1.05 Ct. Bluish Green Sapphire from Ceylon (Sri Lanka)

This 1.05 carat radiant shape bluish green sapphire from Ceylon, offered by The Natural Sapphire Company, is described with precision to satisfy the technically minded collector, the dimensions are 7.30 by 4.45 by 3.36 mm, the length to width ratio is approximately 1.64, and the pavilion depth yields an overall depth of approximately 57.2 percent, metrics that speak to a deliberately proportioned stone optimized for both table brilliance and face up color saturation. The radiant cut employed here combines the geometric economy of step facets with the light dispersion properties of brilliant style facets, producing a faceting architecture that balances scintillation with color depth, the polish is graded excellent, resulting in crisp facet junctions and mirror like facet planes that transmit light with minimal surface diffusion. Clarity is very very slightly included, evaluated at eye level, these inclusions are negligible in their impact on transparency, and they act at times as subtle internal identifiers that confirm natural origin, the stone has been heat treated, which is standard practice to stabilize and enhance the medium intense bluish green hue, the origin is Ceylon Sri Lanka, a historic source noted for producing sapphires with nuanced cool tones and strong conservation of clarity.

From a cutting and gemological standpoint the radiant geometry has been executed to emphasize the stone s innate pleochroism, the mixed facet arrangement on the crown and pavilion controls the directional transmission of the blue and green color components so that the stone presents a dynamic, controllable color face up as the viewing angle or mounting changes. The relatively elongated rectangular outline at a one point six four ratio makes this gem particularly well suited to east west and bezel set designs that exploit the length for visual impact, at the same time the depth percentage sits in an ideal range for maximizing return of light and avoiding a visually heavy or overly dark table, the excellent polish enhances contrast between the brilliant style facets and the step zones, creating crisp flashes that offset the medium intense color and produce a perceived increase in saturation without tipping into opacity. The material s transparency and eye clean grade allow for tighter facet junctions and a slightly more aggressive crown angle than one might adopt for heavily included rough, the result is a stone whose faceting language reads as both modern and technically faithful to the optical behavior of corundum, placing emphasis on directional light performance and color balance rather than sheer dispersion alone.

When set against famous historical sapphires this Ceylon radiant delivers a different but complementary set of virtues, while the Logan Sapphire commands attention for its extraordinary cornflower blue mass and the Star of India impresses with its cabochon display and chatoyancy, this bluish green radiant captures an understated historical narrative of Ceylon material that has long been prized for its subtlety and clarity rather than loud saturation alone. The medium intense bluish green sits between classic royal blue and teal, creating a palette that echoes the nuanced green tinges recorded in prized Ceylon examples that have populated royal collections, yet the faceting and proportions here introduce a modern interpretative advantage, the radiant cut increases apparent brightness and retains color integrity in smaller sizes where traditional step cuts can sometimes lose lively return of light. For the technically minded buyer the unique value lies in the intersection of provenance, measured proportions, and faceting strategy, the heat treatment is disclosed and consistent with trade norms for Ceylon sapphires, the eye level clarity and excellent polish provide a clean optical field for appraisal and setting, and the elongated radiant outline opens a spectrum of design choices from knife edge solitaires to architectural three stone mounts. The Natural Sapphire Company stands behind the gem s documented origin and craftsmanship, and this stone will appeal to collectors and connoisseurs who prioritize precise proportions, controlled pleochroism, and the historic character of Ceylon corundum.
