1.06 Ct. Purplish Blue Spinel from Ceylon (Sri Lanka)

This transparent purplish blue spinel, weighing 1.06 carats and measuring 7.02 x 5.10 x 3.58 mm, is a fine example of Ceylon spinel offered by The Natural Gemstone Company. The cushion shape and mixed brilliant cut have been executed to exacting standards, producing crisp facet junctions and an excellent polish that maximizes light return. At a light color intensity this gem displays a delicate yet distinct purplish blue hue that is evenly distributed across the table, and with an eye clean clarity grade evaluated at eye level the stone presents no visible inclusions to interfere with optical performance. There has been no enhancement, which is an important consideration for educated buyers who value untreated, natural material. Origin from Sri Lanka is associated with a long history of well formed crystal material and consistent cutting traditions, and the combination of provenance, transparency, and natural color makes this spinel notably desirable for both collectors and bespoke jewelry commissions.

The spinel structure itself contributes directly to the gem s exceptional sparkle, and understanding the science helps explain why this stone stands out. Spinel is an isotropic mineral with a relatively high refractive index for a non birefringent gem, which means light entering the stone is strongly refracted and then returned to the eye when the pavilion and crown are cut with precision. The mixed brilliant cutting style combines the depth and window control of step facets with the scintillation and flash of brilliant facets, creating a lively play of light and dark areas that read as intense sparkle in motion. The excellent polish minimizes surface scattering and allows the internal facet pattern to perform at peak efficiency, while the eye clean clarity ensures that light pathways remain uninterrupted by inclusions. In practical terms this means bright white flashes, lively scintillation, and a pleasing depth to the blue purple tone, all housed in a durable material that rates well for daily wear. For the informed buyer seeking a natural, untreated, and well cut treasure, this Ceylon cushion spinel from The Natural Gemstone Company represents a compelling combination of aesthetics, physical properties, and provenance.
