2.21 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 2.21 carat round blue sapphire presents itself as a textbook example of precision cutting and vivid natural color, offered through The Natural Sapphire Company. The gem measures 7.38 by 7.32 by 5.09 millimeters, with a faceted mixed brilliant cutting style that balances the optical strengths of both step and brilliant facet systems. The transparent material displays a vivid color intensity within the blue spectrum, and the surface finish is described as excellent polish, which enhances both contrast and light return. The stone is heat treated, which is the established enhancement for many natural sapphires, and the origin is Ceylon Sri Lanka, a source long prized for its ability to produce lively and saturated blue tones. Clarity is graded as slightly included when evaluated at eye level, a grade that communicates visible internal characteristics without materially compromising the overall transparency and face up appeal.

The mixed brilliant cut executed on this round outline has been calibrated to maximize face up color and scintillation, while preserving strong overall brilliance. The crown facet arrangement combines a modest crown angle with a well proportioned table plane to create a pattern of bright flashes and controlled dark areas that emphasize the deep blue tone. The pavilion uses a modified brilliant layout to channel light back through the crown, producing a dynamic interplay between return brilliance and color saturation. With overall dimensions that produce an approximate depth ratio of sixty nine percent the faceting depth is slightly generous, a proportion that favors color concentration in corundum without unduly sacrificing light return. Facet junctions are crisp and symmetrical, and the stone exhibits excellent symmetry through its round outline, attributes that contribute to an even distribution of brilliance and a balanced face up appearance.

Internal characteristics are consistent with natural corundum and present as minor features that are localized and do not interrupt the gemological integrity of the material. The clarity grade of slightly included evaluated at eye level indicates that small inclusions are visible under direct inspection, yet the sapphire remains effectively transparent and lively. Heat treatment has been applied to enhance chroma and to stabilize hue, a common and accepted practice in the trade that can reduce silk and improve the evenness of blue saturation. From an optical perspective this sapphire shows the pleochroic behavior typical of corundum, with subtle variations between slightly lighter and slightly deeper blue tones when rotated under directional light, an effect that adds depth and complexity to its visual character. The refractive properties of corundum contribute to strong light performance, and with the superb polish on this example surface reflections are clean and mirror like, accentuating both brilliance and the intense blue face up color.

As a center stone this sapphire is particularly well suited to settings that allow light to interact with the pavilion and crown, because the mixed brilliant cut rewards thoughtful mounting with lively scintillation and deep saturated color. The stone photographs and appears to sit prominently when shown at finger scale, making it ideal for solitaire engagement rings, classic halo designs, or bespoke settings that emphasize a single dominant blue center. The slightly deeper proportions provide rich color that reads elegantly in both white metal and warm metal settings, and the durable corundum composition provides excellent wearability for everyday jewelry. The Natural Sapphire Company stands behind the sourcing and detailed presentation of this gem, and additional high resolution imagery and gemological assessment can be provided on request to assist in design planning and verification. For buyers seeking a sapphire where exceptional cut and brilliant face up performance make the stone a true centerpiece, this 2.21 carat Ceylon blue sapphire offers a compelling combination of color intensity, cutting precision, and finishing quality.
