Obsidian is actually volcanic glass formed when molten lava cools too quickly for it to crystalize. It went through an extremely fast transformation, born from the earth out of pure fire.  It is a stone without boundaries or limitations that is an extremely powerful, but often overlooked stone.  Nothing is hidden from Obsidian.  It will mercilessly expose our flaws, weaknesses and blockages.  Obsidian points out all our destructive and disempowering conditions impelling us to grow into our highest self.  Despite the harshness of what Obsidian exposes, it will be supportive as well.  It has a strong protective shield that it puts around us blocking out negativity from every angle.  It is naturally a very grounding stone that has a cord that connects us to the deep core of the earth supporting our transformation by keeping us grounded throughout.  Obsidian will help you get to the core of your problems and purify and transform you into a better version of yourself.
