Tanzanite is a blue variety of the gemstone zoisite. It consists of calcium aluminium silicate and is not particularly hard, so it should always be worn carefully and never placed in an ultrasonic bath for cleaning or brought into contact with acids. The deep blue of the tanzanite is fantastic, and runs from ultramarine blue to light violet-blue. This exclusive gemstone is cut in every imaginable shape from the classical round shape to a number of imaginative designer cuts.
A tanzanite will continue to fascinate with its unusual, captivating aura. Its deep blue with the slightly purple tinge is one of the most extravagant colors known to man. But what makes this stone so popular? Is it simply that fantastic color? No, it is also the exclusivity of its origin. The stone is particularly highly prized because it is found in only one place in the whole world. The idea of possessing something that not everyone has has always been one of the main criteria in the way we esteem special gems.
