10.87 Ct. Spinel from Ceylon (Sri Lanka)

This exquisite purple spinel from Ceylon carries with it the quiet dignity of gems that have been treasured for generations, a stone that feels as at home in a royal treasury as it does in a modern collector’s cabinet. Spinel has long been a symbol of enduring beauty, historically prized across Asia and Europe for its vivid tones and remarkable stability, and this 10.87 carat oval is a perfect illustration of that legacy. Measuring 15.01 by 11.73 by 8.80 millimeters, its oval proportions are classical and flattering, evoking the graceful silhouettes favored in heirloom settings. The intense color intensity and transparent clarity of this gem allow its hue to read as both regal and serene, a purple that moves between lilac and amethyst under changing light. Untreated and unenhanced, this spinel speaks to the purity of nature and the careful selection standards of The Natural Gemstone Company, each facet and plane reflecting a lineage of craftsmanship and the long geological story of Ceylon’s storied deposits.

The sparkle of this gem is born in both its innate crystal structure and the precision of its cutting. Spinel crystallizes in an isometric system, which means it has a single refractive index and no birefringence, producing sharp, undoubled facet reflections that read as crisp brilliance to the eye. The mixed brilliant cut employed here combines the scintillation and light return of a brilliant crown with a step or modified pavilion, concentrating flashes of light across the large 15 by 11 millimeter table and along the elegant oval outline. Eye clean clarity at standard viewing distances ensures uninterrupted light pathways, while the excellent polish maximizes mirrorlike facet planes that throw lively white sparkle and scintillation rather than diffuse haze. With a Mohs hardness that readily endures daily wear and a weight of 10.87 carats that delivers presence and substance, this purple spinel is a rare fusion of historical poise and optical performance. For collectors and connoisseurs seeking a gem that reads as timeless, luminous, and authentically natural, The Natural Gemstone Company offers this superb Ceylon spinel as a statement of both heritage and radiance.
