BEHR PREMIUM 5 gal. #ST-127 Beach Beige Semi-Transparent Waterproofing Exterior Wood Stain and Sealer 507705 - The Home Depot

These Tumbled Lava Stones are formed when volcanic lava encounters 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. Available in various sizes
