Jet, which is also known as black amber, is not actually an amber, but rather fossilized coal. It is often used as a protection stone and is said to have very powerful protection energies to ward off evil, violence, illness, curses and psychic attacks. It is also said to protect finances. Jet is used to protect from depression and fear. Mystically, Jet is considered a stone of sympathy, healing, and psychic experiences. Jet is also an excellent calming and grounding stone, and helpful for treating epilepsy, migraines, stomach pain, colds, glandular problems, and lymphatic problems. Jet healing crystals open and balance the Root Chakra.
