0.76 Ct. Purple Spinel from Ceylon (Sri Lanka)

This 0.76 carat transparent purple spinel from Ceylon, Sri Lanka, offered by The Natural Gemstone Company, presents a compelling combination of natural origin, excellent polish, and classic proportions that appeal to the informed buyer. The oval measures 6.25 x 5.04 x 3.31 mm, giving a depth that balances face up presence with light return, and its medium color intensity provides a true, even purple that is characteristic of Sri Lankan spinel. The gem is untreated, no enhancement, and carries a clarity grade of slightly included as evaluated at eye level, meaning small internal features are present but do not distract from overall beauty or compromise structural integrity. Spinel is an isotropic species with a refractive index in the range of approximately 1.712 to 1.718 and a Mohs hardness of about 8, which translates into durable wear for everyday jewelry, and an attractive adamantine luster that works well in both modern and classic settings.

The cutting style is faceted with a mixed brilliant cut, and the cutting geometry is the key to how this gem interacts with light. A mixed brilliant cut typically combines brilliant crown facets with a modified pavilion geometry, which creates a dynamic interplay between brilliance and color saturation. In this oval, the crown facets disperse incoming light and break it into flashes of white light, while the well proportioned pavilion facets return that light through the table, maximizing perceived brightness. The measured depth and well executed facet junctions, together with an excellent polish, minimize light leakage and enhance scintillation as the stone moves. Because spinel is isotropic and free of pleochroism, the mixed brilliant design emphasizes uniform color distribution while producing lively flashes and a pleasing balance between fire and brilliance. For collectors and jewelry designers, this means the stone will read consistently on the finger or in a pendant, and the slight inclusions noted at eye level are typical of natural material and often become less visible once the stone is set. The overall package, from untreated origin to precision cutting, makes this purple Ceylon spinel a smart acquisition for an educated buyer seeking a durable, naturally beautiful gemstone, offered with the assurance and expertise of The Natural Gemstone Company.
