Description

Ore specimen consisting of massive cuprite and some well-defined cuprite crystals in the vugs, accompanied by acicular malachite.

Comes with beautiful old label dated 19th century. The label means: "Kolywan - Dichtes Rothkupfererz" (an old german synonym for cuprite).

In the 19th century, the northern edge of the Altai mountains and its whole northern foreland - big parts of modern Altai region and Nowosibirsk oblast' - was named Kolywan oblast'. This was derived from Gornaja Kolywan („Mountain-Kolywan“), the designation of the Smeinogorsk mining area and todays Kolyvan village in the Altai region.

An interesting historic russian sample, hard to come by.
