The most appreciated color for this gemstone variety is a blue with some tint of purplish that is really attractive, especially in larger sizes with strong saturation. This gemstone is relatively young, but it is becoming popular and appreciated from customers and jewelers, with its pleochroism, high hardness and often eye clean clarity can be a cheaper substitute of sapphire.
Origin of Tanzanite is Tanzania where it was first discovered. Finest quality over 5 carats with eye clean clarity and good color saturation can raise high price.
