4.04 Ct. Ruby from Mozambique

This exceptional 4.04 carat cushion shape ruby from Mozambique is the perfect addition to any high end gemstone collection, the size and presence of this stone immediately set it apart from the more common sub 2 carat rubies that dominate the market. Measuring 10.73 x 8.79 x 4.25 millimeters, its proportions are generous without feeling bulky, translating beautifully into a variety of classic and contemporary settings. The mixed brilliant cut gives this ruby a lively and modern faceting pattern that maximizes return of light, while the excellent polish ensures each facet meets the eye with crispness and depth. The gem is transparent, with a clarity grade of very very slightly included evaluated at eye level, meaning that it reads as eye clean to most observers, a significant advantage over many commercial rubies that can show obvious surface reaching inclusions or cloudiness when mounted. The vivid color intensity is the defining feature of this stone, offering the saturated, velvety red that collectors prize, and because it has only been heat treated, it carries the stable, accepted enhancement that preserves both aesthetic appeal and market integrity.

When compared to other rubies on the market, this Mozambique example offers an outstanding combination of size, color, and clarity that is difficult to find in a single stone. Burmese sources produce legendary pigeon blood tones, but those pieces of similar hue and size command premiums that place them in a different investment tier, and many commercial rubies from Thailand and other locales often trade off color saturation for larger size or more included material. This ruby, by contrast, maintains a vivid, evenly distributed red through the pavilion and crown, avoiding the dark zoning or overly brown modifiers that reduce visual impact in many stones. The cushion shape is currently sought after by collectors and designers because it balances the classical elegance of an antique silhouette with modern faceting philosophy, and the mixed brilliant cut enhances scintillation compared to a straight step cut, bringing a livelier play of light without sacrificing the depth of color. The excellent polish and precise facet junctions make it an ideal candidate for solitaire or halo settings where the stone must stand as the unquestioned focal point, and its measured dimensions allow a goldsmith to set it with minimal alteration, preserving weight and value.
