1.64 Ct. Yellowish Green Sapphire from Tanzania

This 1.64 carat oval yellowish green sapphire presents an elegant balance of size, color, and craftsmanship, making it a compelling choice for an engagement ring. The gem measures 7.31 x 6.24 x 4.36 mm, a proportion that offers a refined presence on the finger while remaining comfortable for daily wear. Cut as an oval with a mixed brilliant facet arrangement, it combines the lively light return of brilliant cutting with the depth and clarity control of step facets. The intense color intensity gives the stone a vivid and memorable appearance, and the excellent polish enhances surface luster and optical performance. Originating from Tanzania, this sapphire is notable for its natural, untreated color, with no enhancement reported, which adds to its rarity and collectible appeal.

From a grading perspective, this sapphire is described as slightly included, evaluated at eye level. Slightly included means there are small inclusions that can be seen with careful viewing without magnification, and they do not compromise structural integrity or overall beauty. For an educated buyer, such inclusions often signal natural formation and provenance, and they may actually contribute to the gemstone story and authenticity. The mixed brilliant cut optimizes brilliance and scintillation, masking minor inclusions by directing light across the pavilion and crown. The excellent polish further ensures that light interacts with the stone cleanly, producing crisp reflections and a lively appearance. As a corundum, sapphire rates nine on the Mohs hardness scale, offering strong resistance to scratches and making it well suited to the daily demands of an engagement ring.

Collectors and informed purchasers will value this sapphire for a combination of attributes that drive both aesthetic and intrinsic worth. Its intense yellowish green hue is less common than traditional blue sapphires, creating a distinctive and personal statement. The fact that the stone is untreated and of Tanzanian origin increases rarity and desirability among connoisseurs who prioritize natural color and ethical sourcing. The 1.64 carat weight and oval silhouette provide a versatile center stone for bespoke engagement designs, from classic solitaires to halo and three stone settings. The elongated oval shape flatters the finger, producing the impression of greater spread than a round equivalent, and the measurements translate to an elegant scale that reads confidently without overwhelming most ring settings.

As an engagement choice this sapphire offers both symbolism and practicality. Its durable corundum structure ensures longevity for a piece intended to be worn every day, while the unique yellowish green tone stands apart as a statement of individuality. Consider settings that celebrate the color, such as warm 18 carat yellow gold to enhance the yellow notes, or platinum and white gold to emphasize contrast and brilliance. A halo of small white diamonds can increase apparent size and brighten the overall look, while a classic four or six prong solitaire will showcase the mixed brilliant cut and intense color.
