Presenting a beautiful transparent 1.50 carat cushion shape purple spinel from Burma Myanmar, this gem measures 6.81 by 6.31 by 4.34 millimeters, and has been cut with a mixed brilliant facet arrangement to balance color depth with optimal light performance. The medium color intensity yields a cultivated, versatile purple that reads neither muddy nor weak, and the cushion shape offers a classic, softened silhouette that flatters both contemporary and vintage settings. Clarity is graded very slightly included at eye level, which in practical terms means that the stone carries only minute internal characteristics that are not distracting to normal observation, and that contribute more to the gem story than to any visual impairment. The polish is excellent, which preserves crisp facet junctions and contributes directly to surface luster and immediate face up appeal. This spinel is natural and without enhancement, a point of distinction for collectors and connoisseurs who prioritize unheated, untreated origins. Sourced from Burma Myanmar, the gem benefits from a provenance that is well regarded in the trade for producing stable, attractive hues, and the combination of natural origin, precise cutting, and unenhanced clarity is a hallmark of quality that The Natural Gemstone Company is proud to offer.
Understanding why this spinel displays an exceptional sparkle begins with the mineral physics that define spinel as a species. Spinel crystallizes in the cubic system, which makes it optically isotropic, and this uniform optical behavior eliminates internal doubling of light that can sometimes soften facet contrast in anisotropic stones. Spinel also exhibits a relatively high refractive index for a transparent gem species, which increases the critical angle for total internal reflection and enhances the amount of light returned to the eye as brilliance. Coupled with a modest but measurable dispersion, the result is clean, lively flashes of white light and subtle spectral play, particularly when the cutting respects symmetry and facet proportions. The mixed brilliant cut used on this cushion brings together a step influenced pavilion geometry with a brilliant influenced crown, and that hybrid strategy concentrates light return through a well proportioned table, and generates strong scintillation as the gem moves. The excellent polish further amplifies these optical virtues by permitting light to enter and exit the stone with minimal scattering at the surface. In practice, the structural attributes of spinel, the careful geometry of the mixed brilliant cut, and the high polish yield a sparkle that reads as both bright and refined, a character that is often described as more lively than many lower index gem materials, and more restrained than highly dispersive stones, which makes this spinel particularly desirable for an educated buyer seeking balance.
For the knowledgeable purchaser, the combination of measurable attributes makes this 1.50 carat Burmese purple spinel a compelling acquisition. The medium intensity purple offers strong visual presence without overpowering settings or skin tones, the very slightly included clarity grade ensures eye clean appeal while preserving natural provenance, and the lack of enhancement supports both aesthetic integrity and long term value retention. From a durability standpoint, spinel rates around eight on the Mohs scale, rendering it suitable for daily wear in rings and bracelets when set with thoughtful protective bezel or prong designs. In terms of market context, natural untreated spinels from Burma command a premium relative to the general run of spinel material, and when a stone is well cut and well finished the incremental value is chiefly attributable to optical performance and certified origin. For care, routine cleaning with mild detergent and warm water and the occasional professional inspection of the setting will preserve brilliance and polish. As you consider this gem, The Natural Gemstone Company can provide additional measurements, photographic detail, and independent verification options to support confident buying decisions, and we welcome inquiries for bespoke mounting recommendations to best showcase the cushion form and lively mixed brilliant scintillation.
