Aluminum is a projective energy metal that will shield your own energy. It is, in a sense, an invisibility cloak that deflects energy being sent your way. In jewelry, it will always protect the wearer. The planet associated with Aluminum is Mercury and its Element is Air. Aluminum also enhances mental abilities such as intellect and telepathy. It protects during astral travel and is your best friend when working with image magic (visualization during meditation). All rocks and gemstones contain aluminosilicate minerals as does the human body.
