Obsidian is a strongly protective stone, it forms a shield against negativity. It blocks psychic attack and absorbs negative energies from the environment. Obsidian draws out mental stress and tension. It stimulates growth on all levels, urging exploration of the unknown and opening new horizons. Obsidian dissolves emotional blockages and and grounds your energy. When combined with Clear Quartz as is in these double terminated pieces, the crystal brings clarity to the mind and clears confusion.
