Crystal Meaning Mahogany Obsidian is Lava mixed with Volcanic Glass. Use this crystal for working out issues. The Lava stikes to the core of creation and is linked to physical bocks and poor circulation for the red energy. The Obsidian is the means to see how to unlock the energy flows and harness the red energy.
Healing uses: Most areas of energy blockage.
Obsidian Physical Properties Obsidian is a natural glass ( a silica rich volcanic rock), with glass
as its main component. It is sometimes defined as being a glassy
volcanic rock, with less than 1 per cent water content in its
structure. It is formed from volcanic lava that cooled to quickly for
significant crystallisation to occur. Hence it is amorphous, with no
cleavage; fracture is conchoidal. Obsidian is usually black, but brown,
grey and more rarely red, blue and green material is found. Group
