1.61 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This sapphire began its journey in the alluvial gravels of Ceylon, a region with a long history of producing blue sapphires of notable color and character. The rough crystal was recovered by experienced local miners who work small scale deposits, then transported under careful handling to a regional sorting facility. At that stage the crystal was evaluated for color zoning, clarity windows, and potential yield, and it was selected for cutting because of its strong, consistent blue and good transparency. The decision making at the mine and sorting steps focuses on preserving natural color intensity and minimizing material loss, so the rough was designated for a round, mixed brilliant approach that would maximize both weight retention and optical performance.

The cutting phase defined the stone that is now available from The Natural Sapphire Company, a transparent round sapphire weighing 1.61 carat with dimensions of 7.42 by 7.36 by 4.32 mm. The cutter used a mixed brilliant faceting scheme, combining a faceted pavilion that promotes depth and scintillation with a brilliant style crown that returns light to the viewer. The result is a well balanced pavilion depth and table size that deliver strong face up color and lively facet contrast. The gem presents a vivid color intensity, which remains saturated without appearing overly dark when viewed face up, and the excellent polish enhances surface luster and the crispness of facet junctions. The stone is unenhanced, a factor that preserves natural material integrity and appeals to collectors who prioritize untreated gems.

Clarity was evaluated at eye level and graded as slightly included, meaning small internal characteristics are present but do not materially detract from the visual appeal or the gem's performance in jewelry. These natural inclusions also serve as diagnostic features that support the gem's natural origin and help confirm that no heat or diffusion treatments were applied. Under loupe and microscope the inclusions are consistent with sapphire formation in metamorphic deposits typical of Sri Lanka. The balanced proportions, together with the mixed brilliant cut and the excellent polish, allow the sapphire to display a lively interaction of light, contributing to a refined face up appearance. Photographs of the stone loose and mounted provide a realistic representation of scale and color, and when set the gem maintains a vivid presence that suits both classic and contemporary settings.

From final quality control to market placement, The Natural Sapphire Company coordinated the logistics, documentation, and presentation that accompany this gemstone. The stone underwent physical measurements, weight verification, and photographic documentation, and its origin and treatment status were recorded in our internal provenance files to ensure traceability. Packaging and secure transport followed best practices for precious gemstones, and the sapphire is offered with clear specifications regarding carat weight, dimensions, cut style, clarity grade, polish quality, color intensity, treatment status, and origin. For customers considering settings, this 1.61 carat round sapphire pairs well with carefully proportioned mounting styles that allow light to reach the pavilion, and it responds well to white, yellow, or rose metals depending on desired contrast. Care recommendations are straightforward, gentle cleaning with mild detergent and a soft brush, and routine inspection of any mounting to protect the stone and setting. This sapphire represents a measured combination of provenance, craftsmanship, and natural color, presented with the documentation and handling standards that The Natural Sapphire Company maintains for all of its untreated sapphires.
