A cobble is a stone whose size lies somewhere between a boulder and a pebble(not as thick as boulder and not even as small as pebble). Owing to its natural beauty, cobble is widely used for decorative purposes.
The cobbles made of sandstone are available in shades of maroon, pink,
green, yellow and gray. Cobbles are available in different sizes -
10x10x8cm, 20x10x8cm, 14x14x6cm, 14x14x8cm, 14x20x8cm. The peculiarity
of cobbles is that they are fireproof, require little maintenance and
need not be painted.
