Mineral wealth of Písek region |
The exposition Mineral wealth of Písek region provides visitors with a detailed picture of inanimate nature of the region. The exposition is divided according to individual geological units and types of occurrences of minerals that are classified chronologically by their age. A special place in the exposition belongs to the mineral písekit that was found in Písek feldspar quarries as on the only place in the world. A separate show case is dedicated to another rarity of Písek pegmatites, rare precious stone types of beryl. These types of beryl in forms of heliodor and aquamarine were found in feldspar quarries from time to time as quite big and very good quality pieces and are the most valuable precious stones that were ever found in Bohemia.
