1.41 Ct. Ruby from Tanzania

This 1.41 carat oval orangish red ruby measures 6.00 x 5.32 x 4.68 mm, it is a mixed brilliant cut with an expertly executed facet architecture, the clarity grade is slightly included evaluated at eye level, the color intensity is dark, the polish is excellent, there is no enhancement, and the origin is Tanzania. The mixed brilliant strategy in this piece unites a brilliant facet pattern optimized on one plane with controlled step or modified facets on the opposite plane, a combination calibrated to maximize light return while preserving deep color saturation. Corundum optical parameters, with a refractive index approximately 1.76 to 1.77 and birefringence around 0.008, set the physical limits of sparkle, and the cutter has leveraged those limits by orienting pavilion and crown facet angles to channel internal reflections back through the crown, producing vivid pinpoint scintillation and broad flashes of orangish red that remain stable across viewing angles.

The structural proportions are instrumental to the ruby s visual behavior, the 4.68 mm profile yields a depth percentage near 82.6 percent relative to the average table dimension, a depth that concentrates the stone s chroma and deepens the hue without collapsing light return thanks to precise facet alignment and junction polishing. The excellent polish minimizes scattering loss at facet surfaces, while tight symmetry ensures phase coherent reflections that translate microscopic dispersion and internal contrast into an intense, lively appearance. Slight inclusions noted at eye level are minimal in size and distribution, they do not create pervasive light leakage, and in some viewing orientations they act as secondary reflective surfaces that enhance dynamic scintillation rather than dull the stone. The untreated nature of this ruby, with no enhancement, combined with Tanzanian provenance, gives the color and structural performance an authentic, unaltered quality that connoisseurs value. The Natural Ruby Company presents this specimen as an example of how considered cutting geometry, accurate proportioning, and masterful finishing together yield a balance of concentrated color and a sparkle that is distinct within the market, suitable for collectors and designers who demand technical excellence as well as visual impact.
