Gottfried Wilhelm Leibniz once said that as we can't find two pieces of leaves are the same in the world. Everyone of us is different from each other. So does the healing stone. Each of the stone is unique.

Obsidian is an earth-stone, activating the root chakra and grounding you in your connection to the Earth. It clears the aura of negative energy, and can also be used for scrying. Obsidian is a volcanic glass created when lava erupts from a volcano with certain conditions. Pure obsidian is dark, but impurities can result in dark green, brown, black, and gray coloring. Other impurities result in stones known as snowflake obsidian, golden obsidian and rainbow obsidian.
