These 3" polished & carved black obsidian witch hats resemble that of a witches hat. Great to place in your home as well as upon an altar or for holidays such as Samhain/Halloween. A strongly protective stone, Obsidian forms a shield against negativity, providing a grounding cord from the base chakra to the center of the earth. It absorbs negative energy from the environments and blocks psychic attack and negative spiritual influences. Obsidian brings clarity to the mind and clears confusion.
