Lava Stone is a grounding stone that strengthens one's connection to Mother Earth. It gives us strength and courage, allowing us stability through times of change. It provides guidance and understanding in situations where we may need to "bounce back". A calming stone, it is very useful in dissipating anger.
Lava stones are the root chakra and crown chakra
Lava is associated with the root chakra as, like roots, it comes from deep in the ground. The earthy qualities of lava make it a stone of grounding, focus and balance, materialism and restraint. Its fiery energy is associated with passion, assertiveness and energy.
Lava stone is an incredibly powerful stone for anyone born under a fire sign in their astrology, or for anyone who needs more fire in their lives. Since lava stone is known for its grounding qualities, it is wonderful for calming the emotions.
