1.12 Ct. Ruby from Mozambique

This C.Dunaigre certified Vivid Red ruby from Mozambique, offered by The Natural Ruby Company, is a rare combination of color purity, clean clarity, and expert cutting. Weighing 1.12 carats and fashioned into a classic cushion shape with precise dimensions of 6.48 x 6.42 x 3.30 mm, this transparent gem presents a vibrant, lively red that reads immediately to the eye. The stone is faceted with a mixed brilliant cutting style and an excellent polish, and it has been heat treated to enhance stability and color saturation. At eye level the clarity is graded as eye clean, which means the light entering this ruby is free to travel and return without visible obstruction. The C.Dunaigre certification adds an independent layer of assurance to the intrinsic qualities of the gem, confirming its origin and treatment, and strengthening its appeal compared with many uncertified stones on the market.

The mixed brilliant cut and cushion outline work together to maximize the ruby’s optical performance, creating a dynamic play of brilliance, scintillation, and color depth that elevates the stone above typical market examples. The cushion shape softens the silhouette while maintaining a generous table that presents the vivid red face up with immediacy. The mixed brilliant approach uses a brilliant style arrangement on the crown to produce lively, directional flashes, while the pavilion facet geometry is tailored to return light efficiently for a rich, saturated appearance. With a depth of 3.30 mm relative to the average diameter of approximately 6.45 mm, this ruby has a balanced depth of about fifty one percent of its diameter, a proportion that favors a strong face up presence and reduces the window effect that can dilute color in shallower cuts. The excellent polish finishes every facet with mirror like surfaces so that each internal reflection is clean and crisp, producing flashes of lighter and deeper red as the gem moves, rather than a muddled or dull response.

Compared with many rubies available today, this piece shows several important advantages. Too many market stones are either deeply included, poorly proportioned, or cut to emphasize weight over optical performance, resulting in stones that appear dark, lifeless, or cloudy. Others have uneven polish or excessive facet misalignment that scatters light inefficiently. This Mozambique ruby, by contrast, is both vivid in hue and eye clean, which means that the light paths created by the mixed brilliant cut are unobstructed and translate into superior brilliance and contrast. The vivid color intensity of this ruby sits in a sweet spot where saturation is strong without becoming overly dark, so the faceting can create both internal sparkle and a velvety color effect. The certification by C.Dunaigre and the transparent disclosure of heat treatment provide buyers with confidence about origin and enhancement, a transparency that many lower quality offerings do not provide. For collectors and custom jewelers who want a ruby that reads as genuinely vibrant in daily wear, this gem stands out for its balance of color, clarity, cut, and certification.

For practical use and investment, this ruby is ideally suited for a refined solitaire, a delicate halo, or a classic three stone mounting where the cushion shape and mixed brilliant cut will catch and return light without competing with surrounding elements. At 1.12 carats the stone delivers presence while remaining versatile for everyday wear, and the eye clean clarity ensures that set prongs or metalwork will not need to be modified to hide inclusions. When set in warm metals such as yellow gold or rose gold, the vivid red will resonate and appear even richer, while white metal settings will highlight the scintillation and make the red pop against a cooler backdrop. The heat treatment applied to this gem is a standard, stable enhancement that improves color and clarity without compromising structural integrity, and the C.Dunaigre certification documents that fact for resale and appraisal purposes. As representatives of The Natural Ruby Company we prioritize stones that are cut to display their best optical qualities, and this ruby exemplifies that approach, offering superior face up color, lively reflection, and trusted provenance compared with many alternatives on the market.
