This beautiful blue-purple gemstone was discovered in the late 1960s and recognized worldwide as a new gemstone. The name Tanzanite comes from the country where it was found: Tanzania. The world's only mining area for this attractive gem is in the Merelani Mountains, near Arusha. The site is barely more than 20 square kilometers in size and geologically unique. Experts believe that the likelihood of gemstone-grade tanzanites being found elsewhere again is negligible.
Tanzanite gets its characteristic blue color from traces of vanadium in the crystal structure. It is actually the purple-blue variety of the mineral zoisite. Tanzanite displays a strong pleochroism. That means the stone is purple when viewed from one direction and blue at 90 degrees rotation. Provided they are cut correctly, these two shades run together and one gets the color palette that is so characteristic of tanzanite. This is what makes this mineral so unique and what sets it apart from the other blue gemstones such as the sapphire. In addition, the strong transparency and the usually complete lack of natural inclusions are responsible for its exclusive beauty. It is common and fully accepted that the color is enhanced by heating.
The so-called fancy tanzanite is a specialty. Fancy tanzanite is tanzanite in unusual colors, such as pink, yellow, green, and orange. These gemstones are many times rarer than the blue ones and therefore highly sought after by collectors all over the world.
Tanzanite has significant potential for value creation as it is a gemstone that has gained popularity all over the world for its beauty. The demand for tanzanites is constantly growing. There is also only one source of origin and it is therefore not common. This means digging deeper and deeper to get to this coveted gem. That drives up the price of mining enormously. In addition to tanzanite, this is also an important reason for many other gemstones why they are becoming increasingly expensive.
