21.20 Ct. Cabochon Jade from Burma (Myanmar)

This specimen is an opaque green jade of substantial presence, weighing 21.20 carats, presented in an oval outline with precise dimensions of 18.18 x 13.19 x 10.29 mm. The piece has been fashioned as a classical cabochon, featuring a high, symmetrical dome and a well centered axis, which serves to maximize the perceptible color depth and surface luster. Clarity has been graded as very slightly included when evaluated at eye level, with discrete dark granular inclusions distributed intermittently across the body, contributing to character without detracting from overall visual coherence. Color intensity is assessed as medium intense, exhibiting a steady apple to mid grass green that is evenly distributed across the table, and polish quality is excellent, yielding a bright, near wet sheen across the dome. No enhancement has been applied to this material, and provenance is recorded as Burma Myanmar, which is consistent with the mineralogical character of traditional Burmese jadeite material offered by The Natural Gemstone Company.

From a lapidary and gemological perspective the cabochon demonstrates careful attention to proportion and surface finish, which are critical for opaque stones where faceting is not employed to generate scintillation. The oval proportions are balanced to present a pleasing length to width ratio on finger or pendant, while the 10.29 mm height establishes a substantial crown profile that emphasizes the stone body color and the internal texture. The cutting technique preserves a smooth transition from crown to girdle, with the girdle rounded rather than crisp, minimizing stress concentration and reducing the risk of chipping in service. The excellent polish was achieved through progressive abrasion to final lapping, resulting in a low microtopography on the surface that permits specular highlights to read as single, coherent reflections rather than fractured sparkles. The very slightly included clarity grade indicates the presence of small inclusions that are visible with the unaided eye under direct lighting, but these inclusions act more as identifying characteristics than as detractors, and they reinforce the natural origin and untreated status of the stone.

For custom jewelry design the dimensions and mass of this cabochon make it ideal as a primary center in a statement ring or as the focal element in a pendant, where the dome height can be accommodated without compromising wearability. Given the opacity and waxy luster, a bezel setting with a low to moderate flange will offer the most secure and aesthetically coherent mounting, producing a continuous visual frame that complements the smooth dome. If the client prefers visual refinement and contrast, a partial bezel combined with discreet prongs at the shoulders can suspend the cabochon and allow side light to articulate the dome curvature. Metal selection has a pronounced effect on perceived color, therefore platinum or 18 karat white gold will lend a crisp, modern contrast and will cause the green to read slightly cooler, while 18 karat yellow gold will warm the green and create a vintage or heirloom sensibility. For a luxury architectural treatment consider a raised collet with a scalloped gallery and pavé shoulders, which will balance the stone mass while preserving wrist clearance.

When planning complementary gemstones it is advantageous to think in terms of contrast and harmony, to either accentuate the jade green or to create a nuanced color dialogue. Small round brilliant diamonds set as a halo and shoulder accents will introduce high dispersion scintillation, creating a lively frame against the jadeite waxy surface, and step cut baguette diamonds will impart a structured, Art Deco aesthetic that emphasizes geometry over flash. For color contrast, deep blue sapphires will produce a dramatic triad that makes the green appear fresher and more vivid, and violet to purple sapphires will generate a rich color juxtaposition that reads as regal. For a monochromatic tonal scheme, lighter green stones such as peridot or chrysoprase can be used as accent stones to form graduated color fields. If the design seeks softness, pastel morganite or pale pink sapphires in a scattered cluster can warm the overall palette and offer a feminine counterpoint. Because the cabochon is relatively tall, consider low profile side stones or a graduated halo to keep the overall center of gravity manageable, and specify secure bezel or collet techniques to protect the girdle and base during daily wear. This untreated Burma Myanmar jade cabochon is offered by The Natural Gemstone Company, and it presents a rare combination of weight, color intensity, and fine polish that will serve as a distinguished focal point in a well executed custom piece.
