2.14 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This exceptional transparent blue sapphire from Ceylon, Sri Lanka carries a precise set of proportions that define its optical performance, a 2.14 carat weight, cushion shape, and exact dimensions of 6.88 by 6.62 by 5.03 millimeters, the material is gem quality corundum with the characteristic trigonal crystal structure that yields a high refractive index around 1.76 to 1.77, this refractive index combined with a modest birefringence and low dispersion creates a balance of brilliance and color retention unique to fine sapphires, the stone has been heat treated to enhance its natural blue hue, the color grade is vivid in intensity, the clarity is evaluated as very very slightly included at eye level indicating inclusions are microscopic or located away from critical facet junctions, and the overall finish is described as excellent polish, all of which contribute to a clean, lively visual field and consistent light return that the trained eye will immediately recognize, The Natural Sapphire Company presents this gem as a study in material quality and lapidary precision.

The cutting style is faceted, executed as a mixed brilliant regimen that integrates a brilliant crown facet arrangement with a precision oriented pavilion geometry, the cushion outline is softened by slightly rounded corners and carefully calibrated pavilion angles, the cutter has prioritized facet proportions to optimize total internal reflection within the corundum medium, the crown facets serve to disperse incoming light and create defined scintillation, the pavilion facets are angled to capture and redirect light through the crown for maximum perceived brightness, the custom facet architecture produces pronounced contrast between broad flashes of blue and pinpoints of white light, this contrast pattern is a direct outcome of facet size, placement, and the interactive geometry of crown to pavilion, the stone depth as expressed by the 5.03 millimeter thickness relative to the average face diameter emphasizes color saturation, the slightly deeper pavilion supports a richer, more saturated blue while the mixed brilliant approach prevents excessive light leakage by preserving internal reflection pathways, the excellent polish ensures facet junctions are crisp, facet planes are free of nicks and polish lines, and microscopic light scattering at the surface is minimized, these combined cutting decisions yield a sparkle that is both lively and stable across movement, a hallmark of disciplined lapidary technique.

Color and clarity characteristics of this sapphire are integral to its unmatched scintillation, the vivid blue intensity is grounded in the presence of trace iron and titanium within the corundum lattice which produce selective absorption bands in the visible spectrum, the heat treatment historically applied to Ceylon sapphires has been performed to eliminate silk like rutile inclusions and to encourage homogenization of color, this treatment does not obscure the stone s natural pleochroism which manifests as subtle variation in blue depth when the gem is rotated, the very very slightly included clarity grade confirms that inclusions are minute, located at depths or planes that do not disrupt the passage and reflection of light at normal viewing distances, under magnification these inclusions serve as light scattering nuclei that enhance the dynamic scintillation by providing micro contrast without compromising transparency, the overall polish and facet symmetry work in concert with the internal structure to produce a high degree of brilliance, the result is a visual experience where large, lively flashes of vivid blue alternate with sharp, white scintillation, the interplay is amplified by the sapphire s high specific gravity and refractive properties which deliver a dense, saturated visual presence, for clients who appreciate technical excellence The Natural Sapphire Company offers this cushion sapphire as an exemplar of how origin, treatment, and masterful cutting converge to produce a stone with depth of color, mechanical integrity, and a scintillation profile that stands apart, this sapphire is ideally suited for settings that allow the crown to catch light during wear, such as solitaire rings and halo designs, where the engineered facet structure will continue to reveal new facets of brilliance with every movement.
