0.88 Ct. Yellowish Green Sapphire from Madagascar

This 0.88 carat oval yellowish green sapphire presents a compact yet technically refined profile, with exact dimensions of 6.09 by 5.11 by 3.34 millimeters. The length to width ratio calculates to approximately 1.19 to 1, producing a slightly squat oval that maximizes apparent face up area for its weight. The measured depth yields an overall depth of approximately 59.6 percent calculated against the average diameter, a proportion that balances light return with color saturation and prevents the typical darkening seen in overdeep cuts. The cutter selected a mixed brilliant cut, employing a brilliant facet arrangement on the crown coupled with a more faceted pavilion plan that controls light leakage and enhances scintillation. This approach preserves weight while delivering lively crown sparkle and a controlled return of body color through the pavilion. The facet junctions are crisp and the girdle proportional, and the polish is graded excellent, which contributes to strong, even reflections and minimal surface diffusion of light. Clarity is very very slightly included as evaluated at eye level, meaning inclusions are minimal and do not impede the gem s visual performance. Importantly, this sapphire is untreated, with no enhancement, and its provenance is Madagascar, a locality known for producing sapphires with a wide range of green to teal tones.

Color and tone are central to the character of this stone, and its yellowish green hue with medium intensity occupies a precise place on the spectrum between lime and olive. Under natural daylight the stone reads as a fresh yellow green with an even distribution of color across the table, and under warmer lighting conditions the yellow component becomes subtly more pronounced while cooler light emphasizes the green, a behavior consistent with corundum s modest pleochroism in green varieties. When compared to material from other well known locales, this Madagascan example shows distinct differences that will matter to discriminating buyers. Compared with Sri Lankan yellow green sapphires, which typically exhibit a brighter, cleaner chartreuse with a slightly higher tone and a lively, almost fluorescent clarity, the present stone is a touch earthier, with a grounded olive influence that reads as sophisticated rather than overtly vivid. Versus Montana green sapphires from the United States, which frequently trend toward mint to bluish green with lighter tone and a delicate, pastel appearance, this Madagascar sapphire carries more mid range saturation and therefore stronger presence when set. Australian green sapphires are often darker and inky in tone with deep green to almost black green appearance in many examples, making them less lively under low light. By contrast this gem preserves more brightness while retaining depth, an attribute many collectors prize for versatility. The stone also differs from the rare teal and blue green material associated with certain Madagascan deposits by leaning more yellow in its hue, which gives it a unique position between the island s teal pieces and the yellow green spectrum encountered in Ceylon. Its untreated status increases its rarity relative to many commercial sapphires that undergo heat treatment to modify tone and saturation.

From a setting and usage perspective the mixed brilliant cut and the measured proportions favor designs that emphasize face up spread and maximize the balance between brilliance and color. The slightly shorter oval ratio helps the gem appear larger than a more elongated shape of similar carat weight, and the well executed pavilion faceting returns controlled flashes rather than broad pools of color, making it suitable for fine solitaire prong settings where light access is greatest. For clients who prefer more perceived size and a dressier presentation, a delicate halo of white stones will contrast and push the yellowish green toward a fresher appearance, while a bezel setting will protect the girdle and emphasize the stone s olive nuance. Because the material is untreated and graded as very very slightly included at eye level, care should be taken during setting to avoid undue pressure on inclusion sites, though the overall durability of corundum supports daily wear in conventional mounting styles. At The Natural Sapphire Company we document origin and treatment status for each gem and we can advise on setting geometry that protects the girdle while preserving the optical performance of the mixed brilliant cut. This Madagascar yellowish green sapphire is a technically considered choice for buyers who value precise cut proportions, minimal internal disturbance, and a naturally occurring medium intensity hue that sits elegantly between the bright chartreuse of Ceylon specimens and the deeper, more somber tones typical of Australian stones.
