1.25 Ct. Grey Spinel from Burma (Myanmar)

This transparent 1.25 carat cushion grey spinel presents precise proportions and a restrained tonal palette that will appeal to experienced connoisseurs, the gem measures 6.36 x 5.55 x 4.80 mm, it is fashioned in a mixed brilliant cut that combines a modified brilliant crown with a faceted pavilion geometry optimized for light return, clarity has been graded as slightly included when viewed at eye level, color intensity is described as intense despite the cool grey hue, polish is excellent, and there has been no enhancement applied, origin is Burma. The cushion outline is softly rounded yet geometrically well defined, the mixed brilliant strategy preserves both scintillation and depth of tone by balancing numerous small crown facets with larger pavilion facets, the result is a visual complexity that rewards movement and varied lighting conditions. The Natural Gemstone Company is offering this spinel as a specimen for jewelry that values technical cutting and natural material integrity, every aspect of its presentation supports use in settings that emphasize the stone rather than obscure it.

Careful attention to faceting is evident when the stone is examined under magnification, the mixed brilliant arrangement produces crisp facet junctions and a controlled table size that stabilizes the gem s face up appearance, the table facet is proportioned to allow internal flash while permitting the depth to contribute to color saturation, the measured depth of 4.80 mm relative to the average of length and width which is 5.955 mm yields a depth ratio of approximately 0.81, this relatively deep profile concentrates light into the pavilion producing intense internal reflections and a compact field of scintillation. The cushion shape in this instance benefits from a slightly deeper pavilion because it enhances the stone s grey tone, the polished facet planes show no evidence of abrasion or laps in finish, excellent polish ensures that facet edges remain crisp while minimizing surface diffusion of light, a well executed girdle allows secure bezel or prong seating without compromising symmetry.

Optical and material properties reinforce the gem s suitability for long term wear, spinel typically exhibits a refractive index in the range 1.712 to 1.718 and a low dispersion, these parameters translate to elegant, white brilliance rather than overt fire, the result complements the grey hue by emphasizing tonal depth and subtle flashes of light, natural spinel is not pleochroic in the way some colored stones are, this provides color consistency across different orientations. The clarity classification slightly included reflects the presence of small, characteristic internal features that do not affect structural integrity, such inclusions are typical of natural Burmese spinel and often serve as identification markers for origin. Hardness on the Mohs scale is 8 which imparts strong resistance to scratching and supports everyday wear in rings, pendants, and other jewelry types, specific gravity near 3.6 contributes to a satisfying hand feel relative to stones of comparable size.

Because this spinel is unenhanced and originates from Burma, its natural beauty will continue to captivate for generations, the lack of treatments means color and clarity will remain as cut from the rough, without the need for retreatment or concern over altered stability. The deep mixed brilliant cutting strategy ensures that even as fashion evolves, the gem s luminous behavior will remain relevant, its restrained grey tone is versatile in design contexts and will patina visually rather than degrade, periodic professional cleaning and routine inspection of the mounting will preserve the polish and protect the integrity of the stone. Collectors and jewelers seeking a technically strong, visually compelling grey spinel will find this example from The Natural Gemstone Company to be an enduring choice, it pairs technical excellence in cutting with natural provenance and material stability, a gem designed to deliver consistent performance and quiet, persistent allure over many years.
