For the educated buyer, spinel from Ceylon is prized for its combination of rich color and good crystal quality, and this specimen benefits from the durable nature of spinel with a hardness that makes it suitable for everyday wear in rings and other jewelry. The 0.90 carat weight sits in an attractive size range for a classic solitaire or a refined halo setting, and the near square cushion proportions contribute to visual stability and symmetry when set. Clarity graded as included at eye level means that natural inclusions are visible without magnification, these features authenticate the stone and are often appreciated by connoisseurs who value natural origin and unenhanced material.

The mixed brilliant cut and cushion outline work together to enhance the gemstone inherent properties of light reflection, by combining a faceting scheme that balances scintillation and color saturation. The brilliant style crown facets catch and break light into lively flashes, while the pavilion facet arrangement is optimized to return light through the table and crown, preserving the deep blue tone while creating attractive sparkle. The cutter has oriented facets to maximize color retention in the pavilion depth of 4.13 mm, avoiding excessive windowing and keeping the blue intensity strong even under varied lighting. Inclusions contribute to unique light patterns rather than obscuring the gem, and the excellent polish ensures minimal light leakage at facet junctions, improving overall brilliance. At The Natural Gemstone Company we emphasize how the combination of origin, cut, polish, and natural clarity define long term value, and this Ceylon blue spinel exemplifies a well balanced stone that will perform beautifully mounted in a range of settings, and that will appeal to collectors and thoughtful buyers seeking natural, responsibly sourced gemstones.
