Update: People have been telling me that it is a Bismuth crystal and that it is grown in a lab. It is very common and grows very rapid. By far the most interesting crystal growth I've ever seen. Almost alien! --Gabriel

I bought this thing at a crystal and gem store because I've never seen anything like it. What is it? Well I asked two different people there and one said that it was silicone carbide and that it was grown in a lab. Another person also said that it was silicone carbide and that it was a byproduct of some process in making micro-chips and it naturally grew that way. Well ok…never heard of it or seen anything grow like this before. I checked out the rest of the pieces they had and out of about 8 left they all were somewhat different but they all had the same geometry.
