About Herkimer Diamond

Herkimer diamonds are naturally double-terminated quartz crystals most famously associated with Herkimer County, New York.

Despite the name, they are not diamonds. They are quartz crystals valued for their brightness, natural faceting, and distinctive pointed terminations at both ends. Many contain veils, rainbows, fluid inclusions, carbon, or other natural internal features.

Symbolism

Herkimer diamonds are traditionally associated with clarity, amplification, alignment, and spiritual connection.

They are often chosen for meditation, manifestation, and intention-setting because they are believed to strengthen focus and amplify the energy of surrounding stones.

Care

Herkimer diamonds have a Mohs hardness of 7, making them suitable for many types of jewelry.

Avoid hard impacts, harsh chemicals, sudden temperature changes, and prolonged ultrasonic cleaning, especially when the crystal contains internal fractures or inclusions. Clean gently with mild soap, lukewarm water, and a soft cloth or brush.
