3.01 Ct. Ruby from Mozambique

This 3.01 carat oval ruby from The Natural Ruby Company is presented with precise proportions and gemological documentation, carrying a C. Dunaigre certificate that confirms origin, enhancement, and observed properties. The stone measures 10.19 x 7.19 x 4.65 millimeters, yielding an average depth of approximately 53.5 percent relative to the mean diameter, a proportion that balances face up spread with depth driven color saturation. The shape is a classic oval, optimized for a mixed brilliant style, with a faceting scheme that combines a full brilliant crown and a carefully executed pavilion geometry to enhance return of light and maintain strong color saturation. The cut was executed to prioritize light performance and color, resulting in lively scintillation across the table and controlled flash from the main facets without losing the deep purplish red tone that characterizes fine ruby material.

Color is a central attribute of this gem, graded vivid purplish red with high intensity, and the stone is remarkably transparent for its color grade. The vivid intensity indicates a strong concentration of the chromium chromophore, with trace iron content providing the slight purplish bias that improves perceived richness under both daylight and incandescent conditions. At normal viewing distance the clarity reads as eye clean, with no inclusions visible to the unaided eye, which is particularly desirable in colored stones where clarity and color must be balanced. The surface finish is described as excellent polish, with facet junctions that present sharp edges and minimal polish lines, a detail that preserves both brilliance and clean facet reflections. The gem has been heat treated, a long established and stable enhancement in ruby trade practices, applied to improve internal clarity and to optimize hue and tone without detracting from the natural origin, which in this case is Mozambique.

From a gemological and setting perspective the mixed brilliant faceting is versatile and practical. The brilliant crown provides a lively crown sparkle that suits open prong settings intended to maximize light entry, while the pavilion construction provides controlled depth of color that reads strongly in both bezel and closed back settings. Recommendation for jewelry design includes a four or six prong solitaire ring that allows table exposure for brightness, a halo mounting to amplify perceived size and contrast for formal occasions, or a low profile bezel for everyday wear where protection and durability are required. Given ruby hardness of nine on the Mohs scale and the durable crystal structure of Mozambican material, this stone is well suited for rings, pendants, and bespoke pieces intended for frequent wear, while maintaining the elegance necessary for evening and formal settings.

The combination of technical quality and aesthetic appeal makes this ruby an exceptional candidate for collectors and designers who demand performance and provenance. The exacting dimensions and cut proportions mean predictable behavior under faceted settings and straightforward planning for lapidary remount or custom mounting. The C. Dunaigre certification accompanies the gem, confirming the Mozambique origin and the applied heat treatment, and offering the assurance expected in high end colored stone transactions. For clients seeking a vivid purplish red with eye clean clarity and excellent polish, presented in an oval that maximizes both face up color and optical performance, The Natural Ruby Company offers this 3.01 carat ruby as a piece that transitions seamlessly from casual daytime elegance to formal evening statement, delivering technical excellence and enduring beauty.
