1.13 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.13 carat cushion shape blue sapphire from Ceylon is an excellent example of natural, untreated material offered by The Natural Sapphire Company, with precise measurements of 6.44 x 5.07 x 3.61 mm. The mixed brilliant cut marries a brilliant pavilion with a faceted crown geometry that has been optimized to return light and create lively scintillation, resulting in maximum light play across the table and crown facets. With a depth of approximately 3.61 mm against an average of the length and width of approximately 5.755 mm the stone exhibits a depth around 62.8 percent, a proportion that contributes to a pleasing balance between face up presence and internal reflection. The polish has been graded excellent which enhances the crispness of facet junctions and ensures that light is transmitted and reflected with minimal surface diffusion. The medium intense color intensity is classic Ceylon blue, offering a saturated blue that reads vibrantly in daylight and under warm light, making the sapphire versatile for both single stone settings and more intricate jewelry designs.

From a connoisseur perspective the clarity grade of slightly included evaluated at eye level indicates small natural inclusions that are consistent with an untreated origin, inclusions that do not materially disrupt the overall transparency or the optical performance but do provide confirmation of natural provenance. The absence of any enhancement is a significant value attribute given that a majority of sapphires in the market have been heat treated to modify color or clarity, and an untreated Ceylon sapphire with medium intense blue color commands premium interest from informed buyers. The mixed brilliant faceting geometry produces a combination of broad color flashes and lively pinpoint scintillation, so that the stone exhibits both color saturation and dynamic sparkle without appearing dark or windowed. For buyers seeking a well proportioned, natural Ceylon sapphire with strong visual appeal and durable value characteristics The Natural Sapphire Company presents this gem as an exceptional candidate for a timeless ring or bespoke piece, where the faceting architecture will deliver maximum light play and enduring beauty.
