3.01 Ct. Ruby from Mozambique

This 3.01 carat oval ruby from Mozambique presents a combination of precise cutting and natural corundum structure that delivers exceptional optical performance. Dimensions of 8.84 x 7.42 x 5.15 mm yield an ideal table to depth ratio for an oval mixed brilliant cut, enabling strong light return and balanced scintillation across the face of the stone. The mixed brilliant execution uses a brilliant facet arrangement on the crown to maximize brilliance and fire, paired with a modified step pavilion to create controlled light channeling and contrast patterning. Clarity grade very slightly included evaluated at eye level confirms that the stone is visually transparent under normal viewing, while internal silk and pinpoint features remain fine enough to act as light scattering sites that enhance sparkle rather than obstruct it. Color reads as vivid, with saturation and tone that produce pure red transmission through multiple facet intersections, and polish is excellent, producing crisp facet junctions and mirror like surfaces that preserve angular light reflections.

The structural reasons for the ruby s unmatched sparkle are both material and cutting related. As corundum it has a high refractive index around 1.76 and modest dispersion, which combined with the mixed brilliant geometry amplifies both brilliance and the perception of fire. The crown angle and pavilion depth were balanced to favor high internal reflection, while the oval outline and symmetrical facet layout minimize windowing and create even scintillation when the gem is rotated. The absence of enhancement preserves natural lattice chemistry and light interaction, ensuring stable color and predictable light performance in settings. For the connoisseur seeking technical quality and visual dynamism, The Natural Ruby Company offers this Mozambique ruby as an example of expert lapidary control, natural provenance, and uncompromised finish. It is particularly well suited to center stone ring settings where pavilion clearance and table proportions can be optimized, providing unparallelled face up brilliance, lively facet play, and a vivid red presence that reads powerfully in both daylight and artificial illumination.
