Serpentine is a the name given to a group of metamorphic minerals in shades of green. Serpentine has been used both as an architectural building material and also cut for ornamental uses for centuries. The main characteristics of serpentine are its green color, patterned appearance, and slippery, almost greasy feel. These properties remind the observer of a snake, from which the name "serpentine" was derived.
Serpentine is rather soft compared to most jewelry gemstones. It is susceptible to acid, so harsh chemicals and cleaners should be avoided. Use only a soft cloth and warm water to clean serpentine gemstones. Store serpentine jewelry in a box to prevent scratches.
