|Tanzanite is found in only one spot on the planet, the Manyara Region in Northern Tanzania near the city of Arusha and Mount Kilimanjaro. Found in 1967, the stone was initially cheap and was used as a substitute for more expensive sapphire. Over time, as the deposit was depleted, trade interest in Tanzanite grew. The stone is noted for its remarkably strong trichroism, appearing alternately sapphire blue, violet and burgundy depending on crystal orientation.|
Today tanzanite is a very popular gemstone with an ever increasing price.
