Lava rock, created thousands of years ago from molten rock, and mined from the ground in southwestern USA, is an all natural stone that is very lightweight (1/2 the weight of other decorative stones). Lava rock is a very common decorative stone and is used as ground covers, pond liners (for its exceptional ability for pond plants to establish quickly), and is commonly used as media for bio-filters.
