Tanzanite is a relative newcomer on the gemstone scene, but it's also one of the most popular. Introduced in 1968, it was added as a December birthstone in 2002. All the world's tanzanite is mined in one small area of Tanzania. Tanzanite comes in a wide range of colors, but it's the bluish-violet stones you want to look for. Pale lavender tanzanites are very popular, but the finest stones have a predominantly blue color with flashes of violet. Tanzanites will change color slightly as you rotate them and view them from different angles, at times appearing more blue or more purple.
