This little tanzanite crystal measures 1.7 x 0.9 x 1.0 cm, but it is gem clear at the termination and could actually cut a small stone because of its nearly equant shape. From the sides, it has a nice deep purple color, while it appears blue when looked at front to back. Because it is more square in cross section than many crystals of its size, its color has better saturation. A very nice piece with no damage that weighs 3.0 grams.
