Tanzanite is the blue and violet variety of the mineral zoisite. Tanzanite is only found in a very small mining area in Tanzania. This Tanzanite was cut in Thailand in the 1990s. The Tanzanite is a bright highly polished gemstone. It has a medium dark pastel purple blue color and faces-up very well. It is better than eye clean. This gemstone really lights up. It weighs 1.23 carats. Middle Earth Traders has embellished the polish on this TANZANITE using modern state-of-the arts techniques. Tanzanite is noted for its remarkably strong trichroism, appearing alternately blue, violet and burgundy depending on the crystal’s orientation. Tanzanite can also appear differently when viewed under alternate lighting conditions. The blues appear more evident when subjected to fluorescent light and the violet hues can be seen readily when viewed under incandescent illumination. The photos seen here were taken with LED Daylight illumination. The gemstone was given the name “tanzanite” by Tiffany & Co after Tanzania, the country in which it was discovered. In 2002, the American Gem Trade Association chose Tanzanite as a December birthstone.
