Tourmaline is a virtually unique colour miracle : this gemstone exists in red and green, blue and yellow, and even in colourless and black respectively. Often there are even two or more colours displayed in one and the same Tourmaline crystal. Highly coveted rarities are colour changing Tourmalines or chattoyant ones. However, the classical colour for Tourmaline is green. And if you ask gemstone dealers for Tourmaline, the green variety will almost inevitably be the first one to come to their minds.
Tourmaline is loved as a perfect jewellery stone by many women, but it has also come to be preferred nowadays by quite a few men.
