1.82 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 1.82 carat round blue sapphire presents precise proportions and deliberate craftsmanship, measured at 7.41 x 7.40 x 3.90 millimeters, with an effective depth of about 52.7 percent, a dimension that supports a strong face up presence without sacrificing light return. The stone is fashioned as a mixed brilliant cut, combining a brilliant facet arrangement on the crown with a calibrated pavilion geometry that enhances both scintillation and depth of color. The table and crown angles have been optimized to balance contrast and brilliance, and the excellent polish on all facet junctions produces crisp facet reflections and a lively surface finish. Color intensity is graded as intense, yielding a saturated Ceylon blue that displays vivid medium to deep blue tones when examined face up, and a cooler violet hint in certain lighting. The sapphire is heat treated, a standard and permanent enhancement for Sri Lankan material, applied to improve color saturation and clarity while preserving natural crystal morphology.

Clarity is evaluated as very slightly included at eye level, and the stone contains a suite of internal features that function as unique identifiers and contribute to its character, rather than detracting from its appeal. Fine needle silk and isolated crystal inclusions produce subtle internal texture, while discrete feathers and occasional negative crystal formations create internal light interactions that can be used to match the stone to accompanying documentation. These inclusions influence the stone in predictable ways, softening some facet reflections and creating a layered depth that enhances the perception of color when viewed from multiple angles. For the discerning buyer and the experienced setter, these naturally occurring markers are advantages, aiding provenance tracking and ensuring each example remains a singular specimen. Sourced from Ceylon in Sri Lanka and offered by The Natural Sapphire Company, this sapphire is well suited to a classic solitaire or a refined halo setting, and it will respond well to precision mounting that preserves table visibility and protects the girdle. For collectors who prioritize natural character and technical quality, this 1.82 carat mixed brilliant round sapphire represents a balanced combination of hue, cut, and internal fingerprint that will perform with enduring presence.
