3.05 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exceptional 3.05 carat round blue sapphire from Ceylon Sri Lanka embodies the classical balance of weight and proportions that experienced connoisseurs seek. Its measured dimensions are 8.19 by 8.11 by 5.75 millimeters, yielding an overall visual presence that reads larger than its weight might suggest thanks to a well considered spread. The gem displays a vivid color intensity, a deep saturated blue with slight electric tones toward the secondary spectrum under strong light, and the hue distribution is consistent across the entire table and pavilion planes. Evaluated at eye level the clarity is described as very very slightly included, which in practical viewing yields an eye clean presentation, and the transparent material allows full traversal of light without the cloudy diffusion that can diminish color saturation. Heat treatment has been applied in a controlled manner to stabilize and intensify the blue, an enhancement method that is well established for Ceylon sapphires and that preserves natural zoning characteristics while enhancing overall tone and saturation.

The cutting style is a mixed brilliant, executed to maximize both color and light return in a medium to deep depth profile. The mixed brilliant approach integrates a brilliant facet arrangement on the crown, with a more elongated and modified pavilion facet set that deepens the visual color pumping without sacrificing return. The crown faceting matrix creates multiple small triangular and kite facets that act as light catchers, providing strong scintillation and lively contrast when the stone is rotated. The pavilion facets have been proportioned and angled to promote internal reflection and to direct selective wavelengths back through the crown, increasing perceived color intensity and depth. Based on the supplied dimensions the stone exhibits a depth to average diameter ratio of approximately seventy point five percent, a departure from classical shallow brilliant ideals, which in this execution contributes to the sapphire feeling denser and more saturated in tone, particularly in controlled lighting environments.

Craftsmanship details are manifest in the excellent polish and the meticulous facet junctions, which are critical to producing a clean, sharp light pattern from every viewing angle. The lapidary work on this piece emphasizes crisp girdle symmetry, precise facet alignment, and a table proportion that optimizes both brilliance and color. The excellent polish yields mirror like facet surfaces that minimize light scattering, and the careful symmetry prevents dead zones or windows that would otherwise reveal interior features or reduce scintillation. Although the clarity grade at eye level is very very slightly included, the combination of expert cutting and superior polish makes those minor inclusions practically invisible during normal wear, resulting in an overall visual impression that approaches flawless performance. This perceived flawlessness is not asserted as a clarity grade, rather it is the product of an integrated approach to cutting, polishing, and heat treatment that together present the stone as composed and optically coherent from crown to culet.

For jewelers and discerning clients who value technical refinement, this sapphire from The Natural Sapphire Company is an ideal candidate for designs that highlight its depth and richness. Its robust durability and hardness characteristic of corundum make it suitable for ring settings that see daily wear, provided standard care is observed. The mixed brilliant cut responds beautifully to both open prong settings that showcase the pavilion color and closed bezel designs that emphasize the crown brilliance, and its size and spread work effectively as a solitaire or as the central stone in a halo composition where surrounding accents can enhance perceived carat weight and fire. The documented origin, heat treatment history, and the evident lapidary quality mean that the piece will integrate easily with bespoke fabrication plans, and The Natural Sapphire Company stands ready to provide further measurements, facet diagrams, or matching services for complementary stones. This sapphire rewards close inspection and repetitive viewing, consistently revealing layered optical behavior that reinforces its technical pedigree and aesthetic appeal.
