0.57 Ct. Greyish Violet Spinel from Ceylon (Sri Lanka)

This 0.57 carat oval greyish violet spinel measures 5.47 x 4.17 x 3.22 mm, the proportions present an immediate sense of balance for an oval of this size, the cutting style is fully faceted, executed as a mixed brilliant cut that combines a brilliant style crown with a modified pavilion to optimize both flash and overall light return, the crown presents well formed kite and star facets meeting a clean table facet, the pavilion uses a constellation of radial mains that channel light back through the crown, the clarity grade is very very slightly included as evaluated at eye level, the stone is effectively eye clean with only minute internal features visible under careful scrutiny, the color is intense greyish violet with even saturation across the table and no distracting zoning, the polish is excellent with crisp facet junctions and mirror like facet planes, the gem shows no enhancements, and the provenance is Ceylon Sri Lanka, a source historically associated with top quality spinel material, The Natural Gemstone Company offers this piece as an unaltered specimen that displays the original optical character of Sri Lankan spinel.

Optically this spinel performs with a lively brilliance and precise facet contrasts, spinel is an isotropic mineral, which means it lacks double refraction and pleochroism, this isotropic behavior produces exceptionally crisp internal reflections and uniform color under changing light, whereas corundum species such as sapphire can display pleochroism and birefringent doubling of facet images, these effects can soften the apparent brilliancy, in practice a well cut spinel like this one will often appear brighter across the full face of the gem when compared to many colored stones of similar size, the mixed brilliant approach maximizes scintillation, the carefully judged crown height and pavilion depth in this oval channel light back as strong, coherent flashes rather than dispersed or muddled reflections, compared to sapphire and ruby this spinel will show a more immediate, even white light return across facets, compared to garnet and topaz this spinel exhibits finer facet definition and a cleaner, more saturated hue, compared to diamond the spinel will not match diamond in absolute brilliance or dispersion, yet in day to day wear this spinel will read as a lively, intensely colored gem with a balanced interplay of brilliance and color that often makes it more visually commanding than many colored stones of comparable size.

From a craftsmanship and practical perspective this greyish violet spinel is particularly well suited to high quality jewelry, the oval outline at 5.47 x 4.17 mm and the 0.57 carat weight sit comfortably within classical proportions used for rings and pendants, the excellent polish minimizes surface light loss and the VVS clarity at eye level gives a clean presentation under loupe and to the naked eye, the absence of enhancement enhances long term collector appeal and simplifies mounting decisions related to heat or resin sensitivity, given the intense color and mixed brilliant cutting approach metal choices such as platinum or 18 karat white gold will emphasize the stone s cool violet tone, while 18 karat rose gold will add a subtle warmth that can make the grey component read softer against skin, practical recommendations for setting include a secure bezel for everyday wear or a low profile prong setting for maximum exposure to light, The Natural Gemstone Company will happily provide further photographs under daylight balanced illumination, a faceted diagram on request, and consultation on setting options to preserve and showcase the inherent optical strengths of this Sri Lankan spinel.
