2.81 Ct. Star Ruby from Mozambique

I am presenting a premium Mozambique red star ruby offered by The Natural Ruby Company, a translucent cabochon weighing 2.81 carats, with precise dimensions of 9.43 by 6.68 by 3.86 millimeters, oval in outline. The cabochon cut has been executed to emphasize asterism, with the dome profile and pavilion thickness balanced to produce a sharp six ray star when illuminated. The gem exhibits vivid color intensity, a saturated pigeon blood leaning red that remains consistent across the crown and girdle planes, and an excellent polish that enhances light transmission and star contrast. No enhancement has been applied, the stone is in its natural state, and the clarity is graded included at eye level, which is typical for high quality star rubies where oriented silk and minute mineral inclusions contribute to the asterism.

From a lapidary and gemological perspective the specimen demonstrates classic features that define fine star rubies, the oriented rutile silk network is aligned parallel to the crystallographic c axis, producing a sharp, centered six rayed star when light is directed perpendicular to the dome. The cabochon dome height has been cut to optimize internal reflection and diffusion, high enough to allow the star to form cleanly, yet restrained to maintain a pleasing oval silhouette and structural stability. The translucency is balanced, permitting sufficient light to penetrate to the rutile planes while avoiding excessive milkiness that would diffuse the star, and the polish quality across the table and flanks is uniform, free of polishing pits and visible laps, which preserves the star definition and the stone surface luster.

For design and setting considerations this star ruby is highly versatile, suitable for both casual and formal jewelry contexts. In everyday designs a low bezel set will protect the dome from impact while showcasing the centered star and robust color, the generous but not excessive dome height makes the stone wearable in rings and pendants without an unwieldy profile. For formal or high jewelry applications the stone rewards minimalist gallery work and open backed settings that allow light to pass through the pavilion, intensifying the asterism under controlled illumination. The oval format at 9.43 by 6.68 millimeters responds well to classic three stone, halo, or solitaire compositions, and the 2.81 carat weight places it in a range that balances presence with practicality for most bespoke designs.

As your gemstone specialist I emphasize provenance and treatment history, provenance from Mozambique is notable for producing some of the most saturated natural red star rubies on the market, and the absence of heat or dye treatments ensures the material properties are unaltered and stable. The included clarity grade reflects the presence of silk and mineral inclusions which in this case are constructive rather than detracting, they create and center the star phenomenon and authenticate the natural origin. I recommend professional cleaning with warm soapy water and a soft brush, avoiding ultrasonic cleaning or steam due to the inclusion network, and routine inspection of any mounting to ensure secure bezel or prong settings. If you would like, The Natural Ruby Company can provide high resolution photographs under directional lighting, a detailed inclusion map, and custom setting options tailored to highlight the star, including recommended metal pairings and mounting profiles that preserve the stone geometry and maximize aesthetic impact.
