An old-time and showy specimen of sparkly, bubbly, botryoidal pseudomalachite richly filling two vugs on the sculptural, conical-shaped gossan matrix from a classic Russian locality - Nizhnii Tagil, Urals Region. This material was originally named tagalite in 1846, but later determined to be pseudomalacite. Accompanied by an old label, torn in two: Augustus Krantz label dating from 1850 to 1888. The collection this came out of was a museum stash dating to prior to World War I.
