Description

A complete floater specimen featuring quartz var rock crystal, dolomite and albite crystals all around. Minor hematite ("Eisenglimmer") is present. The double-ended quartz crystal measures 3.1 cm.
No damages, somehow difficult to photograph due to lack of contrasts.

From an extremely rare swiss locality, comes with old label dated to the 1860's. The Bristenstock tunnel is part of the Axenstrasse; the construction of this important road was done in order to connect Flüelen and Brunnen, to avoid navigating lake Lucerne. Works began in 1861 and were completed in 1865.
An important sample of the beginning age of tunnel construction in Switzerland.
