BIRTHSTONE: December BACK TO ALL GEMS
tanzanite
overview
To date, tanzanite may be the most exotic of the colored gemstones. They have only been found around Mount Kilimanjaro. They were only relatively recently discovered back in 1967. The crystalline structure of tanzanite allows the gemstone to appear blue, violet, or a blue-violet depending on the angle at which it is viewed. This means that a gem smith can decide which color will dominate the finished product. All they have to do is orient and cut the stone at the proper angle to achieve their desired color. Since their discovery, tanzanite has rapidly gained in popularity.
