Lava stone literally comes from the core of the earth- fiery brimstone that bubbles to the surface and cools.
Once the stone is cool, it becomes porous and black, creating the beautiful black color so many have come to love.
Since lava is known for its grounding qualities, it’s wonderful for calming the emotions. In fact, the quality of fire springs from the ground, so in terms of healing gems, this lends itself to a calming- but intense- energy. Because it comes from raw energy, it’s considered to be a stone of rebirth and shedding unneeded layers of emotional attachment.
