From the famous Tanzanite mines in Tanzania, we are able to bring you an affordable grade of Tanzanite. All of this material has been heat treated to bring out the majestic blue/purple color that has made Tanzanite one of the most popular gemstones in the world! We believe we are the only company that is able to offer this grade of Tanzanite at such a reasonable price. A very unusual material not generally found anywhere else. We have heated this material to a beautiful lavender blue then tumbled it to a polished finish. Fantastic for use in Baroque jewelry just as is, for drilling and stringing, or possibly the beginnings of an exotic gem tree.
