This translucent oval cabochon weighs 3.49 carats, with precise dimensions of 9.21 x 6.28 x 5.59 millimeters, presenting a purplish red bodycolor of intense saturation. The stone exhibits classical asterism, a sharp and well centered star that becomes prominent under a single point light source, produced by oriented rutile silk intersecting the dome plane. Cut as a high domed cabochon to optimize the six ray stellation and light return, the profile and symmetry were executed to balance star sharpness and overall translucency, allowing the light to penetrate the body and reveal internal color zoning without sacrificing the clarity silhouette. Clarity is graded very slightly included evaluated at eye level, with inclusions that act beneficially to form the star while remaining unobtrusive to the naked eye. The surface has an excellent polish, yielding crisp star definition and lively specular highlights across the dome. This specimen has been heat treated, a standard enhancement to improve color uniformity and clarity, and is sourced from Tanzania, a locality known for producing rubies with attractive pinkish to purplish red tones.
Compared to typical star rubies of similar provenance, this piece is rare for the combination of carat weight and hue, as larger cabochons with intense purplish red saturation and clean, well centered asterism are uncommon on the market. Many star rubies in this size range trend toward brownish overtones or heavy silk that obscures the bodycolor, whereas this example retains translucency and a vivid color intensity that reads strongly even without magnification. The cutting craftsmanship is evident in the careful alignment of silk distribution and dome geometry, precisely calibrated to maximize the stellation while maintaining an elegant oval outline suitable for fine jewelry settings. For collectors and connoisseurs seeking a rare balance of size, color, and star quality, this star ruby represents an exceptional choice, offered by The Natural Ruby Company, accompanied by our detailed description of origin, treatment, and observed grading parameters. Recommended mounting approaches include a relatively high bezel or open cabochon setting to preserve the star display and protect the polished dome, ensuring the asterism remains the focal point in any finished piece.
