1.65 Ct. Ruby from Burma (Myanmar)

This transparent AGL certified Red 1.65 carat marquise ruby measures 10.64 x 5.35 x 3.58 mm, and exhibits a faceted cutting style with a mixed brilliant cut. The mixed brilliant design combines a faceted crown and pavilion geometry that is calibrated to return light efficiently for a marquise outline, while maintaining the stone proportions that preserve color saturation. The clarity is described as very slightly included evaluated at eye level, which indicates minor internal characteristics that do not interrupt face up transparency. The color presents a vivid intensity, and the polish is graded excellent, contributing to crisp facet junctions and clean light return. Enhancement is disclosed as heated with residue, and the ruby is of Burmese origin, a source historically recognized for saturated, lively red tones. This presentation and documentation are provided by The Natural Ruby Company.

When comparing brilliance and visual performance to more common gemstones, this ruby differs in character from diamond and from many white or colorless gems. Diamond typically displays higher total light return and noticeable fire due to its greater refractive index and dispersion. Corundum in ruby form has a lower refractive index, so it produces less spectral fire, yet it responds differently because the strong red saturation concentrates perceived brilliance into color rather than white flashes. Against blue sapphires, which can appear darker, this Burmese ruby stands out for its vivid red chroma and face up brightness, particularly when cut to a mixed brilliant pattern that maximizes scintillation along the marquise outline. Compared with garnets and other common red or pink stones, the combination of transparency, vivid color intensity, and excellent polish in this example yields a clearer, more luminous face up appearance. The mixed brilliant facet layout, together with the stone proportions and minimal inclusions at eye level, optimizes light return for a rich, saturated presentation. In practical terms this means a consistent, lively red that commands visual attention through color and controlled brilliance rather than through the white light dispersion typical of diamonds.
