Quartz Var. Herkimer Diamond
Large Cabinet, 22.9 x 21.1 x 12.5 cm
Ace of Diamonds Mine, near Middleville, Herkimer County, New York, USA

An incredible piece with huge crystals, complete and nearly pristine all around, forming one of the largest Herk clusters I have ever seen in 20 years, museum or otherwise. There are such thick, solid junctions that I am pretty sure we have only 1 or 2 repairs here at natural contacts, whereas normally every crystal in a cluster might have to be repaired back together. The signature piece from a collection built over about 40 years, this is a monster!
