Serpentine also known as "new jade" because of its mottled and sometimes scaled appearance that resembled snakes. The gemstone itself is often used as a decorative stone for ornamental objects. Serpentine is also known as false jade, teton jade, and flower jade. It has a surprising amount of names.  Treat all serpentine gently while cleaning with a mild soap and water and wipe them down with a normal untreated cloth.
