Silver (var: Amalgum) (90% Silver/10% Mercury) (ex David Burgess Collection)

Item Description

A very rarely seen example of the Silver variety Amalgum from the locality at Allakh-Yun' in Eastern Siberia. The iece is essentially an uncrystallize mass that chemically comes in at about 90% Ag content with about 10% Hg content. A cool specimen for any native element collector, rarities collector or somebody who likes Russian minerals. The piece comes from the worldwide collection of David Burgess (1951-2016). David was a prolific species collector from Newington, Connecticut, and the namesake for the extremely rare cobalt arsenate species Burgessite, which he discovered. Additionally, there is a label from Czech and Slovak expert and mineral dealer, Josef Vajdak plus a label from the Fersman Museum in Russia.
