2.06 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This listing from The Natural Sapphire Company presents one transparent 2.06 carat round shape blue sapphire, with dimensions 6.88 by 6.89 by 5.16 mm, faceted with a mixed brilliant cut, and an excellent polish. The stone exhibits vivid color intensity, and a clarity grade of very slightly included evaluated at eye level, characteristics that allow the blue to read clean and saturated in both direct and diffused lighting. The gem has been heat treated to enhance tone and uniformity, a stable and commonly accepted enhancement for corundum, and the material originates from Ceylon, Sri Lanka, a source known for lively, well saturated blue sapphires. The mixed brilliant faceting strategy balances light return and color depth, centering the vivid blue in the crown while maintaining strong internal contrast and well defined facet reflections, suitable for a variety of jewelry settings.

When compared to other gemstones in its category, this Ceylon sapphire demonstrates notable reflective qualities that are characteristic of corundum, yet distinguished by origin and cut. Corundum typically has a refractive index in the range of 1.762 to 1.770, delivering a vitreous luster and clear facet definition, and this stone benefits from that optical foundation. Against visually similar materials, such as spinel, which has a lower refractive index and therefore a softer internal brilliance, this sapphire returns light with greater contrast and a more pronounced scintillation. Compared to tanzanite and other beryllium bearing blue gems, which may show strong pleochroism and a different directional flash, the sapphire offers a steadier, more uniform blue across viewing angles, enhanced by the mixed brilliant cut which maximizes return of white light while preserving color saturation. Relative to other notable sapphire origins, Ceylon material often appears brighter and more lively than deeper, velvety stones from certain other sources, offering more apparent brilliance under varied lighting conditions, while Kashmir and certain Burmese examples may present a velvety depth that trades some flash for richness. In summary, this 2.06 carat Ceylon sapphire combines exemplary polish and a thoughtful cut with corundum s inherent refractive properties to yield lively facet reflections and consistent, vivid blue, distinguishing it among peer gemstones in its category.
