0.71 Ct. Pinkish Purple Spinel from Ceylon (Sri Lanka)

This transparent 0.71 carat oval spinel measures 6.04 x 5.02 x 3.15 mm, presenting a face up profile that maximizes spread for its weight, the mean diameter being 5.53 mm and the total depth approximately 57 percent, a proportion that balances light return and visible size. The cutting style is faceted with a mixed brilliant cut configuration, where a brilliant facet arrangement on the crown is married to a controlled pavilion geometry, producing a lively pattern of contrast and scintillation. The polish is excellent, and the symmetry is precise, yielding crisp facet junctions and minimal windowing under direct lighting, attributes that demonstrate a high level of lapidary craftsmanship. Clarity is graded as very very slightly included when evaluated at eye level, providing an essentially eye clean appearance with minute internal features that do not interrupt the visual performance or durability of the stone. This spinel is natural with no enhancement, and it originates from Ceylon Sri Lanka, a source noted for producing material with attractive color and reliable crystalline quality, the combination of provenance and untouched character adding measurable collector value. The Natural Gemstone Company presents this gem as an exemplar of careful cutting and natural material integrity.

From an optical and gemological standpoint this pinkish purple spinel behaves differently from more familiar gemstones, and that difference is what gives it distinction, spinel is singly refractive and has a refractive index range near 1.712 to 1.736, a dispersion on the order of 0.018, and a vitreous to adamantine luster that reads as a bright, glasslike brilliance, by comparison diamond exhibits much higher refractive index and dispersion and therefore greater fire, while corundum species such as sapphire and ruby sit at a slightly higher refractive index and display pleochroism that can cause color shifts on different facets. The consequence is that a well cut spinel such as this yields an even, saturated face up color with uniform light return and lively scintillation rather than overt flash, the mixed brilliant faceting amplifies contrast and produces a controlled play of light that emphasizes color saturation rather than scattering it, the result is a gemstone that reads as richly colored and lively in motion, especially under natural daylight, where the medium color intensity of this specimen resolves into a nuanced pink violet that remains consistent as the gem is tilted, an optical stability prized by designers and collectors alike.

Craftsmanship notes for setters and appraisers include the stone dimensions and proportion profile, the 57 percent depth is well suited to classic prong or bezel settings that seek to show the maximum table while protecting the girdle, the oval outline at 6.04 x 5.02 mm is flexible for single stone rings, pendants, or as accent stones in multi gem layouts, and the excellent polish reduces extraneous surface diffusion that can dull perceived brilliance once mounted. Hardness near 8 on the Mohs scale renders spinel suitable for daily wear in rings provided standard protective settings are used, and the unenhanced nature of the material assures predictable colorfastness and thermal stability during jewelry fabrication. Compared to commonly encountered purple gems such as amethyst or rhodolite garnet, this Ceylon spinel offers a combination of higher toughness and a clarity profile that more closely approaches gem quality corundum, while exhibiting a distinct vibrancy that is not dependent on treatment, for collectors seeking naturally pristine material the absence of enhancement is a significant provenance indicator.

In summary this 0.71 carat oval pinkish purple spinel is distinguished by precise mixed brilliant cutting, an eye clean visual field, excellent polish, a balanced 57 percent depth, and natural Ceylon origin with no enhancement, these technical attributes combine to produce a gem whose brilliance is characterized by consistent light return, vibrant color saturation, and lively scintillation, qualities that set it apart from more common colored stones and that make it particularly attractive to discerning buyers who value technical excellence and natural integrity. The Natural Gemstone Company is pleased to offer this gem as part of our curated inventory of untreated gemstones, and we welcome inquiries regarding mounting options, grading documentation, and bespoke presentation for collectors and jewelers.
