RIEBECKITE FOR SALE
Riebeckite is a rare, sodium-rich silicate mineral that's part of the amphibole group. It's commonly found in alkaline igneous rocks, such as syenites, trachytes, and alkaline granites. It can also be found in high-grade metamorphic schists and metamorphosed ironstones. Riebeckite is named after Emil Riebeck (1853–1885), a German explorer.
