3.30 Ct. Blue Sapphire from Ceylon (Sri Lanka)

One beautiful transparent 3.30 carat emerald cut blue sapphire from Ceylon Sri Lanka is presented by The Natural Sapphire Company, dimensions 9.26 x 7.62 x 4.66 mm, clarity grade eye clean as evaluated at eye level, color intensity classified as intense, polish graded excellent, enhancement by controlled heat treatment. The stone is cut in a classic emerald cut configuration, characterized by broad concentric step facets on the crown and pavilion, a relatively large table, and gently truncated corners that reduce chipping risk while creating a geometric, architectural face up. The combination of weight and footprint yields a depth ratio of approximately 55 percent, which balances face up spread with internal light return, preserving saturation while avoiding excessive windowing. The heat treatment applied is a standard and widely accepted enhancement that stabilizes and deepens the blue hue typical of fine Sri Lankan sapphires, and the excellent polish executed by experienced lapidaries ensures crisp facet junctions and maximum surface luster.

From a faceting and light performance perspective, the emerald cut step faceting emphasizes color and orientation dependent flashes rather than dispersed brilliance typical of brilliant cuts, producing broad reflective planes and a hall of mirrors effect. The crown comprises stepped facets that act as reflecting planes, channeling incident light into broad bands of blue, while the pavilion steps return color in wide flashes instead of pinpoint scintillation. The stone is effectively eye clean, which minimizes scattering by inclusions and allows the step facets to project unbroken color planes. The relatively shallow to medium depth permits an ample table that reads as a broad color window, while the carefully controlled pavilion angles reduce light leakage and preserve saturated tonality. The cutter preserved symmetry and facet alignment to accentuate parallel light return, and the excellent polish enhances luster and tactile smoothness, contributing to perceived quality and wear comfort.

Under varied lighting conditions the sapphire presents a versatile and compelling personality. In bright natural daylight and under north light the stone reads as a vivid, intense blue with slight notes of cornflower blue at certain angles, the step facets producing broad, velvety flashes and a strong face up color that appears both saturated and evenly distributed. In direct sunlight the stone displays more pronounced contrast between the step planes, producing alternating bands of deep blue and bright reflective highlights, which creates dynamic visual interest without turning to high fire. Under warm incandescent lighting the blue leans marginally towards a richer, slightly warmer tone, while maintaining overall intensity, making the gem appear sumptuous in evening settings. Under cool white LED light the sapphire shows crisp, highly saturated blue with precise reflective planes, and the step facets produce strong mirror like luster that reads as both lively and controlled. In soft, diffuse indoor lighting the stone becomes more velvety and uniform, highlighting the purity of the hue and the eye clean clarity, while in low light the sapphire retains depth and presence due to its intense color, rather than relying on scintillation to attract attention. The material exhibits subtle pleochroism, yielding minor shifts from pure blue to slightly purplish blue when the stone is tilted, a trait that contributes to visual complexity rather than detracting from color consistency.

When considering mounting and use, the emerald cut 3.30 carat sapphire benefits from settings that allow light to enter the pavilion and escape through the crown, preserving the step facets function and maximizing perceived color. Open four or six prong mounts, gallery openings, or partial bezel designs that leave the pavilion accessible are recommended to avoid muffling the steps and to preserve the hall of mirrors effect. White metals will emphasize the purity and intensity of the blue, while warm yellow metals will introduce a subtle warming effect on the overall tone if a slightly richer appearance is desired. For daily wear the inherent toughness of corundum provides excellent durability, and the truncated corners of the emerald cut reduce vulnerability to edge chips. This sapphire has been cut and finished by seasoned craftsmen working with The Natural Sapphire Company, who matched cut geometry to inherent crystal orientation to maximize color and minimize windowing, and who applied heat treatment in a controlled manner to enhance the stone without compromising structural integrity. For collectors and connoisseurs who prioritize precise faceting, stable intense color, and a stone that performs across a wide range of lighting environments, this emerald cut Ceylon sapphire is an exemplary choice, and our gem specialists at The Natural Sapphire Company are available to advise on settings and to provide comprehensive documentation.
