Black amethyst is amethyst that either has a higher concentration of iron (making it a much deeper purple), or the matrix on which the crystal has grown is darker, thus making the crystal appear black. Black amethyst has most of the same properties as amethyst. Due to the higher iron content, it is typically more grounding than purple or pink amethyst. Black amethyst can be used for protection, and clearing of negative energy. It can be used at the Earth Star, Root, Third Eye, or Crown chakras. It can be beneficial for protection when astral traveling or dreaming, as well as against psychic attack. Black amethyst can help you maintain focus during meditation, as well as being useful when processing through spiritual awakenings.
