and restrained, the surface offering crisp specular highlights while the body transmits soft, layered light from within. Measurements are taken across the girdle plane and from base to crown, the near perfect round symmetry and the uniform dome height of 3.66 millimeters produce a balanced optical path for incident light, allowing the stone to demonstrate a consistent luminous field when examined under directional illumination. Clarity observations recorded as very slightly included at eye level indicate that routine viewing does not reveal significant disruption to light flow, the minor internal features instead contributing to micro contrasts that enhance the stone sense of depth without degrading transparency.

At the mineralogical level this Myanmar jade is composed of jadeite, a sodium aluminum silicate with a tightly intergrown microcrystalline to fibrous aggregate structure, a fabric that is central to the way the material interacts with light. Jadeite typically exhibits a refractive index in the vicinity of 1.65 to 1.68, a low to moderate birefringence, and a specific gravity around 3.30, values that place it in a material class where light is transmitted and scattered rather than undergoing the multiple sharp internal reflections characteristic of high refractive index faceted gemstones. The interlocking granular crystals scatter light at a sub millimeter scale, producing subsurface diffusion and a so called greasy to waxy luster that reads visually as a soft, viscous glow. Those microscopic grain boundaries and oriented fibrous components work together to create localized refractive discontinuities, which when illuminated form numerous faint reflection sites that collectively register to the eye as a delicate, lively sparkle.

The cabochon cut is deliberately chosen to amplify the intrinsic optical behavior of the jade, with the dome geometry converting incident beam angles into internal scattering trajectories that maximize the perception of depth and inner light. The generous dome height relative to diameter in this specimen provides an extended optical path length, so photons entering the crown traverse more material and undergo multiple scattering events, then emerge as softened highlights or focused bright points where internal interfaces act as retroreflective micro surfaces. The excellent polish contributes importantly, by increasing the efficiency of surface reflection and reducing stray surface diffusion, this creates high quality specular highlights that contrast against the diffuse inner glow, a duality that our experienced clients describe as sparkle despite the absence of faceted brilliance. Because the stone is translucent rather than fully transparent, light penetration is sufficient to reveal tone and internal structure, yet the scattering remains high enough to break up light into a complex field of micro reflections, the result being a three dimensional look that changes character with viewing angle and light source, exhibiting both broad luminous zones and tape like or pinprick highlights when viewed with directional spot lighting.

From a craftsmanship and practical perspective the piece offered by The Natural Gemstone Company is optimized for fine jewelry use, the cabochon being well centered and symmetrical for bezel or low profile prong settings, the durable interlocked structure of jadeite providing excellent toughness for everyday wear, and the unenhanced state preserving natural color and internal texture for collectors who prioritize provenance and untreated material. The medium color intensity is evenly distributed across the table and girdle area, with very slight inclusions adding character rather than detracting from optical performance, and the excellent surface polish assures minimal surface wear during setting and handling. For designers and connoisseurs seeking a gem whose light behavior is rooted in mineral structure rather than surface faceting, this 2.97 carat Burmese jade cabochon offers a unique form of sparkle, one defined by depth, layered scattering, and crisp surface luster, a combination that reads as refined and natural in finished jewelry and as technically compelling under gemological examination.
