Herkimer Diamond FAQ:

What are Herkimer Diamonds? 

A Herkimer Diamond is a type of quartz crystal that is found in Herkimer County, New York, USA. It is known for its distinctive double termination (point on both ends) and exceptional clarity, and is often used in jewelry and for spiritual or healing purposes. Herkimer Diamonds are not true diamonds, but are named for their diamond-like appearance.

What makes Herkimer Diamonds valuable?

Herkimer diamonds are valued for their natural beauty and unique characteristics. Some of the factors that contribute to their value include:

  1. Clarity: Herkimer diamonds are known for their high degree of transparency, which makes them appear to glow when illuminated.

  2. Shape: The double-terminated (pointed at both ends) shape of Herkimer diamonds is considered rare and adds to their beauty and value.

  3. Hardness: Herkimer diamonds are made of quartz, which is a hard mineral (Mohs hardness of 7) that makes them durable and suitable for use in jewelry.

  4. Rarity: Herkimer diamonds are only found in a few locations around the world, with the majority being found in Herkimer County, New York. This scarcity contributes to their value.

In addition to these factors, Herkimer diamonds are also believed to have metaphysical properties, such as promoting clarity and peace of mind, which adds to their appeal for some people.

Are Herkimer Diamonds real diamonds?

No, Herkimer diamonds are not real diamonds. They are a type of quartz crystal that is named after Herkimer County, New York, where they are primarily found. The name "Herkimer diamond" is used to describe their clear, diamond-like appearance, but they are not actual diamonds. Diamonds are a different mineral, made of carbon, and are much harder and more valuable than quartz.

How much is the average Herkimer Diamond worth?

The value of a Herkimer diamond can vary depending on several factors such as size, shape, clarity, and quality. The average price for a small, lower quality Herkimer diamond can range from $5 to $20, while larger, higher quality crystals can cost several hundred dollars or more. However, the price of Herkimer diamonds can also be influenced by market demand, so the actual value can fluctuate. It is important to note that while Herkimer diamonds are often marketed as "diamonds," they are not actual diamonds and therefore do not have the same value.

How are Herkimer Diamonds Formed? 

These crystals are formed through a process of sedimentary deposition and hydrothermal activity. Herkimer County was covered by a shallow sea. Over time, layers of sediment built up on the sea floor, eventually forming a layer of sedimentary rock known as dolostone.

As the dolostone was forming, hot, mineral-rich fluids were forced up through the rock from deep within the Earth. These fluids carried dissolved silica, which was deposited in the dolostone in the form of tiny quartz crystals. Over time, these crystals grew and merged together to form the larger, double-terminated quartz crystals that are known as Herkimer diamonds.
