Herkimer Diamond
Despite the name, Herkimer Diamond is not a diamond at all — it's an exceptionally clear, naturally double-terminated quartz found almost exclusively in Herkimer County, New York. Each crystal grows with eighteen natural facets and two perfect points, emerging from the rock already "finished," with a brilliance that rivals cut gemstones. Mined from 500-million-year-old dolomite, these pocket-sized marvels are among the most distinctive quartz in the world.

What Is Herkimer Diamond?
Why Collectors Love Them
No two Herkimers are alike: many contain sparkling carbon inclusions, tiny fluid-filled "enhydro" chambers, or rainbow flashes. Their natural double termination — rare in quartz — means they're ready to wear or use with no cutting required. Because they're typically sold as small raw crystals, handle them as the delicate natural specimens they are.
