This vibrant gem crystal is both lovely and interesting. The color, luster, and clarity are superb, and the termination is perfect. Add to that a very interesting gently-stepped growth on all the sides, and you have a killer thumbnail. The best indication of all, perhaps, of how very good it is the fact that I took so many pics of it. Like a great book, I just couldn't put it down. These greenish zoisites are actually somewhat rarer than the now-common "tanzanite!"
