1.79 Ct. Yellowish Green Sapphire from Madagascar

This transparent 1.79 carat oval yellowish green sapphire measures 8.47 by 6.46 by 4.03 millimeters, and it presents as a finely proportioned center stone for an engagement ring. The length to width ratio of approximately 1.31 produces a pleasing oval silhouette that visually elongates the finger without appearing overly narrow. The depth of 4.03 millimeters yields a depth percentage of approximately 47.6 percent relative to the longest dimension, a proportion that balances face up spread with internal light return. Cut as a mixed brilliant, the stone combines a brilliant facet arrangement on the crown with precision faceting on the pavilion, resulting in controlled scintillation and a flashing pattern that complements the gem s strong, intense color intensity. Clarity has been graded very slightly included when evaluated at eye level, meaning the included characteristics are minimal and do not interrupt the overall transparency or the gem s ability to transmit light, and the excellent polish enhances facet crispness and edge definition.

The mixed brilliant cut selected for this sapphire has been executed to emphasize both brilliance and color saturation, with crown angles and table proportions optimized to present the yellowish green hue evenly across the face up view. The crown s brilliant facets increase contrast and scintillation, while the pavilion s faceting directs light back through the table for lively return under varied lighting conditions. Because sapphires are corundum, the inherent hardness of nine on the Mohs scale provides durability for daily wear, and the excellent polish further reduces the likelihood of surface abrasion during routine use. The stone has been heat treated, a stable and widely accepted enhancement in the trade that improves transparency and sharpens hue without compromising structural integrity, and the treatment is fully disclosed in our description.

Color is the defining characteristic of this gem, with a yellowish green hue that displays intense saturation and a medium to medium deep tone, producing a vivid olive green presence that is simultaneously fresh and sophisticated. The interplay of yellow and green components delivers a nuanced visual impact that reads as green in cool light and takes on warmer olive notes in warm light, a quality that makes the sapphire versatile when set against different metal choices. Setting the gem in yellow gold will slightly warm and amplify the yellow component, while white gold or platinum will emphasize the greener aspect and provide a cooler, more contemporary contrast. Because the color intensity is pronounced, this sapphire retains strong visual weight even in settings that incorporate accent stones or a delicate halo, and its clarity grade ensures that color is uninterrupted by conspicuous inclusions.

As an engagement option this 1.79 carat oval yellowish green sapphire is an excellent choice for buyers seeking a distinctive alternative to traditional colorless diamonds, with the added benefits of durability, brilliance, and a personality driven color profile. The oval proportions and mixed brilliant faceting deliver flattering finger elongation and dynamic light performance that reads as lively from multiple viewing angles, while the very slightly included clarity and excellent polish provide reassurance about the gem s visual quality. Sourced from Madagascar and fully disclosed as heat treated, the stone reflects The Natural Sapphire Company s commitment to traceable sourcing and transparent description, and it is well suited to a variety of mounting styles from classic four prong solitaires to bezel settings for enhanced protection, and to halo or three stone designs for increased presence. For clients who appreciate technical precision in cut, color, and finish, this sapphire presents a balanced, carefully executed option for a unique and enduring engagement center stone.
