description: <p style="text-align: justify;">LOCALITY: Artigas, Uruguay <br /><br />This amethyst specimen is hollow inside. This specimen started its life as a group of calcite crystals.  They were then encrusted by drusy quartz.  After this encrustation, the calcite crystals dissolved to leave a cast. </p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Photo by Matthew Webb of Melbourne, Victoria, Australia </p> <p style="text-align: justify;"> </p>
