"Jewelry-industrial" and "industrial" materials range down a scale from lazurite, jadeite and nephrite at the top, through charoite, rhodonite, jasper and petrified wood, to items like "aventurine quartzite," "ophicalcite (serpentine/calcite)" and "agalmatolite (pyrophyllite/talc)," although, perhaps mercifully, the last three which merit separate chapters in the parade of chapters to follow are malachite, chalcedony and rhodonite.
