RM938   Silver with calcite

Kongsberg mines, Kongsberg, Buskerud fylke, Norway

A very interesting specimen of silver from Kongsberg, a historical European locality. The Bally-Prior Museum, formed by Eduard Bally (1847-1926) in Schönenwerd (Switzerland), contained objects primarily from the fields of mineralogy and meteoritics, but also from zoology, anthropology, paleontology, archeology, and history. The mineralogical collection originally consisted of 5000 specimens from Switzerland and from worldwide localities. The paleontological and archeological collections consisted of over 5.000 objects. The mineral collection grew to over 10,000 specimens. The Bally-Prior Museum was closed due a lack of financing and its collections were sold off at auction in 2003. A portion of the collection is preserved today in the Cantonal Museum of Geology in Lausanne.


Size: 2.0 x 1.5 x 0.8 cm.

Ex. Bally Museum / Ex. Thomas Rabber coll.

RM1880   Fluorite

Greenlaws Mine, Daddry Shield, Weardale, Co. Durham, England, United Kingdom

The Greenlaws mine is located in Weardale, in the northern Pennines of England, south of the small town of Daddry Shield. Around we find famous mines such as Rogerly, Boltsburn or Heights... This Greenlaws mine was worked for the galena between 1840 and 1901, being one of the most important lead mines in the area. In 2009 a group of collectors started the "Greenlaws mining project". After almost 5 years digging out the vertical shaft over 80 meters (270 ft) appeared the first specimens of fluorite, ending 2013.
This specimens we propose has been extracted from vugs found in a new connecting tunnel at 270 ft, between main shaft to a second contiguous adit. Good brilliance, transparence, with geometric color zoning that varies between purple to blue according to the incident light. With defined faces and edges and these characteristic whitish internal structures. Extremely fluorescent.
