24.69 Ct. Green Jade from Burma (Myanmar)

This green jade disc began its story millions of years ago within a dynamic convergent margin in what is today Burma Myanmar, where oceanic lithosphere descended beneath continental blocks and generated sustained high pressure metamorphism. Under conditions of elevated pressure and relatively low temperature, silica rich fluids migrated through fractured basaltic protoliths and sedimentary interbeds, facilitating metasomatic reactions that concentrated sodium and aluminum into discrete pyroxene frameworks. The jade material in this piece crystallized as a fine grained, interlocking aggregate of jadeite crystals, a microstructure that imparts exceptional toughness and a homogenous opacity at the macroscopic scale. Trace element incorporation occurred contemporaneously, chromium and iron substituting into the M1 and M2 sites of the pyroxene structure, producing the characteristic green hue of this specimen. Over subsequent tectonic uplift and erosional cycles, the jade survived mechanical transport and chemical equilibration, arriving at a state of relative compositional stability that permitted modern extraction in Myanmar. The geological history is recorded in the stone as subtle color zoning and discrete mineral inclusions, features that experienced observers can read as indicators of provenance and formation environment.

This example is one beautiful opaque 24.69 carat round shape green jade, presenting precise dimensions of 24.96 x 24.82 x 3.60 mm, a mass and geometry that reflect both the original boulder segmentation and the lapidary strategy employed. The material shows a medium color intensity, a balance between chromophore concentration and the scattering effects of the microcrystalline fabric, producing a saturated yet not overly dark green that retains surface luster. Because the piece is opaque rather than translucent, assessment of color grade relies on surface tone and the distribution of pigment bearing zones, rather than on light transmission characteristics. Physically, the specimen conforms with expected jadeite metrics, exhibiting a specific gravity in the range consistent with pyroxene based jade, and a Mohs hardness near 6.5 to 7 coupled with exceptional toughness due to the interlocking granular habit. The flat, coin like profile with a thickness of 3.60 mm demands careful consideration for mounting, as the shallow cross section influences both mechanical support needs and the visual impact of the carving on the face plane.

The cutting style is carving, executed to emphasize the round geometry and to incorporate a negative relief motif on the face, a technique that exploits the material modulus to create clean edges and controlled depth while maintaining structural integrity. Traditional and contemporary lapidary methods were integrated in the fabrication process, starting with precise trimming and profiling on diamond impregnated wheels to establish the round outline and uniform thickness. Subsequent form shaping employed finer diamond grits with progressive abrading, allowing the carver to produce the crisp strokes and closed curves evident in the surface motif without inducing cleavage or thermal damage. The final surface quality was achieved with high quality polishing protocols, using successively finer abrasives and a final polish that produces an excellent polish, a mirror like finish on convex and flat planes that enhances apparent color and masks microtopography. Notably, this specimen is untreated, no enhancement, which means no dyeing, no bleaching, no polymer impregnation was applied, a factor of critical importance for connoisseurs and calibrated grading, and a determinant of long term stability under normal wear conditions.

From a practical and curatorial standpoint, the piece presents several advantages and considerations for integration into high end jewelry or collectible cabinets. The round shape and thin profile are ideally suited to flush inlay applications or a low profile bezel mount that protects the rim while allowing the carved face to read easily to the viewer. Given the medium color intensity and homogeneous appearance, the stone can be paired with both yellow and white metals, and can act as a color anchor in a composition that balances metal tone with complimentary accent stones. For collectors who prioritize natural provenance and lapidary integrity, this Burmese origin jade offers geological veracity and artisanal execution, and The Natural Gemstone Company vouches for the stated metrics, including the 24.69 carat weight, the 24.96 x 24.82 x 3.60 mm dimensions, the carving cut, the medium intensity green, the opaque translucency, the excellent polish, and the absence of any enhancement. Care recommendations include avoiding aggressive chemical exposure and extreme thermal shock, and selecting a mounting that supports the thin cross section to minimize impact risk.
