Tanzanite comes from the mineral zoisite. It is named so after being discovered in Tanzania and was made famous by Tiffany and Co. The blue colour is due to traces of vanadium within the zoisite. It is a trichroic gemstone meaning it changes colour meaning that it shows 3 different colours in 3 different directions.
Tanzanite as the name suggests is found exclusively in Tanzania. The Merelani hills of Northern Tanzania are known for this prized discovery of the 20th century.
Tanzanite has a hardness of 6 to 7 on the Mohs scale of hardness. This means that it can be worn in everyday jewellery but with slight caution to avoid coming in contact with harder materials.
