Black Obsidian is aligned with the root chakra, which is located at the base of your spine. The root chakra is the energy point responsible for stability and grounding. Historically, the stone was used to make arrow heads and primitive blades. This natural obsidian stone is wrapped with with silver toned wire to form "the tree of life" which represents peace and immortality. The pendant measures 2" tall by 1/2" wide and will come on a silver chain or a black leather cord in the length of your choice. Tip: If you are unsure what necklace length you need, then you should use a piece of string or ribbon to measure your necklace length. Hold the string in a loop around your neck, and pull it down until it hangs where you would want a necklace to hang and then measure the string's length using a ruler or tape measure.
