2.67 Ct. Ruby from Mozambique

This cushion shape ruby weighs 2.67 carats, and measures 8.34 by 6.60 by 5.17 millimeters. The stone is transparent, with an intense pinkish red hue, and a clarity grade listed as very very slightly included, evaluated at eye level. The cutter chose a mixed brilliant faceting scheme, combining a brilliant style crown and a modified pavilion to balance maximum light return with color saturation. The mixed brilliant cut produces strong contrast scintillation and controlled flash, and the excellent polish on facet planes and junctions enhances crisp internal reflections and surface lustre. This ruby has been heat treated, a standard enhancement that stabilizes and intensifies the tone, and it originates from Mozambique. At 5.17 millimeters of depth the gemstone is well proportioned for a face up presentation that preserves both brilliance and an even color distribution, characteristics that The Natural Ruby Company selects for clients who prioritize optical performance and artisanal finishing.

When comparing reflective qualities within its category, corundum rubies are defined by a relatively high refractive index and modest dispersion, traits that produce bright, saturated flashes of red rather than prismatic fire. This Mozambique ruby, with its intense color and superior polish, delivers a lucid, lively brilliance and strong facet contrast, distinguishing it from more velvety or heavily included Burmese examples that may show softer, less defined flashes due to silk and diffusion. Compared with pink sapphires, which are also corundum and therefore similar in baseline optical behavior, this stone reads warmer and more saturated in the pink red range, yielding more pronounced red flashes under mixed lighting. Compared with spinel, which typically has a slightly lower refractive index and a different crystal symmetry, the ruby exhibits greater light return and punchier scintillation, while spinel can appear more glassy and even toned. Relative to poorly cut or heavily included rubies, this mixed brilliant cushion shows superior light performance, because its facet geometry and polish minimize light leakage and maximize directional flash. For buyers seeking a balance of color intensity, transparency, and engineered brilliance, this Mozambique cushion from The Natural Ruby Company represents a technically refined example of modern cutting and finishing applied to premium corundum.
