Herkimer Diamond Geology and Geography. The host rock of "Herkimer diamonds" is the Cambrian-age, Little Falls Dolostone. The Little Falls Dolostone was deposited about 500 million years ago, and the "Herkimer diamonds" formed in cavities within the dolostone.These cavities are frequently lined with drusy quartz crystals and are often coated with a tarry hydrocarbon.
