Serpentine is a type of mineral that is often green in color and has a smooth, waxy texture. It is commonly used in jewelry and decorative items due to its attractive appearance. The name "serpentine" comes from its snake-like patterns and colors, resembling the skin of a serpent. This mineral is primarily composed of magnesium silicate and can form in various geological environments, including metamorphic rocks. Serpentine is also associated with the asbestos group of minerals, although not all serpentine varieties are hazardous. It is often found in regions with ultramafic rocks, such as those in California and Italy.
