0.90 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 0.90 carat oval blue sapphire measures 6.88 by 5.15 by 3.18 millimeters, and it has been expertly fashioned with a mixed brilliant cut, combining a brilliant style crown with a faceted pavilion that enhances scintillation while preserving a pleasing face up spread. The gem exhibits a clarity grade described as very slightly included when evaluated at eye level, and an excellent polish that allows light to travel unimpeded through the stone, revealing a light color intensity with subtle blue and violet tones characteristic of Ceylon material. The proportions yield an approximate depth of 53 percent, producing a shallow to medium profile that maximizes apparent size on the finger without compromising return of light, and the symmetry and facet junctions indicate careful lapidary control to preserve weight while optimizing optical performance. This sapphire has been heat treated, a conventional and stable enhancement used to refine color and clarity, and its documented origin of Ceylon Sri Lanka contributes to the expected pleochroic behavior and the delicate, luminous hue.

Compared to the broader market of sapphire options this stone is rare in both its size and its color profile, because near one carat Ceylon sapphires that combine high transparency, very slight inclusion visibility at eye level, and a light yet evenly distributed blue hue are uncommon, many similar stones are either smaller, more heavily included, or possess deeper, saturated tones that change design possibilities. The mixed brilliant faceting and the modest depth make this gem especially desirable for solitaire rings or minimalist three stone settings where a refined, airy blue is preferred over a saturated dark tone, and the excellent polish ensures lively scintillation in motion. For collectors and connoisseurs seeking a Ceylon sapphire that reads larger than its carat weight while maintaining clean eye appeal and precise cutting, this item represents a distinctive choice from The Natural Sapphire Company, and we can provide additional detailed images, facet diagrams, and mounting recommendations to assist with selection and design.
