0.66 Ct. Yellowish Green Sapphire from Madagascar

This transparent 0.66 carat cushion shape yellowish green sapphire measures 6.09 by 4.36 by 2.49 mm, and features a mixed brilliant cut that balances scintillation and face up color. Graded as very very slightly included at eye level, this gem presents minimal internal features that do not distract from its transparency or sparkle when set. The light color intensity is subtle and elegant, allowing the yellowish green hue to read as fresh and versatile under a range of lighting conditions. Polish is excellent, contributing to lively light return across the table and crown facets, and the stone is without enhancement, which significantly increases its desirability to collectors and connoisseurs who prioritize natural, untreated material. This sapphire is from Madagascar, an origin known for producing sapphires with distinctive and appealing color variations, and The Natural Sapphire Company stands behind its provenance and quality for buyers seeking documented, responsibly sourced gems.

For an educated buyer assessing rarity and long term value, this specimen is notable in both size and color when compared to the broader market of sapphires. Yellowish green sapphires are far less common than traditional blue or even pure green stones, and an untreated, eye clean example under one carat in a classic cushion cut is uncommon. The combination of a pleasing light intensity, transparent body, and a mixed brilliant facet architecture means the gem displays both color and brilliance without the need for enhancement, a feature that enhances its scarcity. In practical terms, at 0.66 carat and with the compact yet substantial dimensions listed, this sapphire adapts beautifully as a center stone in intimate engagement settings or as a refined accent in bespoke jewelry, while also appealing to collectors seeking pieces with clear provenance and minimal treatment. If rarity of color, confirmation of no enhancement, and a reliable origin matter to you as a buyer, this Madagascan yellowish green cushion sapphire offered by The Natural Sapphire Company represents a compelling balance of aesthetic charm, gemological integrity, and collectible appeal.
