Identifying genuine Herkimer Diamonds requires an understanding of their characteristics, as these unique quartz crystals can sometimes be confused with other minerals or quartz types.
First, look for the double termination. True Herkimer Diamonds have naturally formed points at both ends, setting them apart from most other quartz crystals. This feature is a hallmark of their authenticity.
Clarity is another key indicator. Herkimer Diamonds are known for their exceptional transparency, often being water-clear. However, they can also have inclusions like carbon, anthraxolite, or even water bubbles, which are natural and do not detract from their value but rather add to their uniqueness.
The natural faceting is due to their growth environment; they form 18 facets naturally, which give them their diamond-like appearance. This faceting should not be confused with the cutting done on actual diamonds.
Hardness is a good test; Herkimer Diamonds rank at 7 on the Mohs scale, significantly harder than glass but not as hard as diamonds, which are at 10. They should not scratch easily but will scratch glass.
Location is crucial; genuine Herkimer Diamonds are only found in Herkimer County, New York. Be wary of similar quartz crystals from other locations claiming to be Herkimers.
Price can also be an indicator. While not as expensive as diamonds, genuine Herkimer Diamonds have value due to their rarity and clarity. Extremely low prices might suggest they’re not genuine Herkimers.
Finally, if you’re buying or collecting, consider certification or purchase from reputable sources. Dealers who specialize in Herkimer Diamonds will often provide information about the crystal’s authenticity, origin, and any unique features like inclusions.
Identifying Herkimer Diamonds is part of their charm, blending the thrill of discovery with the appreciation of nature’s craftsmanship.
