ABOUT ORCA SANDSTONE Orsa Sandstone originates from Dalarna in central Sweden. The stone is 360 million years old and consists of silicon-bonded quartz. The sandstone is primarily used as building blocks, millstones and grinding stones due to its unusual abrasion resistance and long-lasting durability. The sand grains in the stone are so delicate that the sandstone is also used for nail files and foot files. Both types are sustainable and extremely durable.
