Fluorite and quartz cast after calcite on quartz
description: <p style="text-align: justify;">LOCALITY: Shan Cun Mine, near Yi Wu, Zhejiang (province), China</p> <p style="text-align: justify;"><br />6" across <br />This plate of crystalline quartz displays three groups of "stepped" fluorite crystals. They are transparent and their surfaces display an appealing shimmering quality.  The quartz cast after calcite is hollow and encrusted by another generation of pale-purple fluorite.  <br />  <br />This fine piece was acquired via a trade with Professor Stephen Smale during a visit to Hong Kong in January 2016. <br />  <br />Photo by Matthew Webb of Melbourne, Victoria, Australia </p>
