Description

A old timer (19th century) from Australia: thin blades of azurite are in part pseudomorphed by malachite (and others!), some star-shaped aggregates of light blue azurite visible where the matrix was broken. Unfortunately I do not have a detailed location,  just Australia. From the Dr. Krantz stock, Australian suite.
