Native Arsenic - Geschieber vein, Svornost Mine, Jáchymov, Karlovy Vary District, Karlovy Vary Region, Czech Republic

This exceptional specimen of native arsenic originates from the historic Geschieber vein of the Svornost Mine in Jáchymov, one of Europe’s most famous and mineralogically important mining districts. The piece displays the classic metallic luster and steel-gray to tin-white coloration typical of elemental arsenic, often showing botryoidal, reniform, or massive textures formed through low-temperature hydrothermal processes. Jáchymov (formerly Joachimsthal) is a legendary locality in the history of mineralogy and mining, known for its complex ore veins rich in silver, uranium minerals, and rare native elements.

Specimens of native arsenic from Svornost are highly sought after by collectors of classic European localities and native element suites, particularly those with documented vein associations such as Geschieber. Due to the toxic nature of arsenic, this specimen should be handled minimally and stored in a stable display environment. It is best suited for knowledgeable and advanced collectors who understand proper handling, storage, and long-term care considerations for arsenic-bearing mineral specimens.
