2.74 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This transparent 2.74 carat cushion shape blue sapphire measures 9.40 x 6.78 x 4.38 mm, presenting a well balanced table to depth relationship that yields an approximate depth percentage of 54.1 percent, ideal for a mixed brilliant faceting scheme. The cutting combines a modified brilliant crown with a precise step influenced pavilion, a faceting style chosen to emphasize both scintillation and color saturation in a non round outline. Clarity is graded very very slightly included evaluated at eye level, indicating only minor internal features visible under close inspection, and the stone benefits from an excellent polish that produces crisp facet junctions and strong light return. Color is described as vivid intensity, a hallmark of fine Ceylon material that shows dynamic blue saturation across crown facets while often displaying subtle pleochroic shifts when rotated. The sapphire has been heat treated, a stable and industry accepted enhancement that improves color homogeneity and reduces silk without compromising the structural integrity of corundum. As corundum this gem sits within a refractive index range typical of sapphire, and its specific gravity and hardness make it exceptionally durable for everyday wear, qualities highlighted by the precise mixed brilliant cut which maximizes optical performance while preserving weight and brilliance for modern jewelry designs. The Natural Sapphire Company offers this gem with full technical details to support informed selection and setting decisions.

The narrative of this sapphire begins deep in the crust of Sri Lanka, where aluminum rich sediments and basaltic intrusions were subjected to heat and pressure over millions of years, promoting the crystallization of aluminum oxide into corundum within metamorphic lenses and veinlets. Trace amounts of iron and titanium introduced during growth provided the blue chromophores, and fluctuating conditions produced the vivid saturation and occasional zoning that give each Ceylon sapphire its character. Over geological time weathering liberated these crystals into alluvial gravels where natural tumbling smoothed rough faces and concentrated the finest examples in river bends and ancient terraces, locations where local miners have recovered gem quality stones for generations. When brought to the lapidary studio, this particular crystal was evaluated for orientation, and a mixed brilliant strategy was chosen to balance color, weight retention, and maximum light performance, followed by meticulous facet cutting and hand finishing to achieve the excellent polish and precise symmetry you see today. The Natural Sapphire Company stands behind the provenance and craftsmanship of this stone, and our team is available to advise on mounting options that will showcase its vivid blue color and exceptional optical properties.
