3.31 Ct. Green Sapphire from Ceylon (Sri Lanka)

This 3.31 carat green sapphire presents a balanced combination of substance and wearable proportions, offered by The Natural Sapphire Company. The stone is cut into a classic cushion shape, measuring 7.74 by 7.28 by 6.68 millimeters, dimensions that make it suitable for a broad range of custom settings. The mixed brilliant cut ensures lively internal reflection while preserving the rounded square outline that is the hallmark of the cushion form. Originating from Ceylon Sri Lanka, the sapphire exhibits the geological character and stable crystal quality associated with that locality. These objective parameters, including exact weight and precise measurements, support confident design planning for rings, pendants, or bespoke pieces in which the gem will serve as the principal focal point.

Color and clarity details are central to understanding the visual behavior of this sapphire in finished jewelry. The gem displays a dark color intensity in a transparent green tone, lending depth and a refined presence when mounted. Clarity is graded very slightly included, evaluated at eye level, which indicates minor inclusions that do not detract from the overall appearance under normal inspection. The pavilion and crown facets show an excellent polish, contributing to crisp facet junctions and consistent light return from the mixed brilliant arrangement. The sapphire has undergone a standard heat treatment, a widely accepted and stable enhancement that optimizes color saturation and clarity, while preserving natural origin and structural integrity.

The cushion shape and the specific size of this 3.31 carat stone make it particularly well suited to custom jewelry work. The nearly square outline with soft corners provides a versatile platform for a variety of mounting styles, from low profile bezel settings that emphasize clean lines, to classic prong settings that maximize sparkle and allow light to enter the stone from multiple angles. At approximately 7.7 millimeters across, the gem reads with presence on the hand without requiring an overly large setting, making it ideal for single stone engagement rings, statement pendants, or a prominent central piece in a cocktail style design. The mixed brilliant cut enhances fire and scintillation in direct light, while the cushion silhouette offers a traditional aesthetic that complements both contemporary and vintage inspired designs.

From a practical design and maintenance perspective, this sapphire is advantageous for custom applications. The depth of 6.68 millimeters gives adequate pavilion material for secure bezel and prong work, reducing the risk of overexposure or structural compromise during setting. The dark green hue pairs well with a range of metal choices, including warm yellow gold which emphasizes the richness of the color, cool white metals which present a modern contrast, and rose gold which lends a softer, more romantic tone. Accent stones may be used to increase perceived size and contrast, for example white diamonds to enhance brilliance, or lighter green sapphires for tonal harmony. The Natural Sapphire Company can provide gemological documentation and recommendations for setting tolerances, and our team is available to advise on metal choice, mounting style, and ring shank proportions to achieve a durable and visually balanced finished piece. Routine care is straightforward, limited to periodic professional cleaning and standard precautions against hard knocks, reflecting the inherent durability of corundum family gems.
