0.52 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This specimen is a transparent 0.52 carat round sapphire, measured at 4.96, 4.95, 2.77 mm, cut as a mixed brilliant. The gem displays vivid color intensity with a pure deep blue hue and an excellent polish that produces a high luster across the crown facets. Clarity was evaluated at eye level as very very slightly included, indicating that inclusions are minimal and do not interrupt the visual face up appearance or the light return from the pavilion. Enhancement by controlled heat treatment has been applied to stabilize and deepen the blue without compromising the stone structure, and the material originates from Ceylon Sri Lanka, a source renowned for producing lively, richly saturated sapphires that balance tone and brilliance. The weight and proportions are well matched for a round gem of this class, and the overall transparency and vivid saturation are immediately apparent to the trained eye.

The mixed brilliant execution is purposeful, combining a brilliant style crown with a faceted pavilion that maximizes scintillation while preserving color saturation. The cutter retained a moderate depth of approximately fifty six percent, a proportion that favors a strong face up presence and broad flash scintillation rather than excessive windowing or light leakage. Crown facet geometry emphasizes smaller star and bezel facets to break light into crisp pinpoint flashes, while the pavilion facet arrangement yields broad contrast areas that enhance perceived depth of color. Excellent polish on each facet junction ensures sharp light return and minimizes surface grain, which is especially important in a stone graded very very slightly included, because internal features remain unobtrusive and the gem presents as effectively eye clean. The mixed brilliant approach also serves to distribute color evenly across the table, preventing undesirable color zoning and allowing the vivid saturation to read consistently even in varied lighting conditions.

For buyers seeking a statement piece the combination of vivid color intensity, high transparency, and eye level very very slightly included clarity makes this 0.52 carat Ceylon sapphire unusually effective for high impact settings. Although modest in carat weight, the optimized proportions and strong saturation give a perceptual presence larger than the weight alone would suggest, so the stone excels as a solitary focal point in a classic four or six prong solitaire, where minimal metal coverage preserves the face up area, or as the centerpiece of a halo setting in which surrounding diamonds amplify the sapphire sited intensity. For designs requiring protection in everyday wear a precision bezel can be specified, turned inward slightly to avoid obscuring the table and to maintain the stone face up prominence. The Natural Sapphire Company stands behind the origin and the workmanship of this material, and our lapidaries have finished this gem to accentuate its natural Ceylon character while respecting the integrity of the rough, making it an excellent choice for a technician or connoisseur who values detailed cut performance, precise proportions, and vivid natural color in a statement quality sapphire.
