Marbles are limestones, definitely softer than granites. Due to this feature, marbles are easy to work and carve. They appear in a wide range of colours. They are frequently used for fireplaces, not very intensely used surfaces, walls, window sills. Marble slabs are usually 2cm and 3cm thick, but sometimes thick slabs of 12cm, 15cm and more appear. Thicker marble templates are used to make carvings.
