Sandstone is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains. Most sandstone is composed of quartz and/or feldspar because these are the most common minerals in the Earth's crust. Like sand, sandstone may be any color, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black.
Silver is often coated on a base metal, such as copper, brass, white metal and nickel, to give it a silvery white, smooth and shiny finish. Silver plated jewelry often radiates purity and simplicity.
