Tanzanite is the purple, violet and blue variety of the zoisite family. It has distinct pleochroism, showing either purple, blue or slate-grey depending on the angle they are viewed from.

Formed some 585 million years ago, Tanzanite is a very rare gemstone found in only one place on earth - the Mererani Hills of Northern Tanzania, near the city of Arusha and Mount Kilimanjaro. Tanzanite was named after its country of origin by Tiffany's in 1968. Tanzanite is famed for its multidimensional colours: it radiates blue, violet, burgundy, green and yellow sometimes.

Tanzanite is a rare exotic treasure celebrated by specialists as the 'gemstone of the 20th century. It is also "the most beautiful blue gemstone to be discovered in 2000 years."

Tanzanite, selected as the newer birthstone of December, is believed to be a storm of transformation that helps the wearer manifest positivity and inspiration.
