1.52 Ct. Purple Sapphire from Ceylon (Sri Lanka)

This transparent 1.52 carat radiant shape purple sapphire measures 6.43 by 5.84 by 4.23 mm, presenting a compact and well balanced outline that translates to a depth of approximately 68.9 percent, a proportion that favors both color saturation and strong light return. The gem is cut in a classic radiant style, where a mixed faceting schema yields a lively interplay of broad flashes and pinpoint scintillation, and the trimmed corners provide durability while maintaining a square to slightly rectangular silhouette. Color is graded as medium intensity with a primary purple hue that leans toward a cool lavender in certain light sources, and the stone is described as very slightly included when evaluated at eye level, indicating that it reads as eye clean to most observers while retaining minor internal features that are visible under magnification. This sapphire is untreated, no enhancement, and its origin is Ceylon Sri Lanka, a provenance noted for producing sapphires with refined color and delicate transparency, and The Natural Sapphire Company presents this gem with full disclosure of its natural state and provenance.

The faceting and finish of this piece demonstrate deliberate lapidary strategy to maximize optical performance, with a radiant cut configuration that combines a brilliant style crown to increase sparkle and a more planar pavilion design to concentrate color in the table area, thereby avoiding excessive windowing. The cutter optimized table size relative to overall dimensions to allow a generous face up area while preserving pavilion volume, and the symmetry and excellent polish produce crisp facet junctions and uninterrupted light paths, which enhance both contrast and return. Very slightly included clarity at eye level implies internal features consistent with natural corundum, and because the polish quality is excellent these features do not detract from surface brightness or tactile feel. The result is a gem that harmonizes color, cut, and clarity, providing a controlled balance of face up brilliance and saturated purple tone, a balance that is particularly desirable in a radiant cut sapphire of this size and proportion.

The narrative of how this sapphire came to be is a narrative of time, pressure, chemistry, and motion that unfolded deep within the Sri Lankan crust millions of years ago. Corundum began as aluminum oxide within high grade metamorphic host rocks, crystallizing under elevated temperatures and pressures in environments where silica was relatively low and aluminum was concentrated. Trace concentrations of chromium and vanadium, incorporated into the crystal lattice during growth, modulated the absorption spectrum of the corundum and produced the violet to purple response that characterizes this specimen, while minor amounts of iron and titanium influenced the depth and tone of color at varying growth zones. Over vast spans of geological time uplift and weathering liberated the crystals from their primary veins and gneisses, enabling fluvial transport into alluvial gravels where mechanical rounding and sorting concentrated gem material. It was from such gravels that this rough material was recovered, and subsequent careful planning by experienced cutters preserved the stone without heat or chemical treatment, aligning growth zoning to the table to optimize color distribution and minimize visibility of internal features. The Natural Sapphire Company then completed the work with a precision radiant cut and an excellent polish, producing a finished sapphire that retains a readable geological history, natural color, and exceptional lapidary craftsmanship.
