Quite a combination piece with four minerals. Central are the waterclear needle Quartz crystals to 8mm lining the center. It is crowned with thick discoidal crystals of Calcite to 2.3cm, which are color-zoned at the center. The two sulfides presnet are golden Chalcopyrite and Sphalerite crystals at the core. It sits perfect for display.
