1.40 Ct.Tw.Total Carat Weight Ruby Pair from Mozambique

This pair of natural rubies presents as a technically refined matched set, each stone cut in an emerald step cut to emphasize uniform color and planar facet reflections. The smaller stone weighs 0.62 carats, with dimensions 6.72 x 4.81 x 1.75 mm, and the larger stone weighs 0.78 carats, with dimensions 7.05 x 4.97 x 1.96 mm. Both stones exhibit an elongated length to width ratio of approximately 1.40 to 1.42, a proportion that reads as elegant on the finger and provides a broad table for consistent face up color. The cutting style employs broad, parallel crown and pavilion steps, with clipped corners typical of the emerald silhouette, and an excellent polish that produces crisp facet junctions and smooth facet planes. Clarity is graded as very slightly included when observed at eye level, which in practice yields eye clean appearance from standard viewing distances, while minor internal features remain useful as natural fingerprinting characteristics for long term identification and provenance.

Optical performance is governed by the step cut geometry combined with an intense pinkish red hue and uniform saturation across the broad table. The step facets reduce scintillation in favor of color depth and broad flash, making color intensity the principal visual attribute. These rubies are heat treated, a stable and commonly applied enhancement, which has been used to improve color uniformity and to reduce the visibility of fine silk and fissures without altering the gems stability. The excellent polish maximizes light return across the steps, limiting windowing and allowing the stones to appear vivid under mixed lighting. At typical mounting orientations the pair presents closely matched face up tone and saturation, which is essential for designs that rely on bilateral symmetry such as matched stud earrings, twin shoulder accents, or a pair set into a single two stone ring.

From a design and heirloom perspective these rubies are exceptionally well suited to create a unique, long lived piece. The emerald step cut lends itself to settings that protect the table and corners, such as four or six prong settings with reinforced corner prongs, or a closed bezel that preserves the pavilion while deepening apparent color. A classic plan would be a paired east west set of studs in 18 karat yellow gold to introduce warm contrast, or a matched trilogy ring design where these stones flank a central diamond or a larger ruby to produce a personalized family emblem. For a truly singular heirloom, consider a convertible mounting where the pair sits within a shared backplate allowing use as either earrings or a pendant insert, combined with milgrain bezel work and a hand engraved shank or bail for a tactile maker signature. When set on a closed back with a darkened foil or a tailored metal foil plate, the stones will present richer body color, whereas a platinum open back will emphasize purity of tone and minimize color shift under daylight.

Provenance and care are integral to heirloom quality, and these Mozambique sourced rubies come to you from The Natural Ruby Company, supplied with transparent disclosure of enhancement and origin. The Mozambique origin contributes to the characteristic warm pinkish red hue and granular crystal habit commonly seen in this deposit, and the heat treatment is stable under normal wear and standard jewelry maintenance. For long term preservation we recommend routine inspection of prongs and bezels, professional ultrasonic cleaning only when settings are confirmed secure, and periodic reflow or repolishing by a trusted lapidary if surface wear is observed. If you seek assistance in translating these technical attributes into a bespoke design that will carry across generations, The Natural Ruby Company can provide CAD visualizations, custom setting proposals that protect step cut geometry, and documentation to accompany the finished piece, ensuring the stones become a verifiable and cherished heirloom.
