My friend Crystal (yeah, funny huh) sent me this article on this breathtakingly beautiful crystal cave found near Chihuahua City,  Mexico. This place looks like heaven, but inside this deceptively tranquil cave of Selenite / Gypsum crystals it is a blistering 150 degrees Farenheit with 100% humidity!  I actually have a rather large Selenite crystal that I forgot to take a picture of when I showcased my collection. Selenite is a soft mineral with a Moh scale hardness of about three or four which means you can scratch it with a nail.
