Malachite

Malachite was an ornamental stone related to azurite and often used in inexpensive jewelry.

Description
Malachite was distinguished by its green stripes of many shades. Striking in appearance and inexpensive, these ornamental stones were usually tumbled smooth or cut cabochon and polished for jewelry among those that could not afford fancier gems. A typical specimen had a base value of 10 gp.

Powers
Malachite was a spell component for some divine spells of the elemental sphere and arcane spells that dealt with cold, heat, ice, or fire. It was crushed into powder for use in magical immersions for items that promoted warmth, cold resistance, or fire resistance.

Rumors and Legends
Malachite was reputed to prevent falls and therefore was often used on devices like rings of feather falling as part of the adornment. However, this was just catering to public demand because malachite had no gravitational intervention powers.
