1.13 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.13 carat oval blue sapphire from Ceylon, Sri Lanka, presents a finely balanced combination of weight and proportions, and is offered by The Natural Sapphire Company. The gem measures 6.63 by 5.51 by 3.74 millimeters, producing an average diameter of approximately 6.07 millimeters and a depth percentage of about 61.6 percent. These proportions are consistent with a well executed mixed brilliant oval, where a modest pavilion depth and carefully calibrated crown height work together to optimize the return of light to the viewer. The mixed brilliant faceting integrates a brilliant cut crown with a step influenced or modified pavilion geometry, and this layout leverages both large facets for strong face up sparkle and smaller pavilion facets for controlled scintillation. The result is a stone that reads larger on the finger than its weight might suggest, while maintaining crisp facet architecture and balanced light performance in varied lighting conditions.

Color and clarity are handled with technical precision in this specimen, the body color grading as medium intensity blue, with the classic Ceylon signature of liveliness and a subtle cool undertone that can exhibit faint violet modulation under varied daylight spectra. The medium color intensity ensures the sapphire retains saturation sufficient for presence, without entering into overly dark tones that would impede brilliance. Clarity is graded slightly included at eye level, and the inclusions are consistent with natural growth features, discreet crystal pinpoints and fine needles that do not disrupt the main light pathways. Because the cut prioritizes symmetry and facet junction cleanliness, these minor inclusions remain visually unobtrusive, often masked by facet reflections and windowing behavior inherent to the mixed brilliant layout. The polish is excellent, with smooth facet planes and acute facet junctions that maintain high contrast and crisp reflections, thereby maximizing both the luminous flash and the subtle sparkles that define fine sapphire performance.

This sapphire is unenhanced and entirely natural, with no heat or diffusion treatment applied, a quality distinction that enhances its desirability to collectors and connoisseurs who prioritize original natural material. The combination of a superior mixed brilliant cut, medium color intensity, and excellent polish makes this piece an effective centerpiece for a range of high end settings, and it will read brilliantly in open style bezels, four prong mounts, or halo treatments that accentuate face up size while permitting free light access to the pavilion. For jewelry craftsmen seeking optimal light return, a low profile claw or bezel setting with minimal metal intrusion above the girdle plane will allow the pavilion facets to interact fully with incident light, enhancing both broad flash and pinpoint scintillation. As with all pieces curated by The Natural Sapphire Company, this sapphire is presented with transparent technical data, and it stands out as a well proportioned, naturally colored, and skillfully finished example that will act as the luminous focal point in a bespoke engagement ring, a refined pendant, or as the principal gem in a collector grade suite.
