1.46 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.46 carat oval blue sapphire measures 7.71 x 6.27 x 3.57 mm, presenting a classic Ceylon proportion that balances table size and depth for optimal light performance. The cutting style is faceted, executed in a mixed brilliant cut that combines a brilliant facet arrangement on the crown with step influenced pavilion faceting, producing a controlled interplay of scintillation and color depth. Clarity is graded slightly included at eye level, indicating inclusions that are visible under careful unaided inspection but that do not materially disrupt the clean passage of light through the stone. Color intensity is assessed as intense, with an even distribution of blue across the table and facets, and polish is graded excellent, reflecting a high level of lapidary finish and attention to facet junction integrity and surface smoothness. The stone has been subjected to standard heat treatment, a stable and long established enhancement that optimizes hue and saturation by reducing brown and green overtones commonly present in rough Ceylon material, and this treatment is fully disclosed by The Natural Sapphire Company.

In hue and tone this Ceylon sapphire exhibits a vivid true blue with a slightly lighter tone and a brighter, more electric saturation than the deep velvety cornflower blues typical of Kashmir sapphires. Compared to classic Kashmir material, which often sits at a medium to medium dark tone with a powdery silk derived diffusion of light, this stone reads as more lively and transparent, delivering greater brilliance at the table and more facet scintillation. Relative to Burmese and Mogok sapphires the hue here is less purplish and more purely blue, Burma material can skew toward a richer, more royal blue with warmer undertones, while this Ceylon example maintains a cooler neutrality that enhances perceived clarity. Against Madagascan sapphires the comparison is closer, as Madagascan stones frequently display vibrant, highly saturated blues similar to high quality Sri Lankan material, though Madagascar can trend toward slightly stronger saturation and deeper tone. Australian sapphires characteristically show a darker, inky, or steely blue tone, often with higher tone and less transparency, and Montana sapphires tend to skew toward teal or greenish blue hues. Placed on that spectrum, this 1.46 carat Ceylon sapphire occupies a desirable position, offering intense saturation with a medium to medium deep tone that maximizes brilliance without becoming inky, and its hue leans toward pure blue rather than blue with strong secondary modifiers.

From a craftsmanship perspective the mixed brilliant cut is purposeful for a stone of these dimensions, the crown facet architecture creates numerous small facet planes that enhance scintillation and lively return of white light, while the pavilion design uses step influenced geometry to maintain color concentration and to avoid dark windowing near the culet. The cutter has emphasized symmetry, maintaining even facet sizes and clean girdle proportions to enable consistent light performance in ring and pendant settings. The excellent polish indicates meticulous final surfacing with minimal polish lines, which preserves optical clarity and allows the intense color to read cleanly through the table. Inclusions present as part of the slightly included clarity grade are consistent with typical Sri Lankan sapphires, often manifesting as fine silk, feather type inclusions, or minute crystal needles, and these internal features can act to diffuse light subtly, contributing to a gentle velvety effect without materially reducing brilliance. Heat treatment has been applied to stabilize color and improve tone uniformity, a standard enhancement in the trade that delivers predictable, durable results when disclosed and handled properly by experienced setters.

This sapphire is an excellent candidate for a classic solitaire ring or a three stone commission where the mixed brilliant cutting will interact with adjacent diamonds to create lively contrast. Its size and dimensions allow for secure bezel or prong settings, and the stone responds well to light, revealing a lively play of blue across crown facets under varied lighting. The Natural Sapphire Company stands behind the provenance and full disclosure of origin and enhancement, and our lapidary partners apply precision cutting and polishing techniques to present this Ceylon gem with both technical excellence and aesthetic balance. For collectors who seek a sapphire with vivid, pure blue hue, intense color intensity, and the transparent brilliance that distinguishes fine Sri Lankan sapphires from darker or more muted sources, this 1.46 carat oval is a technically refined and visually compelling choice.
