2.10 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This description concerns a transparent blue sapphire of 2.10 carats, radiant shape, with dimensions of 7.32 x 6.48 x 4.61 mm. The gem presents a radiant cut that combines crisp pavilion facets with a broad table to maximize scintillation and visual depth, and an excellent polish that produces clean facet junctions and smooth reflective planes. Clarity is graded as very very slightly included, evaluated at eye level, and the stone displays a light color intensity that conveys a cool, airy blue. No enhancement has been applied to this sapphire, and its provenance is Ceylon, Sri Lanka, a region long recognized for producing stones with a distinctive combination of brightness and refined hue. The Natural Sapphire Company has cataloged this gem with attention to its measured proportions and visual behavior under standard viewing conditions, ensuring that the specifications reflect the stone seen in hand and in photography.

The narrative of formation for this sapphire begins deep below the surface of the crust, where aluminum rich protoliths encountered conditions of elevated temperature and pressure during regional metamorphism, a process that took place millions of years ago. In such an environment, aluminum oxide crystals nucleated and grew in the presence of trace elements such as iron and titanium, the latter pair influencing the absorption features that yield blue coloration through intervalence charge transfer and related mechanisms. Over long intervals, slow crystal growth permitted the development of a coherent crystal lattice with very low concentrations of disruptive defects, yielding the transparency and clarity observed today. Fluids circulating through metamorphic rocks contributed to element transport and sometimes promoted the growth of larger crystals, and subsequent geological pulses altered the surrounding matrix while leaving isolated corundum crystals intact. Later erosional processes liberated many Sri Lankan sapphires from their primary host rocks, concentrating them in alluvial gravels and making them accessible to miners, and some stones retained morphological evidence of that history through surface features and internal growth structures that can be read by an experienced gemologist. This particular stone, with its balanced color and minimal inclusions, records a lengthy and complex geological history, from deep crustal synthesis to uplift and exposure, before the lapidary work that produced its current radiant cut.

Viewed as an object of design and measurement, this sapphire offers predictable optical performance and practical dimensions for a variety of settings, and the 7.32 x 6.48 x 4.61 mm proportions are well suited to receive secure mounting while maintaining visible table area and optical return. The radiant cut emphasizes the gem's internal brightness, and the light color intensity favors settings in white metals that preserve the stone's cool tone, although bench considerations and personal preference may suggest alternative metal choices. Given the clarity grade of very very slightly included at eye level, examination under magnification will reveal minor internal characteristics that do not interrupt the gem's overall transparency, and the absence of enhancement confirms that the color and clarity are natural attributes of the material. The Natural Sapphire Company includes provenance and treatment information with each gem that leaves our inventory, and this sapphire is presented with its measured dimensions and observed characteristics to support informed selection and design.
