Item Description

Azurite is certainly a rare secondary species from the Swiss Alps and is VERY RARE from the five localities listed by MINDAT for the well-known Binn Valley. The scuptural thumbnail sliver is richly covered on both sides with rich blue microcrystals with complimentary green malachite patches. Ex Kay Robertson Collection with no number. Her label was lost in the move. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record). A RARE Swiss classic.
