Native Iridium (rare) Fioravanti Coll.

Item Description

Osmiridium is a rare variety of iridium rich in osmium ( in which the individual bits are either more osmium or more iridium-rich individually). The bottom of this slender glass vial is filled with a multitude of tiny, splendent, silvery flakes. This is a little hoard of this rarity and is seldom available in any quantity. Old-time material that undoubtedly dates to Imperial Russia times, prior to World War I. Ex Giancarlo Fioravanti Collection and acquired in Rome in 1976.
