What is a Herkimer "Diamond"?

A Herkimer "Diamond" is not a real diamond, but a particularly clear, naturally double-terminated rock crystal (quartz). It was first found in Herkimer County (New York, USA) and received the trade name "Herkimer Diamond" due to its intense brilliance, purity, and typical double termination.
The tourmaline inclusions visible in the stone are natural formation features and make each piece unique.
