Herkimer Diamond (Quartz Crystal) – The double terminated quartz crystals discovered around Herkimer County, New York are known as Herkimer Diamonds. These crystals are known for their extreme clarity but are also seen with inclusions; a rare water pocket inclusion and a common black carbon speckled pattern inclusion. The US Herkimer Diamonds are famous for their strong refractive shine which is met only by few other double-terminated quartzes in the world, such as stones from Himalaya and a few Brasilian findings.
