💡 Good to know

Herkimer 'diamonds' are not diamonds. They are naturally double-terminated, very clear quartz crystals from pockets in Cambrian dolostone (about 500 million years old) around Herkimer County, New York. Several fee-dig mines let visitors collect. Some contain black bitumen or fluorescent petroleum inclusions.

✨ Metaphysical & Folklore

These are traditional and folk beliefs from crystal lore. They are not scientific or medical claims – crystals are not a substitute for professional care.

These doubly-terminated quartz crystals from New York are prized as stones of vivid dreams and attunement.
