  • Welcome to the Spring 2021 Gems and Gem Minerals class!   From this home page you can navigate to course information, lecture handouts, on-line lecture notes and much more.  Most announcements will henceforth be posted on the UT Canvas site for this class.
  • The spinning ball and stick model above shows the arrangement of carbon atoms in diamond.  It and other minerals are easily visualized with Xtaldraw, now downloadable as Drawxtl, a powerful (and free) graphics program that displays crystal structures.
