Because it is naturally mined; it is safe for your aquarium water and fish. It is also because of this reason that no artificial colourants are used and therefore you can rest assured that you will not have potentially harmful chemicals and contaminants seeping into your aquarium water. The colours vary from bluish to brown; dark brown and hues of blue; some are mixed while others are one colour. The choice is yours.
Use it in your custom aquarium by on the back glass with silicone to hold it in place. You can create a natural aesthetically pleasing look with this method.
