Must Buy for Rock Lovers

I really wasn't expecting such large pieces! I'm very happy with the purchase. I've gathered a small collection of rocks/crystals over the years, and often when you buy from Amazon you fear getting games, but there's no doubt these are the real deal!

My only wish is that they came with a list of what specimen they could be, and a short description of them, or at least a recommended resource to figure it out. A real rock hound wont need that, but an aspiring one like me needs a little nudge. 

Otherwise perfect. I recommend!
