Serpentine

Serpentine is a group of minerals that are typically green, yellow, or brown, known for their smooth, waxy, or slightly greasy appearance. They form through the alteration of magnesium-rich rocks and are often used as ornamental stones or carving materials. The name "serpentine" reflects its serpent-like, winding patterns in some specimens. Chemically, they are complex silicate minerals, and their texture can range from compact to fibrous. Serpentine occurs in various geological settings worldwide and is valued both for its aesthetic qualities and its role in understanding geological processes.
