This "smoke on the water" purple and blue specimen is an absolute delight. The smaller balls grading from a magenta color up towards a bright blue culminating in a larger blue orb on top! The couple of contacts on the specimen provide a window through the bright colored exterior crystallization into the more traditionally colored chalcopyrite cores. On the backside, where the color isn't quite as stupendous, you can see how the spheres have grown together. This piece has all the interesting elements that this new find provides.
