This is a cluster of intergrown alexandrite crystals. While most of the crystals are incomplete and damaged, there are enough good faces to identify a dozens of crystals. Some of the crystals are transparent, if only slightly, and a loupe reveals bands of opaque black and transparent green alexandrite. There is a lot of color change, but I cannot say it is "good" color change, because I do not see a change to purple. Rather, it looks black with a little green in incandescent light, and quite green in sunlight.
