Tanzanite

Designer jewelry with natural Tanzanite, the blue and violet variety of the mineral zoisite. This rare gem possesses a remarkably strong trichroic effect, causing its crystals to shift between shades of blue, violet, and burgundy based on the lighting. Formed approximately 600 million years ago, Tanzanite was discovered just recently, leaving us in awe of the other unearthed secrets of our planet.
