Here is a matrix with a centered cavity filled with a colorless, transparent, gemmy and doubly terminated Herkimer diamond. But what makes this a particularly impressive and rare Herkimer is that it is twinned! Great contrast and striking piece – literally a diamond in the rough! (A Herkimer Diamond is a variety of Quartz crystal found in the vicinity of Herkimer, New York.)

Location: Herkimer County, New York, USA

Size: 7 x 8.2 x 4.8 cm
