Tanzanite is, mineralogically, a blue zoisite. The name Tanzanite is a commercial name given by Tiffany, a famous American jeweler. Tanzanite is a pleochroic stone, meaning its color changes depending on the viewing angle and lighting conditions. It has the characteristic of appearing a vivid blue in natural daylight and appearing purplish under night light or artificial light. The main coloring factor is the trace amount of vanadium, and those with darker colors contain a trace amount of chromium oxide. Tanzanite changes color, appearing blue, green, purple, and yellow depending on the viewing angle. Most are heat-treated. Product number: BG6134-65
