    tetide.geo.uniroma1.it/riviste/permin/testi/V75/20.pdf jervisite is a scandium pyroxene that is intermediate in the Ca(Mg,Fe)Si2 O 6 NaScSi2 O 6 series, analogous to the aegirine augite series (Mellini et al. 1982). No structural data have been so far published but jervisite is obviously isostructural with the synthetic phase NaScSi 2O 6, which was synthesized by Ito and Frondel (1968), and whose
  • The Pyroxene Mineral Group - Geology

    geology.com/minerals/pyroxene.shtml Jadeite. Jadeite (a pyroxene) and nephrite (a member of the amphibole mineral group) are the only two minerals that can legally be called "jade" in commerce. Both of these minerals are used to produce cabochons, beads, bangles, small sculptures, and a wide variety of utility items.Jadeite is the most important gemstone in China, where it has been held in highest esteem for thousands of years.
