Listing for a Single Crystal. These beautiful rough obsidian pieces are wonderful to protection work. Good for protective workings and cleansing rituals. Please remember that every crystal will be different and are selected random and some have sides that are less shiny and matte. We understand that not everyone can sage cleanse and not all crystals can be cleansed with water, so we make sure that each of our tumble stones are cleansed of energy before they are packed up and shipped to you, allowing you to work with them straight away, no need for cleansing before use (but you still can if you want to).
