The gemstone Tanzanite, which is the blue and violet variety of mineral zoisite (Calcium aluminium hydroxyl sorosilicate) belongs to the epidote group. In 1967, Jumanne Mhero Ngoma (Tanzanian) found this gemstone in the Merelani Hills of Manyara Region in Northern Tanzania, near the city of Arusha and Mount Kilimanjaro. Tanzanite is well known because of its structural properties like strong trichroism, a shade of blue-violet appearance. The name was given after Tanzania where it was found and by the Tiffany and Co. The natural colour of Tanzanite in its natural state is little reddish brown which when exposed to heat becomes blue-violet. It is the 10th most valuable gemstone in the world. On the basis of its hardness it ranges up to 6.5 on Mohs scale.
Tanzanites are heated at the temperature of 370-390 degree Celsius after which they produce little blue-violet colour. Geologist believe that due to abundant use of the stone and as limited generation , the stone will no longer last than 25 years and because of that it has been declared as the “gemstone of generation” because the next generation will have to see it in books only. Due to its physical properties the gemstone stands along with the gemstone Sapphire which is similar and have blue colour which makes them similar to people to buy. The most preferable gemstones can be obtained under 5 carats and more than 50 carats are generally very rare to obtain.
The main origin of the Tanzanite is in Tanzania and in Merelani Hills of Manyara region and in area around 2-7 km it is found easily.
