0.64 Ct. Pinkish Red Ruby from Mozambique

This transparent 0.64 carat cushion shape ruby measures 4.99 x 4.24 x 2.93 mm, and it has a mixed brilliant cut that combines the scintillation of a brilliant facet arrangement with the color retention of a step style pavilion. The gem displays a vivid color intensity, and it is unenhanced, which is increasingly rare and highly valued in the trade. Clarity is graded as slightly included when evaluated at eye level, meaning that a trained observer may notice small natural inclusions without the need for magnification, but these do not compromise the stone's overall beauty or structural integrity. The excellent polish amplifies light return, and the cushion outline provides a harmonious balance between surface area and depth, allowing the vivid pinkish red hue to sit richly under various lighting conditions. Origin is Mozambique, a source that has produced some of the most sought after rubies in recent years, known for saturated tones and good crystal quality, and The Natural Ruby Company provides provenance and transparent grading information to support the stone's value.

When comparing reflective qualities, corundum rubies such as this stone exhibit a high refractive index and a strong adamantine to vitreous luster, which yields lively brilliance and good contrast between bright facets and darker color zones. Compared with spinel, which is often admired for its clean transparency and even coloration, this ruby will generally produce stronger facet brightness because corundum has a higher refractive index. Compared with garnet varieties that carry deeper, sometimes earthier red tones, the Mozambique ruby tends to offer more lively reflection and a more vivid, saturated appearance. Compared with tourmaline, which has lower refractive index and therefore less intense sparkle, this ruby returns light with greater intensity and more distinct facet flashes. It is important to note that corundum has modest dispersion, so the type of fire seen in diamonds will be less pronounced, but the mixed brilliant cut and excellent polish on this cushion ruby maximize scintillation and color saturation, producing an optical performance that educated buyers recognize as a sign of true quality. The Natural Ruby Company stands behind this gem as an untreated, well cut example from Mozambique, appealing to collectors and connoisseurs who prioritize natural origin, clarity assessed at eye level, and exceptional color fidelity.
