What is a Herkimer Diamond Everything You Need to Know

Do you know what is a Herkimer diamond? Even though people call it a diamond, it is not a precious gem at all but a double terminated crystal found in the Mohawk River in New York state. The Mohawk Indians lived in Herkimer County for centuries, and they knew about this beautiful quartz crystal and considered it magic.

Gem collectors love this high vibration stone because of its 18 facets and two constant points. Since quartz typically has only one termination, Herkimer Diamonds are a unique exception. Most of them are colorless, but you can sometimes find pieces in various colors.

What are Herkimer Diamonds?

Herkimer diamonds (Stone of Attunement) are quartz crystals with the typical hexagonal quartz form. However, they are doubly terminated instead of terminated on their one end.

While quartz crystals’ hexagonal structure makes them elongated, Herkimer diamonds appear extended more apparently thanks to the two faceted (pointed) ends.

The Mohawk Indians found these diamonds in the 15th century in rocks and water streams in Herkimer County. Still, you can also look for them in Arizona, Canada, England, Norway, Germany, Ukraine, Afghanistan, and China.

Rare, doubly-terminated naturally faceted quartz crystals with diamond-like geometrical shapes appear without much contact with the host vuggy rock. They always have 18 facets and two termination points.

Perfect Herkimer diamonds are less than 1 inch (2.5 cm) long, but you can find much larger crystals occasionally. They are usually clustered, and tiny crystals are often attached to the larger pieces.

Crystals have outstanding clarity, but some stones contain impurities like air bubbles, rainbow inclusions, or black carbon deposits. Their color ranges from colorless to smoky, and high-quality pieces have impressive brilliance under natural light.

Unlike other crystals that rely on the host rock while growing, Herkimer diamonds often grow in clay deposits. You should know that no all Herkimer diamonds are the same. Some crystals can contain:

  • Decayed plants
  • Rare Enhydro crystal with a captured water bubble inside
  • Anthraxolite, black coal-like pieces
  • Enhydro crystal with an anthraxolite floating in the bubble
  • Twins, skeletal, clusters, and phantom crystals in rare cases

Questionable Name

The term Herkimer diamonds is a misnomer since it is about quartz crystals, not real diamonds. However, locals and the mineral community have used it for more than a century.

Since that name is ingrained in the language, there is no need to make any sudden changes. On the other hand, it can mislead some people and convince them that the stone’s value is higher than it really is. For that reason, it is necessary to let the buyer know about its real nature while selling it.

Otherwise, a merchant could have legal complications because of the inadequate use of a mineral name, according to the Federal Trade Commission announced in 2015. You can expect that the crystal’s name will likely be changed at some point.

Real Diamond vs. Herkimer Diamond

As you have already known, actual diamonds are found in a rough form that requires painstakingly cut to get smooth faces and a desired geometrical shape. On the other hand, Herkimer diamonds are beautiful as soon as you take them out of the rock or clay deposits.

A diamond scores a 10 on a Moh’s hardness scale, while Herkimer diamond quartz crystal reaches a 7.5. Unlike real diamonds buried deep underground, you can find Herkimer diamonds above ground.

Herkimer Diamond Price

Herkimer diamonds are highly appreciated for their unique crystal appearance, naturally faceted ends, extraordinary clarity, and healing properties. Their quality is determined by 4Cs (carat, cut, clarity, and color), like real diamonds. You can use them as display stones or for designing various pieces of jewelry.

Their price is far lower than diamonds’ value but is always significantly higher than the amount of money you need to set aside for semi-precious gemstones. On average, you will pay approximately $75 for a Herkimer diamond weighing 0.176 ounces (5 g), but rare big stones can cost a fortune.

The final price always depends on the crystal’s color, carat weight, clarity, cut, and retailer you want to buy it from. Keep in mind that you should look for a certified stone with appropriate documentation.
