Shree Prakash Gems manufactures Trillion-Shaped Tanzanite Gem. Shree Prakash Gems also manufactures wide range of Tanzanite gems in different shapes. Trillion-Shaped Tanzanite Gemstone is a very special and unique gemstone. The Gem is available in trichroic colour and it shows different colours when viewed in different directions. It ranges from ultra mine to a light purplish blue colour. The hydrated calcium aluminium silicate miner achieves only hardness 6.5 to 7 on the Moh`s scale, and is thus not very resistant. Therefore it should be worn with care, never be cleaned by ultrasonic method and never come into contact with acids. Its blue colour, which shimmers in a slightly purplish blue, is magnificent indeed.
