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

This transparent 1.97 carat cushion shaped purplish blue spinel measures 7.51 x 6.07 x 4.69 mm, and features a mixed brilliant cut, very slightly included clarity evaluated at eye level, intense color intensity, and an excellent polish. The gem is natural, with no enhancement, and its origin is Ceylon, Sri Lanka. The mixed brilliant cutting style combines a brilliant crown with faceted pavilion structures that balance face up brilliance with depth of color, and the excellent polish produces clean, crisp facet junctions and precise light return across the table and pavilion facets.

Optically, this spinel exhibits the consistent color behavior expected of an isotropic gem, so there is no strong pleochroism and the purplish blue tone remains uniform as the stone is rotated. In cool daylight the saturated blue component of the tone becomes most apparent, delivering a clear, vivid blue with cool violet undertones. Under warm incandescent lighting the gem leans slightly toward its purplish character, presenting a softer, warmer violet blue. Under modern LED lighting the appearance will depend on the LED color temperature, with higher correlated color temperature LEDs emphasizing the blue facets and lower temperature LEDs enhancing the warmer violet facets. In direct sunlight the mixed brilliant cut produces lively scintillation and strong contrast flashes, and in subdued or diffused indoor light the stone retains depth and a steady, even face up color, while individual facet flashes become more subtle and broad. Point light sources produce crisp pinfire sparkle, and broader light fields yield broad flash highlights that emphasize the cushion form.

Practical considerations include the stone being suitable for a variety of settings, including rings, pendants, and bespoke jewelry, where its 1.97 carat weight and cushion proportions offer a balanced presence. Spinel is durable for daily wear when set appropriately, and routine cleaning with warm soapy water and a soft brush is sufficient to maintain its appearance. The Natural Gemstone Company presents this spinel as an untreated example of Ceylon origin material, offering transparency in provenance and gemological characteristics for buyers seeking natural, well finished spinel material.
