#49658

Availability: Sold

Locality: Brushy Creek mine, Reynolds Co., Missouri, United States
Formula: CaCO₃
Size: SmCabinet 7x5x5cm

This is a fine mineral of perfection, with no flaws or damage whatsoever. The Calcite crystal is a doubly terminated scalenohedral crystal to 7.5cm and is perfect. The crystal sits perfectly on limestome matrix with Dolomite, Chalcopyrite and Galena. The Calcite itself has included Dickite giving it a "foggy" appearance. At one end the crystal is snow white from the Dickite totally intruding the crystal. It is a specimen out of the Martin Jensen collection of who had personally collected it in January of 1998 and recorded the exact locality as seen on his personal label (prov. tab). PS- it sits perfect. It shows much better in person.

Treasure Falls has more to offer besides Calcite. But this Calcite I thought was fun since it is double refrectory as seen by the doubled Hampson name.
