4.02 Ct. Bluish Green Sapphire from Madagascar

One beautiful transparent 4.02 carat cushion shape bluish green sapphire is offered by The Natural Sapphire Company, with precise proportions of 9.02 x 7.71 x 6.00 mm. The gemstone is faceted in a mixed brilliant cut, a design that combines a faceting scheme for strong light return with a pavilion structure that deepens color, creating lively scintillation alongside saturated tone. The clarity grade is very slightly included evaluated at eye level, indicating that any internal features are minor and do not materially distract from the gem when viewed without magnification. Color intensity is described as dark, which gives the stone a concentrated, velvety presence, and the polish is excellent, reflecting careful finishing and sharp facet junctions that optimize brilliance. This sapphire has been heat treated, a common and stable enhancement that improves color and overall appearance while being fully disclosed, and it originates from Madagascar, a source increasingly prized for sapphires that show complex green and blue interactions.

For the educated buyer this stone represents a compelling balance of rarity and practicality. A 4.02 carat transparent sapphire of cushion shape with very slightly included clarity at these dimensions is uncommon, and the mixed brilliant cut was selected to enhance both visual depth and face up sparkle, making the rich, bold bluish green color read as a symbol of personal power and distinction. The dark intensity lends a sophisticated and assertive character that works equally well as a centerpiece in a bespoke engagement setting or as an accent for high jewelry, and the inherent hardness of sapphire ensures excellent durability for everyday wear when set with appropriate protection. The natural origin in Madagascar contributes to the gemological story and market interest, and the disclosed heat treatment is consistent with industry standards, maintaining long term stability. The Natural Sapphire Company can provide additional images, specific facet maps, and mounting recommendations to help translate this stone into a finished piece that reflects individual style and status, and our specialists are available to discuss how this sapphire can serve as a lasting emblem of distinction.
