3.03 Ct. Ruby from Mozambique

This beautiful transparent 3.03 carat cushion shape pinkish red ruby measures 9.14 x 7.81 x 4.24 mm, and is faceted in a mixed brilliant cut to balance scintillation and color depth. It carries a clarity grade of included evaluated at eye level, indicating the presence of internal features that are visible without magnification, yet these inclusions are typical of natural corundum and often confirm a natural origin to an educated eye. The color is described as intense, a primary value driver for rubies, and the excellent polish allows strong light return and surface luster. Enhancement by heat treatment has been applied, a widely accepted and stable enhancement in the trade that can deepen the pinkish red saturation and reduce the visibility of silk and other internal features. For a discerning buyer, the most important attributes are the weight of 3.03 carats, the intense color, the transparent body, and the provenance from Mozambique, which together position this stone as a compelling natural ruby for both collectors and bespoke jewelry commissions. The mixed brilliant cut and cushion outline were chosen to maximize the apparent color while preserving weight, and the combination of intense hue and excellent polish provides visual presence that outperforms many stones of similar clarity grade.

Imagine this ruby forming millions of years ago deep within the Earth, in an aluminum rich environment subjected to prolonged heat and pressure during tectonic convergence. Trace chromium atoms became incorporated into corundum as it crystallized slowly, giving rise to the warm pinkish red tones that distinguish this gem. Over geological time frames, fluids carried elements and facilitated crystal growth, and subsequent uplift and erosion freed the corundum crystals from their host rocks, concentrating some of them in veins and deposits that would later be discovered by miners in Mozambique. Once recovered, this rough was carefully studied, heat treated to enhance its intrinsic color, and cut by skilled lapidaries to a mixed brilliant cushion that balances brilliance and color saturation. The Natural Ruby Company offers this ruby with full disclosure of its origin and treatment, and we present it as a well documented, attractive example of Mozambican corundum, suitable for the informed buyer who values natural origin, significant carat weight, and intense color.
