From a historical perspective, Demantoid is clearly the most important variety of the Andradite species. Demantoids from the Ural mountains of Russia were discovered in 1868. Possessing an unusual green color and a dispersion even greater than diamond, demantoid quickly became a treasured and expensive gemstone and was used by the famous Russian jeweler Faberge to create jewelry.
