3.70 Ct. Ruby from Mozambique

This oval shaped purplish red ruby weighs 3.70 carat, and its dimensions are 11.67 x 8.20 x 4.08 mm, a proportion that yields an elegant length to width ratio of approximately 1.42, a ratio that reads as a classic oval with enough elongation to flatter a finger or pendant while maintaining strong color concentration. The cutter employed a mixed brilliant faceting scheme, combining a brilliant oriented pavilion to maximize scintillation with a crown that uses modified facet geometry to hold and saturate color. The overall depth is approximately 41 percent of the average diameter, a proportion that indicates intentional planning to balance return of light with preservation of chroma, so the stone presents lively facet sparkle without sacrificing the deep purplish red that defines its character. The table to crown relationship and the faceting symmetry have been executed to yield strong facet contrast, which is critical in a darker color intensity ruby, because properly placed brilliant pavilion facets deliver flashes of white light that animate the stone, while the crown facets control the visual distribution of hue under varied lighting.

Color is the defining attribute of this sapphire family gemstone, and this example shows a purplish red tone with dark intensity that will read as distinctly regal in most settings. The dark color intensity means that under direct light the stone retains rich saturation, while the mixed brilliant cutting allows enough return of light so that facet scintillation breaks the surface and reveals internal fire. This balance lets the wearer enjoy both color and sparkle, a duality that is often difficult to achieve in deeper tone rubies. The purplish bias provides a contemporary and romantic nuance to the classic pigeon blood concept, offering a slightly cooler red that interacts beautifully with white metal settings or warmer yellow gold tones, depending on design intent. In jewelry, this color will hold depth in overhead natural light, and come alive with pinpoint flashes under artificial sources, creating a communicative presence that reads as intentional and precious.

Clarity is graded as included at eye level, which in practical terms means there are internal characteristics visible without magnification that testify to natural growth and origin, while not compromising the structural integrity or polish. Inclusions in Mozambique rubies commonly include mineral crystals, wisps, and silk nets, features that often remain stable through standard jewelry wear when the stone is properly set, and those internal features can contribute to light diffusion, softening the overall appearance in a way that can deepen perceived color. The stone has an excellent polish, indicating that the final lapidary work removed any surface disturbances and provided crisp facet junctions that enhance brilliance and tactile quality. Enhancement by heat treatment is disclosed, a stable and well understood process in ruby production that improves clarity and deepens hue without detracting from long term stability, and is an accepted enhancement within the trade. Origin from Mozambique is notable because this region produces corundum with vibrant saturation and characteristic inclusions, and many cutters optimize facets to preserve natural color while enhancing eye appeal, which appears to be the case with this piece.

This 3.70 carat oval purplish red ruby from The Natural Ruby Company represents an exceptional candidate for a striking gift for someone special, because it combines meaningful size, elegant proportions, and a color that reads as both noble and intimate. For a set center in a three stone ring, a halo engagement, or a bespoke pendant, the mixed brilliant cutting will create lively movement, while the dark color intensity will deliver presence and gravitas that announce significance. Design recommendations include a bezel or partial bezel for daily wear, or a four or six prong setting to allow maximum light interaction for evening sparkle, and pairing with white diamonds will emphasize the cool red tones, while a rose or yellow gold bezel will warm the purplish bias and produce a vintage inspired emotional effect. When presented as a gift, the combination of measurable technical excellence, regional pedigree, and considered enhancement tells a story of thoughtful selection, and The Natural Ruby Company is prepared to provide detailed images and matching setting advice to ensure that the final presentation is as technically refined and emotionally resonant as the gem itself.
