Gudmunds gruve (Citrinbruddet), Landsverk, Evje og Hornnes, Agder, Norge
A small pegmatite quarry presumably opened around 1955, when Gudmund Olsen (father of Reidar Kjetså) produced a small quantity of feldspar. Associated with the feldspar was a huge quantity of quartz crystals. Abundant quartz crystals could be found on the path to the quarry as late as 1974 (Reidar Kjetså information).
The quarry is also called Citrinbruddet (Citrin Quarry), but that name is misleading, as most if not all of the quartz crystals are covered by a thin film of iron oxides, giving them a yellow-brown-red colour (Ronald Werner commentary 2019).
In the 1990's Ivar Gautestad blasted a few times here, in order to take out more quartz crystals.
In the period 2004-7 a new cavity was opened, yielding a fair amount of quartz crystals. .
The quarry is situated 350 m SSW of the shop near the Landsverk 1 quarry.
