20.70 Ct. Cabochon Jade from Burma (Myanmar)

One specimen presented by The Natural Gemstone Company is an opaque green jade weighing 20.70 carats, cut en cabochon into a classic oval form. The stone measures 18.01 millimeters by 12.97 millimeters by 10.29 millimeters, providing substantial presence for a variety of jewelry applications. The cut is a rounded domed cabochon that emphasizes surface luster and color uniformity, and the finish is described as an excellent polish delivering a smooth, reflective surface. This piece is natural with no enhancement reported, and its documented origin is Burma, Myanmar, a source historically associated with fine green jade material.

Color and clarity are central to evaluating this jade. The color intensity is classified as medium intense, yielding a vivid green that is neither overly dark nor pastel, and presenting an even saturation across the visible surface. The stone is opaque, which moderates light transmission and focuses attention on surface tone and texture rather than internal translucency. Clarity is graded as very slightly included when examined at eye level, indicating the presence of a small number of minor inclusions that are visible without magnification but do not materially detract from the overall appearance. These inclusions are consistent with natural origin and can appear as dark pinpoints or small mineral spots that contribute to the gemological character of the piece. The cabochon profile and the high degree of polish reduce the visual impact of these internal features while enhancing the uniformity of the green field.

From a practical and design perspective, the dimensions and weight of this specimen support a range of mounting choices. The substantial 20.70 carat weight and the domed cabochon format are well suited to settings that present the surface prominently, including bezel mounted rings, pendants with protective frames, brooches, and high quality bespoke pieces where the stone is intended to be the focal element. The oval outline and balanced proportions will simplify design and setting, while the excellent polish contributes a tactilely pleasing finish and a reflective sheen that benefits from secure, slightly raised bezels or low profile prongs in custom work. Handling and care recommendations for natural jade include avoiding prolonged exposure to harsh chemicals, strong acids, and extreme temperature changes, and avoiding ultrasonic cleaners when inclusions or fracture features are present. Routine cleaning with warm water, mild detergent, and a soft brush or cloth will maintain surface luster without risk. The documented absence of enhancement, combined with Burmese origin, provides clear descriptive attributes for appraisal and insurance purposes.

This jade is offered with factual gemological descriptors to assist in design, appraisal, and acquisition decisions, and The Natural Gemstone Company is available to provide further imagery and measurement verification upon request. The combination of a substantial 20.70 carat weight, medium intense green color, very slightly included clarity at eye level, and an excellent polish makes this cabochon a strong candidate for a signature piece where natural character and a smooth, reflective surface are desired. Prospective clients seeking additional technical information, provenance documentation, or guidance on appropriate setting options are invited to contact The Natural Gemstone Company for expert assistance and to arrange viewing or secure handling of this Burmese jade specimen.
