12.65 Ct. Star Ruby from Mozambique

This GIA certified star ruby presents as a semi translucent purplish red oval, weighing 12.65 carats, with dimensions 13.26 by 11.54 by 8.38 millimeters. The stone is classified by laboratory color as Purple Red, and it displays vivid color intensity combined with an excellent polish. The gem has been heat treated, an established enhancement that improves color and clarity while retaining natural asterism, and its reported origin is Mozambique. The cut is a double cabochon, executed to emphasize the internal silk and the resulting star, and the overall appearance is of a well finished, high quality cabochon that balances color saturation and light transmission.

Optical and clarity characteristics are important for star rubies, and this specimen is described with a clarity grade of very slightly included, evaluated at eye level. The inclusions are fine and oriented so that they reinforce the asterism rather than detract from it, yielding a distinct, well centered star that responds strongly to directional lighting. The double cabochon profile is tailored to center the star and to present smooth, symmetrical domes that produce a crisp, mobile asterism across viewing angles. Under direct lamp illumination the star is pronounced and stable, and under more diffuse lighting the stone reads as a richly colored purplish red oval with even saturation and attractive translucency. The excellent polish enhances surface luster and minimizes distractive reflections, allowing the internal star and body color to remain the focal elements.

From a practical perspective the gem is well suited to secure settings that protect the domed surface while allowing the star to be viewed from above, for example bezel and half bezel settings with a protective gallery, or custom settings that maintain clearance for the dome. Given the semi translucent nature and the importance of light direction for asterism, consideration of display orientation and the relationship between mounting and light source will influence the perceived intensity of the star. Routine care should favor gentle cleaning with mild soap and water, soft brushes, and a warm rinse, avoiding aggressive ultrasonic cleaners when the presence of oriented silk might create vulnerability at stress points. The GIA report accompanies the stone for independent verification of weight, dimensions, color classification, clarity observation, and enhancement status, and The Natural Ruby Company can provide the certificate copy and condition notes upon request.

Overall this purplish red star ruby combines a substantial carat weight, a vivid saturated body color, and a well executed double cabochon that emphasizes a clear, centered asterism, all verified by GIA and sourced from Mozambique. The balance of semi translucency and vivid color makes the stone appropriate for collectors and designers seeking a striking, yet natural appearing star ruby. Documentation from the laboratory is available to support the gemological attributes described, and The Natural Ruby Company stands ready to provide further technical information, detailed photographs, or consultation on suitable settings and mounting options.
