Mahogany Obsidian
Black Obsidian is a naturally occurring volcanic glass. It is produced when lava cools rapidly with minimum crystal growth. Obsidian is different than most crystals due to a lack of crystals, which makes it a fairly inefficient energy conduit - hence it is a fantastic stone to stop any kind of energy dead in it's tracks. Although the most common color is black, it can also be green, light brown or rainbow (the rarest type). Other varieties include Mahogany Obsidian and snowflake obsidian.
Mahogany Obsidian occurs when the obsidian has impurities of Iron oxide and magnesium. Mahogany obsidian has a gentler energy than black obsidian. It is a great stone to aid people with bi-polar disorders as it helps to lift them through the lows and dampen the highs a little. It still has many of the grounding and protective energies of Black Obsidian without the extreme intensity of it. In energy healing it can often be used for working through pain management.
