Obsidian 

Obsidian is regarded as the Mayan and Aztec people's sacred stone. Obsidian is a volcanic stone that forms when molten rock cools rapidly. Because volcanic rock was so abundant in the area, obsidian stone was utilized for almost everything, including tools, jewelry, and weaponry. Gold was less valuable than obsidian. It is extremely protective and helpful in determining your spiritual path. Obsidian is a potent instrument for cleansing and establishing a shield against negativity and psychic attack. It is a stone of healing, balance, and understanding. Clarity is gained, and change is supported.
