information on lapis
     The full correct name for lapis is lapis lazuli. It is a metamorphic material that is
created when an impure limestone is baked by contact with a granite intrusion. Surprisingly,
lapis is a combination of four minerals: hauynite, sodalite, noselite, and lazurite with minor
inclusions of pyrite (yellow metallic specks) and calcite (white). The most desirable lapis has
a dark, rich blue color with minimal pyrite.  Most lapis comes from the Badakshan district in
northeastern Afghanistan.
