Black Obsidian Crystal Skull

Description

The Obsidian is a black-colored rock that is made from the magma which is erupted from the volcano. For this reason, it is also known as intrusive rock. The Obsidian crystal is actually an igneous rock that is formed when the molten materials coming out of the volcano cool down. Hence, the appearance of the Obsidian crystal is jet-black (dark black) in color. This crystal even contains hematite, also called iron oxide, and it contains brown and red varieties. Also, it contains tiny bubbles of gas which can have a golden shimmery effect on the Obsidian crystal.
