Offered here is a natural double-terminated Herkimer Diamond quartz crystal, sourced from the world-famous Herkimer County.
Herkimer Diamonds are uniquely known for forming naturally double-terminated, meaning the crystal grew freely with termination points on both ends — a highly desirable characteristic among mineral collectors.
This specimen features excellent clarity and a distinct internal rainbow inclusion, visible when light passes through the crystal. These rainbows are caused by natural internal stress fractures and are considered a prized visual feature, making each piece completely one-of-a-kind.
