Herkimer Diamond Quartz Crystal | Double-Terminated Quartz | New York, USA | A24

Herkimer Diamonds are among the most recognizable quartz crystals in the world. Despite their name, they are not diamonds—they are exceptionally clear, naturally double-terminated Quartz crystals found primarily in Herkimer County, New York. Their remarkable clarity and naturally formed crystal points have made them favorites among mineral collectors for generations.

Some of the Herkimer Diamonds in this collection also contain natural black inclusions known as anthraxolite. These fascinating inclusions formed millions of years ago and are a sought-after feature that makes every specimen even more unique.

In traditional crystal practices, Herkimer Diamonds are associated with mental clarity, manifestation, heightened awareness, and energy amplification. Many people choose them as symbolic reminders to focus their intentions and cultivate a clear mind. These metaphysical properties are shared as part of longstanding crystal traditions.

Herkimer Diamonds are composed of silicon dioxide (SiO₂), the same mineral as Quartz found around the world. What makes them special is their exceptional natural clarity and the fact that they commonly form with two naturally terminated ends rather than one. These crystals developed approximately 500 million years ago within cavities in Cambrian-age dolostone, where they grew freely without being attached to surrounding rock.
