Definitely looks interesting. Don't really see any crystal faces though so hard to tell. Can you please provide the following additional info:

1) What is the locality this was found in? 2) Did you find any others similar to it? 3) Can you test the hardness? 4) Can you post a few more pictures?

Thanks
