Azurite "balls" (Type Locality - old classic) Kay Robertson Coll.

Item Description

Classic and excellent azurite from the historic mines at Chessy, the Type Locality. The aesthetically intergrown trio of "balls" is composed of sharp, moderately lustrous, royal-blue azurite crystal nicely accented with contrasting malachite. Complete all-around and pristine, this is very fine floater specimen from this famed locale. These ancient copper mines opened in the Middle Ages and closed in 1875! Old-time very fine azurite from the Kay Robertson Collection # 11643 and acquired from Roberts Minerals in 1988 at the MSSC Show. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record). Sculptural intergrown balls of this quality are very uncommon.
