2.13 Ct. Bluish Green Sapphire from Ceylon (Sri Lanka)

This stone is a transparent 2.13 carat oval bluish green sapphire from Ceylon Sri Lanka, presented by The Natural Sapphire Company. It measures 8.54 millimeters by 6.87 millimeters by 4.29 millimeters, with a mixed brilliant faceting style, an eye level clarity grade of very slightly included, intense color intensity, and an excellent polish. Enhancement has been performed by heat treatment, which is a standard and stable practice that refines tone and clarity without compromising the material integrity. The combination of weight and dimensions yields a gemstone with an elegant face up presence that reads larger than the carat weight alone might suggest, ideal for an appointment ring that benefits from a balanced spread and lively depth.

The mixed brilliant cut has been executed to marry the scintillating return of a brilliant crown with the controlled light behavior of a modified pavilion, delivering strong face up brilliance while preserving color saturation. The pavilion depth at 4.29 millimeters produces a depth proportion of approximately 55.7 percent, which sits in a favorable range for oval sapphires, reducing the tendency toward windowing while maintaining an optimal light path for internal reflection. The crown faceting shows precise facet junctions and symmetry designed to break up light into flashes, while the pavilion facets guide light back through the table with minimal leakage. The result is a lively yet deep visual effect, where pinpoint flashes coexist with broad color fields, allowing the intense bluish green hue to read consistently under varied lighting, and to display subtle pleochroic shifts that are characteristic of corundum.

From a clarity and treatment perspective, the designation very slightly included at eye level indicates that inclusions are minimal, typically fine feathering or pinpoint crystals that do not materially interrupt light transmission or structural stability. In practical terms this means strong transparency and clean visual appeal in hand and in settings, particularly when set with well proportioned girdle engagement. The excellent polish enhances facet crispness and increases apparent luster, which amplifies the sensation of depth and color saturation. As a Sri Lankan origin sapphire, the stone exhibits a trace element signature that commonly includes iron and titanium, which contribute to its bluish green orientation and intense saturation, while heat treatment has been applied to refine tone and remove minor silk without altering the fundamental natural character. These factors together produce a robust, attractive, and predictable gem for everyday wear.

For an engagement ring, this sapphire is an outstanding option because it couples desirable optical performance with practical durability. Corundum rates nine on the Mohs hardness scale, providing excellent wear resistance for a ring that will be worn daily, and the 2.13 carat weight provides a strong presence on the finger while remaining comfortable and wearable. Design choices that maximize the oval outline and color delivery include a four or six prong open head to permit light circulation, a low profile bezel to protect the girdle for active lifestyles, or a halo mounting to increase perceived size and to accentuate the blue green saturation through refracted white sparkle. East west orientation can emphasize the stone length for tapered hands, while a classic north south setting preserves a timeless silhouette. At The Natural Sapphire Company we can advise on pavilion clearance, bezel height, and prong placement to minimize shadowing and to ensure that the very slightly included clarity remains unseen in typical viewing conditions. We also offer bespoke mounting services and professional care guidance to maintain polish and color over time, making this Ceylon sapphire both a technically refined choice and an emotionally resonant engagement center stone.
