12.65 Ct. Star Ruby from Mozambique

One beautiful semi translucent GIA certified Purple Red 12.65 carat oval shape purplish red star ruby awaits collectors and connoisseurs at The Natural Ruby Company, the stone presented with dimensions of 13.26 x 11.54 x 8.38 mm. The gem is cut as a double cabochon to maximize asterism and visual balance, and it exhibits a clarity grade of very slightly included evaluated at eye level, vivid color intensity, and an excellent polish. Enhancement heat treated is disclosed, and the origin of this star ruby is Mozambique, certified by GIA, lab color classification Purple Red. This combination of substantial carat weight and precise oval proportions makes the stone ideal for a bold solitaire or a classic pendant setting, the generous size allowing the six ray star to sit proudly on the finger or chest without being crowded by metal.

The asterism of this star ruby is a defining feature, the six ray star appearing sharp and centered when a single overhead light source is used, the effect created by oriented needle like rutile silk that intersects within the crystal structure. Because the gem is semi translucent and vividly saturated in a purplish red hue, the star seems to float across the surface, strong against the rich body color, the double cabochon cut enhancing symmetry and star responsiveness from multiple viewing angles. At eye level the inclusions are very slight, the stone presenting as clean to the unaided eye while retaining the natural silk responsible for the star, this balance of clarity and asterism is what collectors prize. The excellent polish ensures crisp light return and a pleasing tactile finish, the vivid color intensity and the Mozambican origin confirmed on the GIA report adding provenance and market confidence.

For wear and care, I recommend a protective setting such as a low bezel that frames the stone and minimizes exposure to knocks while still allowing light to activate the star, prong settings with a secure head work well for rings where daily wear is planned, and pendants or brooches allow the gem to be enjoyed with less risk of impact. Cleaning is best done with warm soapy water and a soft brush, avoiding harsh chemical cleaners and strong ultrasonic or steam cleaning if the stone has surface reaching inclusions, the disclosed heat treatment is stable but gentle maintenance will preserve polish and asterism over time. At The Natural Ruby Company we provide the GIA certificate with the purchase, we can supply additional high resolution images and a short video showing the star under directional light, and we offer custom mounting and independent appraisal services to support insurance and resale.
