Hematite - Wikipedia

Hematite's popularity in jewelry was at its highest in Europe during the Victorian era. [citation needed] Certain types of hematite or iron oxide-rich clay, especially Armenian bole, have been used in gilding. Hematite is also used in art such as in the creation of intaglio engraved gems. Hematine is a synthetic material sold as magnetic hematite.
