12.11 Ct. Cabochon Tanzanite from Tanzania

One translucent violet tanzanite, weighing 12.11 carats, is presented in a round shape with cabochon cut, measuring 11.58 x 11.40 x 9.49 mm. The stone displays an intense violet color intensity with strong saturation and appealing translucency, producing a rich visual presence under a range of lighting conditions. Clarity is graded included, evaluated at eye level, and the gem shows natural internal characteristics that are observable without magnification, including fine needle like inclusions, faint growth zoning, and one small surface reaching feature near the dome that is consistent with natural formation. The cabochon profile has been well executed, with an excellent polish that yields a smooth reflective surface and allows the violet tone to read consistently across the dome. The material has undergone routine heat treatment to enhance and stabilize the blue violet color, and the origin is documented as Tanzania, a recognized source for tanzanite material.

This 12.11 carat cabochon is well suited to designs that emphasize a protective setting and visible dome, including pendants, brooches, and statement rings where the gem can be appreciated at eye level and the included characteristics become part of the aesthetic. For durability, secure bezel settings or guarded prongs are recommended to minimize exposure to knocks and to protect the surface from abrasion. Tanzanite has moderate hardness and directional cleavage, therefore cleaning with warm soapy water and a soft brush is advised, and exposure to ultrasonic cleaning, harsh chemicals, and sudden temperature changes should be avoided. Full disclosure of carat weight, exact measurements, cut style, clarity evaluation, treatment, and origin is provided by The Natural Gemstone Company to assist in appraisal and selection. The combination of intense violet color, cabochon dome, and natural included character makes this tanzanite a distinctive specimen that offers strong visual appeal when set thoughtfully and cared for according to standard gemstone handling practices.
