Description

Sharp modified scalenohedral crystals of calcite, variety cobaltoan, of a superb fuchsia colour. Crystal development is very good, that reach 11 mm in size, and they are extremely bright. The piece represent a good example of this type of material from Kambove where the crystals are associated to lustrous carrolite microcrystals, some altered to black bornite.

Collected at the Kambove Mine by René Virlet, a Belgian colonist in Congo who travel back definitively to Belgium in 1968.
