2.12 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 2.12 carat Ceylon blue sapphire presents as a precision executed cushion shape, with exact measured dimensions of 7.43 by 7.40 by 3.94 millimeters, and a depth approximately 53 percent of the average girdle diameter. The cutter has employed a faceted mixed brilliant style, combining a brilliant crown pavilion geometry designed to maximize scintillation with a controlled pavilion architecture that deepens saturation and preserves strong face up color. The near square length to width ratio of 1.004 produces balanced light performance across the table, and the excellent polish across all facets delivers crisp facet junctions and strong facet contrast. The stone displays tight symmetry in its crown and pavilion alignment, a moderately sized table proportioned to emphasize both brilliance and color, and a well executed girdle profile that supports secure setting without compromising visual appeal.

Color and clarity dynamics set this sapphire apart from typical Ceylon material of comparable size. The gem exhibits vivid color intensity, a hue dominated by pure blue with a subtle depth that reads as regal and saturated when viewed face up under standard viewing conditions. The tone sits in the medium dark range, and saturation is robust, producing a vivid classification rather than the more common medium or medium strong examples from the same origin. At eye level the stone grades as eye clean, with no inclusions evident to unaided viewing, which is a notable quality attribute for a natural sapphire of this carat weight from Ceylon. Pleochroic behavior is restrained and favorable, showing consistent blue across viewing angles, which reflects both the natural crystal orientation and the cutter s choice to orient the pavilion to optimize color consistency. The gem has been heat treated, a widely accepted and stable enhancement in sapphire trade practice, applied to improve crystal clarity and to deepen color saturation, and the treatment has been executed without over diffusion, preserving the natural corundum character and clarity.

From a lapidary and gemological perspective this item is rare in two complementary ways. First, in terms of size, a 2.12 carat specimen in a well balanced cushion proportion is uncommon for high quality Ceylon sapphires, where many fine examples tend to be either smaller with saturated color or larger with trade off in clarity or tone. Second, the vivid color intensity combined with an eye clean clarity grade is an infrequent combination at this carat weight for Sri Lankan material, making this stone a distinct specimen for collectors and high end jewelry commissions. The mixed brilliant faceting has been chosen deliberately to present both strong return of white light and concentrated color flash, so the gem delivers both lively scintillation and a deep steady body color, which is a technical achievement in cutting when working within the natural crystal zoning and inclusional framework common to corundum.

The Natural Sapphire Company presents this sapphire with full technical disclosure, and we stand behind the cutting craftsmanship and provenance information provided. For setting and design considerations the stone s cushion proportions and robust pavilion depth make it versatile for both low profile four prong settings where the pavilion contributes to visual depth, and for more open gallery designs that allow light to enter from multiple angles, enhancing brilliance without diminishing the vivid body color. For bespoke commissions our gem cutters can advise subtle reorientation to further optimize face up tone for specific mountings, or recommend complementary accent stones and metal choices to enhance perceived color intensity. Heat treatment details and origin are disclosed as part of our standard documentation, and we invite serious buyers to request additional imagery under varied lighting conditions or to discuss independent laboratory documentation.
