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

This 0.87 carat oval greyish violet spinel presents dimensions of 7.20 x 5.82 x 2.95 mm, with a calculated depth proportion of approximately 45 percent, an ideal balance for light return in an oval outline. The cutting style is faceted, executed in a mixed brilliant cut that places a fine brilliant facet array on the crown and a calibrated pavilion facet pattern to optimize scintillation and window control. Clarity is graded very slightly included when evaluated at eye level, and the polish is excellent, with crisp facet junctions and no surface abrasion visible under loupe scrutiny. The color shows intense saturation with a greyish violet hue that remains stable through rotation due to spinel isotropy, and the specimen is unenhanced, with natural color and no heat or diffusion treatments recorded. Origin is Ceylon Sri Lanka, a classic source with a long history of producing gems of fine crystalline quality.

Technically, spinel is isotropic with a single refractive index near 1.718, which makes cut symmetry and facet geometry the primary drivers of brilliance rather than directional pleochroism. The mixed brilliant design on this stone exploits that optical behavior to deliver strong faceted return and lively scintillation, while the moderate depth prevents light leakage common in shallower cuts. The intense greyish violet color is unusual relative to the more common raspberry and red spinels, offering a subtler, more sophisticated presence in jewelry. Compared to historic spinels such as the famed Black Prince Ruby and the Timur Ruby, both of which are large red spinels that commanded royal settings, this Sri Lankan example is distinguished not by size but by tone and clarity, and by being unenhanced. Whereas those famous pieces are celebrated for saturated red, this stone occupies a rarer niche in the spectrum, recalling the subdued elegance of museum quality spinels while remaining distinctly modern in its grey violet expression.

For collectors and designers seeking a gem that marries classical spinel pedigree with technical refinement, this 0.87 carat oval offers high craftsmanship and reliable performance in wearable pieces. Its proportions and mixed brilliant faceting make it an excellent candidate for a close halo or solitaire setting where the intense color and excellent polish will be foregrounded. Provenance and condition are documented by The Natural Gemstone Company, ensuring that the combination of natural origin, no enhancement, and careful cutting is verifiable for both appraisal and bespoke design projects.
