This glistening beauty is a black obsidian Tower. The edges are super clean and sleek, and the stone is a really good quality item. It measures approximately 3 inches tall and is a new addition to my shop. Black Obsidian: is often associated with mystery and has a very strong ability to absorb. For this reason it is used often in feng shui, spiritual connection and protection. It is also known as a spiritual cleanser because of its ability to absorb psychic smog and help to see things more clearly.
