1.55 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This pear shape blue sapphire weighs 1.55 carat, and measures 10.53 by 4.86 by 4.13 millimeters, giving it a length to width ratio of approximately 2.17 to 1 and a depth that translates to about 53.7 percent of the average diameter. The stone is transparent, with a mixed brilliant cut executed to precise proportions, and an excellent polish that produces sharp facet junctions and lively facet contrasts. Clarity is graded as very very slightly included, evaluated at eye level, meaning that the gem presents only minute, well healed mineral inclusions and fine silk that do not interrupt transparency or the visual flow of color when set. Color is vivid in intensity, a deep saturated blue characteristic of fine Ceylon material, with a balanced distribution of tone across the pear outline and no significant color zoning. The piece has undergone responsible heat treatment to stabilize and intensify color, a standard and durable enhancement applied to natural corundum, and is fully disclosed as part of The Natural Sapphire Company presentation.

The journey from mine to market begins in the gem gravels of Sri Lanka, where artisanal and small scale miners recover sapphire bearing material from weathered alluvial deposits. The rough for this sapphire was selected for its saturated blue and excellent transparency, and it passed The Natural Sapphire Company inhouse sorting protocols that prioritize color homogeneity and clarity potential. The cutter then orientated the rough to preserve weight while optimizing the pear outline, choosing a mixed brilliant schema that layers a faceted brilliant style crown over a precisely proportioned pavilion. This approach concentrates return of saturated blue through the table, while the modified pavilion geometry controls light leakage and minimizes windowing. Cutting decisions included a medium to slightly raised crown to enhance depth of color, and carefully balanced table dimensions to allow scintillation without sacrificing the stone into a visually flat plane. Heat treatment was applied prior to final polishing to reduce microscopic silk and to bring forward the vivid blue, followed by a meticulous multi stage polishing process that achieved an excellent polish and crisp facet symmetry.

In hand the sapphire demonstrates the attributes sought by knowledgeable buyers, showing strong color saturation with excellent transmission and lively facet play when rotated under light. The very very slightly included clarity grade means the stone can be set with minimal design concealment, making it ideal for an elegant solitaire pendant or an elongated ring profile where the pear silhouette reads as a refined drop. Technical buyers will appreciate the calculated length to width proportion that lengthens the finger, the mixed brilliant faceting that balances brilliance with color retention, and the stable heat treatment disclosure that is consistent with trade best practice. The Natural Sapphire Company stands behind the provenance and the craftsmanship, offering detailed reports on origin, enhancement, and the cutting rationale upon request, and recommending settings that protect the pointed end of the pear while showcasing the vivid Ceylon blue that defines this exceptional 1.55 carat gem.
