American Fireglass 10 Lbs Grey Tumbled Lava Stones for Fire Pit or Fireplace

These lava stones are formed when volcanic lava comes into contact with cool water from the ocean and hardens as a result. The naturally occurring lava stones are gathered up and then go through a 'tumbling' process which removes any sharp edges and gives them their uniform shape. Because they are volcanic, they can withstand extreme temperatures without crumbling or exploding. Tumbled lava stones give a truly unique and stylish look to any gas fireplace which is a refreshing change from the usual fire wood. They may be used exclusively, or as a base for other fireplace ornaments, such as fire glass or lite stones. The best part is they require no maintenance at all!
