Scapolite is a complex mineral group found in metamorphic and igneous rocks. It includes various types of minerals with similar physical and chemical properties, such as wernerite, meionite, marialite, and tetraferriphlogopite. Wernerite is a calcium-rich scapolite that is often used as a gemstone or ornamental material due to its beautiful peachy-pink color. Meionite and marialite are sodium-rich scapolites that are usually colorless or pale blue. Tetraferriphlogopite is a rare scapolite variety that contains significant amounts of iron and magnesium. Other synonyms for scapolite include dipyre, amatisto, and elkapite. These terms are generally not used in scientific literature, but they may be encountered in gemstone catalogs or jewelry stores.
