Obsidian is an igneous rock occurring as a natural glass formed by the rapid cooling of viscous lava from volcanoes. It has a glassy lustre and is slightly harder than window glass. It is generally very dark but transparent in thin specimens. It is considered a very protective stone, shielding against negative energy. Also considered to attract wealth and prosperity!
