Rock/Mineral Info:
Gold sheen obsidian is a variety of obsidian known for its golden flash when held at certain angles in the light. This flash is caused by tiny inclusions of magnetite within the stone. Obsidian is not technically a crystal, but a volcanic glass that forms when lava cools rapidly. It is found all over the world in any region with substantial volcanic activity.
