One of the rarest and most beautiful gemstones on the planet. A gemological and geographical phenomenon. Claimed to be 1000 times rarer than Diamonds, Tanzanite is the blue variety of Zoisite, found in Tanzania, Africa. Tanzanite is extremely popular due to its trichroic nature, which means that three different colours can be seen when looking at the gem from different angles. As with many gemstones, the darker, more vivid its colour the more valuable it is; and dark blue Tanzanite is currently amongst the most desired, and therefore most expensive gemstones in the world. Hailed as the gemstone of the 20th century, it has been recommended to wear Tanzanite as an anti-depressant, due to the nurturing, emotionally supportive and cheering energies it is said to bestow.
