THE GEMSTONE TANZANITE
Tanzanite is the blue to violet gem variety of the mineral Zoisite.
Recently discovered in 1967, it has become a mainstream and popular gemstone, and is used extensively in jewelry.
The main appeal of Tanzanite is its lovely colour. Its colour ranges from pure blue to purplish-blue. It is highly pleochroic, and will display different colour saturation when viewed at different angles.
Tanzanite is a very popular jewelry gemstone. It is used in bracelets, necklaces, and earrings.
It is less often used in rings due to its relatively low hardness which makes its prone to scratches.
Tanzanite gemstones are always heat treated. All purple and blue varieties of the stone are the result of heat treatment.
Natural Tanzanites have a more dull grey, greenish, or brownish colour, and heating to above 800 degrees Fahrenheit will produce the deep blue to violet colour.
The world's only source of Tanzanite is the Merelani Hills, Arusha, Tanzania.
