Herkimer Diamond Jewelry – Everything You Need to Know

A unique, rare and little-known gemstone, Herkimer diamonds are a delightful stone to add to your collection. But although this gemstone has a diamond-like appearance, high brilliance and sparkle and very good durability, it’s not an actual diamond.

So, what exactly is it?

Let’s take a look at Herkimer diamonds in closer detail.

What are Herkimer Diamonds?

A Herkimer diamond is a type of crystal that at first glance looks like a diamond. However, it’s not a diamond at all and has very different properties.

Herkimer diamonds have been used for centuries as gemstones, amulets and in the making of tools. They are some of the oldest gemstones, estimated to be around 500 million years old!

Composed of quartz, Herkimer diamonds are doubly terminated crystals with termination points on either end of the rock. They are known to have 18 naturally occurring facets. Unlike real diamonds, however, Herkimer diamonds are mined above ground, making them more ethical and sustainable than mined diamonds.

Most crystals grow with a lot of reliance on the host rock, however Herkimer diamonds have little contact and grow almost on their own, often in clay deposits. This makes them rare and highly popular among gemstone lovers and mineral collectors.

Are Herkimer Diamond Real Diamonds?

No, they are not. The name Herkimer diamonds is a misnomer because these aren’t diamonds at all. They’re quartz crystals. The Herkimer diamond gets its name from the fact that large deposits were found in Herkimer County, New York. However, you can also find deposits in China, Norway, Afghanistan and Ukraine.

Those who aren’t aware of this can be fooled into thinking that Herkimers are diamond crystals as the stone can look like a diamond to the untrained eye. The retailer must make sure that they have clearly explained this difference to the customer.

4Cs of Herkimer Diamonds – Cut, Color, Clarity and Carat

When buying a Herkimer diamond, consider the 4cs. Here’s a quick overview of the 4cs of a quality Herkimer diamond.

Herkimer diamonds are hard enough to be cut into most gemstone shapes. They are commonly faceted to accentuate their sparkle, but they can also be cut en cabochon or used in their raw state.

These stones are almost always transparent and have very good clarity. However, sometimes specimens can contain impurities and flaws such as air bubbles, black carbon deposits or rainbow inclusions. High quality Herkimer should be eye-clean.  

These gemstones can vary in color from transparent and colorless to smoky. The colorless variety looks very similar to diamonds but are more glass-like and don’t contain the depth and brilliance that is associated with diamonds. However, high quality specimens have impressive brilliance especially when viewed under natural light.

Herkimer diamonds come in a variety of sizes and can be found used in jewelry in small or heavier carat weight. Because this is a rare gemstone, large Herkimer stones can be relatively expensive.

The value of the Herkimer diamond is determined by the above 4Cs. Prices can range depending on the quality of the gemstone and the workmanship of the jewelry. In general, most Herkimer jewelry is reasonably priced but high-quality pieces can cost thousands of dollars. This 50 carat Herkimer pendant is an example of that.

Some retailers provide a certificate of authenticity to go with their Herkimer diamond jewelry. Check with your retailer prior to purchase if they provide a certificate, if you’re worried about buying low quality or fake Herkimer diamonds. Sometimes retailers list the Herkimer diamond as a diamond in their jewelry descriptions, which can be misleading so always enquire if you have any doubts.

Are Herkimer Diamonds Good for Engagement Rings?

Herkimer diamonds rank at 7.5 on the Mohs hardness scale, meaning that they are hard enough for regular wear. While they make good diamond substitutes, they’re nowhere near as hard as diamonds. But they are still ideal for daily wear in special jewelry, like engagement rings or wedding rings.
