Description

Very good specimen of champagne-colored fluorite with white calcite and a few golden chalcopyrite crystals.

The Schwanz collection provided a few specimen from this very seldom offered locality. Fluorites from the Silberberg were only found for a short time by a few collectors, who kept it a secret and didn't offer any specimen to the market. Even some special black forest collectors don't know this locality.
