1.86 Ct. Red Spinel from Burma (Myanmar)

This exceptional transparent 1.86 carat round red spinel measures 7.68 x 7.66 x 4.97 mm, it is faceted with a mixed brilliant cut, and it displays an intense color intensity with an excellent polish. The dimensions and cutting style were chosen to maximize both color saturation and light return, the slight variation between the two diameter measurements reflects careful cutting to preserve weight and optical performance, and the 4.97 mm depth produces a harmonious balance between brilliance and fire. The mixed brilliant cut combines the scintillation of a brilliant crown with a pavilion facet arrangement that opens the color, this approach is particularly effective for red spinel because it allows the stone to hold deep, even saturation while still returning lively sparkle. At 1.86 carats this spinel sits in a size class that is meaningful to collectors and jewelers, large enough to make a bold statement in fine jewelry, while still exhibiting the kind of refinement that connoisseurs look for in a classic gemstone.

Clarity is graded as slightly included, evaluated at eye level, which means the stone is transparent and clean to most observers, with minor internal characteristics that do not materially detract from the gem s overall beauty. Slightly included in practical terms indicates that inclusions are small and localized, they may become more apparent under magnification or to a trained eye, but they do not interfere with the passage of light or the intense hue that makes this spinel so desirable. The polish is excellent, ensuring that the pavilion and crown facets meet crisply and that surface luster is maximized, this precision of finishing enhances brilliance and allows the red color to read clearly through the table. The stone has been heat treated, a common and widely accepted enhancement for spinel, employed to stabilize or intensify existing color and to relieve any silk like inclusions, the treatment is stable under normal wear, fully disclosed, and does not diminish the gem s intrinsic value when documented and understood by an educated buyer.

This spinel originates from Burma, also known as Myanmar, a region with a storied history for producing some of the world s finest red spinels. The material we see today began forming millions of years ago deep within metamorphic marble beds, where high temperatures and pressures induced mineral reactions between aluminum rich and magnesium rich protoliths. Spinel is a magnesium aluminum oxide mineral with an isometric crystal structure that favors octahedral growth, trace chromium incorporated into the crystal lattice imparts the vivid red color, while minor amounts of iron and other transition elements can modify tone and saturation. In Myanmar s classic deposits, repeated episodes of burial, metamorphism, and uplift allowed spinel crystals to grow in pockets and veins, and subsequent erosion liberated those crystals into alluvial gravels that miners worked by hand and by river. Over geological time scales, this is a process of transformation, the stone s chemistry and crystal habit record a history of heat, pressure, and fluid interaction, and what reaches the lapidary is a snapshot of those forces rendered in color and light.

At The Natural Gemstone Company we recognize that an educated buyer values provenance, technical detail, and responsible disclosure, so we present this 1.86 carat Burmese red spinel with full information about its dimensions, cut, clarity, polish, and enhancement. Spinel s practical durability, with a hardness of about 8 on the Mohs scale and a specific gravity around 3.6, makes it suitable for daily wear in rings and pendants, its refractive properties, with an index near 1.718, contribute to lively brilliance that separates a well cut spinel from lesser material. The combination of intense, natural red color, transparent clarity, and a skilled mixed brilliant cut yields a gemstone that appeals to collectors, gemologists, and jewelers seeking a stone with both visual impact and geological pedigree. We stand behind the ethical sourcing and full disclosure of our gems, and we are available to provide additional documentation, imaging, and detailed inspection notes to help you evaluate how this red spinel will perform in your next design or collection piece.
