Refined. It is a beautiful bracelet that fascinates with the subtle elegance of natural glass obsidian with inclusions of magnetite or hematite creating the mahogany-colored patches in it. Mahogany obsidian is a hugely protective stone, perfect for people who feel vulnerable to psychic or energy attacks, and it gives strength in times of need. It eliminates energetic blockages, relieves tension, and helps stimulate growth on all levels.
