0.60 Ct. Ruby from Mozambique

This 0.60 carat round, transparent ruby measures 4.97 by 4.99 by 2.87 millimeters, presenting a compact yet optimally proportioned profile. The stone is cut in a mixed brilliant style, combining a brilliant faceted crown with a precisely faceted pavilion, resulting in a configuration that maximizes both scintillation and color saturation. Clarity is graded very slightly included at eye level, indicating only minor internal characteristics that do not impede light transmission. Color is vivid, presenting a pinkish red hue typical of high quality Mozambique material, and the surface finish is described as excellent polish, reflecting expert lapidary work. Enhancement is heat treatment, applied to stabilize and intensify color while preserving the integrity of the corundum crystal lattice.

The mixed brilliant cut architecture is central to the ruby s unmatched sparkle, because the facet topology controls internal light behavior in a way that differs from standard cuts. The brilliant crown faceting captures incident light across a broad angular range, breaking it into numerous small flashes as light refracts and reflects from the crown facets. Simultaneously, the modified pavilion facets act as precision reflectors, redirecting light back through the crown with minimal leakage. The result is a balance of bright pinpoint scintillation and broad face up color, the latter enhanced by the relatively shallow crown to pavilion proportions of this specimen. Fine symmetry and consistent facet junctions ensure coherent light return, while the excellent polish minimizes scattering at facet boundaries, so the apparent brilliance and fire remain concentrated and lively under varied lighting.

Origin from Mozambique contributes to the gem s optical character, as local trace element chemistry and crystal growth conditions promote the vivid, saturated tones seen here. The stone s refractive index and birefringence typical of ruby interact with the mixed brilliant facet set to produce strong internal reflections and controlled pleochroic response, which adds depth to the perceived color from different viewing angles. At The Natural Ruby Company we emphasize precise cutting, accurate proportioning, and professional heat enhancement to present a ruby that combines material quality with lapidary excellence, suitable for precision jewelry settings where optimal light performance and stable color are required.
