Kongsberg is a classic European mining district, renowned for its Silver specimens. Mining at Kongsberg began in the 17th century and continued for several centuries, making it one of Europe’s most important silver-producing localities.

Geologically, the mineralization consists of low- to moderate-temperature hydrothermal veins hosted in Precambrian metamorphic rocks and gneisses of the Scandinavian basement. Silver occurs associated with silver sulfides and sulfosalts within fracture systems, forming the characteristic wire-like and branching habits for which the locality is famous.

EG12P0: Telluronevskite is an extremely rare selenide of Bismuth and Tellurium and its type locality is the Vihorlat Mountains in the Slovak Republic. This specimen comes from there, not so aesthetic but extremely rich (for the species).
We will send to the customer a copy of the analysis where Telluronevskite also appears intergrown with the still more rare species Ingodite and the 'common' mineral Nevskite. The description of Telluronevskite was published in 2001.
