Smokey Herkimer Diamonds
High grade quality
Smokey Herkimer diamonds are a rare, naturally colored variety of the famous double-terminated quartz crystals found in Herkimer County, New York. Unlike typical water-clear Herkimer diamonds, these crystals feature shades ranging from light champagne to deep smoky brown or black, caused by inclusions of hydrocarbon, oil, or water trapped inside during their ~500-million-year formation.
