TitleSix samples of Herkimer Diamond (quartz) from Herkimer County, New York, USA
DescriptionThese quartz crystals, from Cambrian limestone in upstate New York, are all about 0.5 cm in longest dimension. Although they are quartz, not diamond, they are called “Herkimer diamonds”, in reference to the type locality where they are found and their clear gemmy appearance. The hexagonal prism/pyramid shape of these crystals is consistent with quartz, but is not consistent with diamond (which has cubic, or cube-related shaped crystals).
