2.83 Ct.Tw.Total Carat Weight Ruby Pair from Burma (Myanmar)

This matched pair of Burmese rubies combines precise lapidary work with classic provenance and measured optical performance. Individually the stones weigh 1.48 carats and 1.35 carats, with diameters of 7.11 by 7.01 by 3.57 millimeters for the larger stone and 6.96 by 6.88 by 3.45 millimeters for the smaller, both cut to a round outline. The faceting style is mixed brilliant, employing a brilliant crown geometry with a pavilion optimized for light return through a mix of brilliant and step facets. Clarity is graded slightly included at eye level, indicating the presence of natural internal features that do not materially detract from transparency or light performance when set. Color is described as vivid in intensity, presenting a saturated red that is characteristic of high-quality Burmese material, and the surfaces exhibit an excellent polish across all facets. Enhancement by controlled heat treatment is disclosed, a stable and trade-accepted process used to improve tone and diminish certain inclusions without the introduction of foreign filling substances. Origin is Burma, also known as Myanmar, a source renowned for fine ruby material, and provenance is an integral part of the value equation for these stones.

From a technical perspective the cutting and proportions of these stones have been calibrated to balance color saturation with brilliance, which is essential in rubies where excessive depth can mute color and excessive shallowness can cause windowing. The measured pavilion depths of 3.57 millimeters and 3.45 millimeters correspond to depth-to-diameter ratios just above 49 percent for each stone, a proportion range that favors strong color saturation while retaining lively facet contrast. The mixed brilliant arrangement concentrates smaller star and kite facets on the crown to maximize scintillation, while the pavilion’s hybrid facet scheme disperses return light to preserve the stone’s vivid red without causing excessive darkening. Girdles present as consistent thin to medium thickness, which facilitates secure setting while minimizing visible metal rim at the stone profile. Polishing quality is high, producing crisp facet junctions and minimal surface disturbance, which enhances both the subjective visual appeal and objective light throughput. Slightly included clarity at eye level typically indicates fine silk-like rutile or minor crystal inclusions that act as internal fingerprints of natural origin, and in this pair they contribute to the gem’s character while remaining non-distracting in jewelry.

As a matched set these two rubies offer rare parity in color, cut, and lustre, making them especially suitable for high-quality earring pairs, a two-stone ring, or a matched pair in bespoke designs where symmetry and chromatic harmony are paramount. The near-equal diameters and consistent visual weight, with a weight ratio acceptable for matched pairs, mean the stones will read as a cohesive unit in matched settings. For mounting, prong or open-backed basket settings will maximize the interaction with light and reveal the full scope of the vivid hue, while low-profile bezel settings can be employed to protect the girdle without unduly reducing apparent size. Given the heat-treated enhancement, routine care should be standard for fine rubies, avoiding harsh thermal shocks and aggressive chemical cleaners, and preferring ultrasonic cleaning only when the mounting and any inclusions are assessed as stable. Ownership of a matched pair of natural Burmese rubies such as these represents both aesthetic and collector appeal, combining geographic pedigree with lapidary refinement.

The Natural Ruby Company offers this pair as a precisely matched set, and we stand behind the technical information and provenance provided. For the connoisseur who values measured proportions, facet symmetry, and color integrity, this pair represents a compelling acquisition opportunity, delivering both immediate visual impact and long-term desirability. We can provide additional facet images, detailed measurements, and mounting recommendations to assist with bespoke design or appraisals, and our team can advise on optimal settings to preserve and showcase the stones’ vivid color and light performance.
