1.03 Ct. Spinel from Burma (Myanmar)

One beautiful transparent 1.03 carat cushion shape red spinel is offered by The Natural Gemstone Company, dimensions 7.22 by 4.66 by 3.06 millimeters, mixed brilliant cut, clarity grade very slightly included evaluated at eye level, intense color intensity, excellent polish, origin Burma Myanmar, no enhancement. The stone presents a strong, evenly saturated red with subtle purplish undertones when viewed face up, a color characteristic prized in Burmese spinels. The mixed brilliant design preserves a broad, luminous table while deploying pavilion facets that are calibrated to return maximum light, producing an overall balance of brightness and depth. Eye level clarity of very slightly included indicates only minor internal features visible under careful inspection, without compromising the stone on standard loupe or naked eye viewing for typical jewelry applications.

Technically the cushion outline with mixed brilliant faceting combines a modified brilliant crown with a series of elongated pavilion facets, a construction that enhances scintillation along the length of the stone while maintaining intense body color. The measured depth proportion is approximately 51.5 percent, a proportion that supports a strong light return with minimal windowing or dark centers. The cutter has preserved symmetry and facet alignment to high tolerances, and the polish is executed to a very fine level, minimizing surface haze and allowing crisp facet junctions to act as efficient mirrors. These precise facets produce a controlled pattern of flashes under directional light, where the brilliant crown facets fragment incoming light into lively scintillation and the pavilion facets provide layered contrast that emphasizes the red saturation.

Optically spinel is isotropic with a refractive index range near 1.718 to 1.736 and a dispersion value around 0.018, characteristics that define its reflective behavior in relation to other red gemstones in its category. Compared with corundum based rubies, which have a higher refractive index near 1.762 to 1.770 and marginally higher dispersion, spinel will generally present slightly softer brilliance but a more uniform face up color because it lacks pleochroism. The absence of dichroism or strong pleochroism in spinel yields cleaner, more consistent color distribution, while corundum can show color zoning or differential color when rotated. Compared with garnets of similar hue, which may have higher or more variable refractive indices depending on species, this spinel offers a cleaner internal appearance and a more stable, saturated red without the tendency for the brownish overtones that affect many red garnets. Compared with red tourmaline, which commonly exhibits notable pleochroism and a different light scattering behavior, the spinel will appear more homogenous and steadier in tone from different viewing angles. The relatively modest dispersion of spinel limits flashy spectral fire, but its strong color saturation and high transparency compensate by producing deep, vivid internal reflections that convey depth rather than prismatic sparkle.

From a practical and aesthetic standpoint the gem is exceptionally well suited for jewelry that benefits from both color intensity and optical stability, such as a classic ring center or an elegant pendant where the cushion outline reads generously. The mixed brilliant philosophy of the cut allows the gem to perform well under both direct and diffuse lighting, providing controlled scintillation without sacrificing the intense red that defines its appeal. The no enhancement origin and Burmese provenance add value for connoisseurs who prioritize natural state stones with reputable source history. For buyers seeking a technical comparison, this spinel offers a rare combination of vivid color, disciplined faceting, and clean clarity that sets it apart from many other red gemstones, and The Natural Gemstone Company stands behind its craftsmanship and presentation for discerning collectors and jewelers.
