Black Obsidian

Black Obsidian is excellent at bringing any emotional imbalance to the surface so that other stones and crystals may help to clear it away. It helps us to find the hidden factors surrounding a situation so that we may take the best course of action to address that situation. It helps us to retain our balance in times of change. Black Obsidian is also very good for helping us to let go of the past and breaking past habits that are no longer useful. It inspires creativity and promotes sincerity.
