3.17 Ct. Ruby from Mozambique

This transparent 3.17 carat cushion shape ruby measures 9.95 by 7.57 by 3.92 millimeters, and it has been skillfully faceted using a mixed brilliant cut to optimize both brilliance and color saturation. The mixed brilliant arrangement pairs a brilliant style crown with complementary pavilion facet geometry, creating a balance between scintillation and depth of tone, and the cutter has calibrated table size and pavilion angles to maximize internal light return while preserving weight. Clarity is described as very very slightly included evaluated at eye level, indicating eye clean appearance with inclusions confined to microscopic or near microscopic features that do not detract from face up performance, and the excellent polish enhances facet junction sharpness and surface luster. Color is classified as intense, with a vivid red core and a subtle purplish overtone under daylight, and the stone was heat treated to stabilize and intensify chromophore distribution, a standard, accepted enhancement that improves both hue uniformity and apparent clarity. The visual result is a ruby with lively red flashes and well controlled dark areas, offering strong contrast between flashes of lighter red and the saturated body color, qualities prized by connoisseurs who evaluate both optical performance and material integrity.

When comparing hue and tone to rubies from other classic sources, this Mozambique specimen presents a vivid, intense red that sits between the leaner, pinkish tones of Ceylon rubies and the saturated pigeon blood reference associated with classic Mogok, Burma material, offering a slightly cooler purplish overtone than many Burmese examples while maintaining comparable saturation. Against Thai and Cambodian rubies that often show a deeper brownish or brick red tone due to iron content, the Mozambique ruby displays a cleaner, more vivid red, and against Sri Lankan stones that typically run lighter and more pinkish it appears clearly richer and more saturated. In terms of size and cutting potential, Mozambique material frequently offers larger clean crystals than many traditional mines, and this 3.17 carat cushion illustrates that advantage while delivering high optical performance. The Natural Ruby Company presents this gemstone for buyers who demand technical excellence in cutting, verified clarity, and a color profile that competes with the finest sources while offering its own distinctive Mozambique character.
