Axinite & Magnetite on Calcite (RARE combo) Robertson Coll.

Item Description

VERY RARE and rich combination material from this well-known extinct Erzgebirge mine, famous for outstanding silver, barite and native arsenic specimens. Clusters of matte finish clove-brown axinite plates and euhedral to subhedral gray magnetie crystals richly and dramatically cover both sides of massive calcite matrix. All three species are VERY RARE from here, as MINDAT has no examples in the locality photo gallery. The minerals were etched out of the enclosing calcite matrix. Magnetic, as you would expect. Ex Kay Robertson Collection # 2772 and acquired in March, 1963. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017). The piece undoubtedly predates World War II and may be much older. Rare, perhaps UNIQUE combination material from this famous mine.
