         | heat and pressure._

         | Try buying some zircon nearby. Or perhaps there are small
         | fragments in the river nearby (ask if it's legal to pick them).

           | their provenance.

         | I learned some time ago that there are crystal wholesalers.
         | Someone I know got a crystal from here that had a drop of water
         | contained in the center. It was pretty awesome. They are called
         | enhydro crystals.

       | "Silmarils"...
