Serpentine stone – from soft to hard in many colours
Serpentine is a metamorphic natural stone of magmatic origin and around two million years old. It has a fine structure and only few cracks. The structure, hardness and colouring of the individual types of serpentine rock vary greatly: serpentine that tends to lie on the earth's surface often has a light green colouring and is relatively soft, while serpentine from deeper layers of the earth tends to be dark green to black and of greater hardness.
