A SUPERB, OLD-TIME and HISTORICAL specimen from the Andrew Carnegie and Dr. Gary Hansen Collections. Highly lustrous, caramel-brown vanadinite barrels cover sculptural matrix on this outstanding piece from a MOST UNCOMMON Moroccan locality - Jebel Mahser. Andrew Carnegie was one of the wealthiest US industrialists before he died in 1919. Although he donated funds for the Carnegie Museum in Pittsburgh, he kept a private collection of some 400 specimens on a family estate in New York. Gary Hansen purchased his mineral collection from the Carnegie family in 1984, and kept a small selection for his own enjoyment in his personal collection, where this piece remained until 2004.
