Born in fiery brimstone that bubbles to the earths surface( and eventually cools) lava stone comes from the core of the earth. 

Lava is a rock formed from magma erupted from a volcano. 

Lava rock is a grouding stone and can help you connect with nature. Since the stone comes from raw energy, Lava stone is considered to be a stone of rebirth and shedding unneeded layers of emotional attachment.
