Malachite

Malachite is a gemstone distinguished by its green stripes of many shades, similar to the blue azurite. Striking in appearance and inexpensive, it was usually tumbled smooth or cut cabochon and polished for jewelry among those that could not afford much more. Malachite was reputed to help prevent falls, and therefore was often used on devices like rings of feather falling. A typical specimen had a base value of 10 gp.
