Guide to The Herkimer Diamond Mines – 2021 Season

It’s fair to say the pandemic has unraveled travel plans, putting our much-needed vacations on hold. Most of us haven’t left our homes since last March, and boredom has long-ago set in. Looking back on the uncertainty of last year makes us all the more excited to welcome a new spring season; and the re-opening of The Herkimer Diamond Mines on April 15, 2021.

Even before the pandemic sent us searching for road trip destinations and socially distanced outdoor adventures, interest in prospecting and rockhounding had been on the rise over the past few years. The fun and excitement will undoubtedly continue this year as more of us leave the isolation of our homes and take to the road again.

True, Herkimer Diamonds aren’t actual diamonds. They are beautiful double-terminated quartz crystals found in the Herkimer, New York area. These magnificent works of nature are close to 500 million years old and formed primarily within dolomite limestone rock. They have a diamond-like clarity and geometrical shape, thus the name “Herkimer Diamond.” You can read about Herkimer Diamonds and learn about their geology and history in Uncovering New York.

What’s New, Different, and Still Loved at The Herkimer Diamond Mines in 2021

Get Outside!

One facet of The Herkimer Diamond Mines that we’ve always treasured is the wide-open, albeit a little rocky, access to the above ground surface mines. These spaces allow for social distancing and all-day enjoyment of the great outdoors. Plan your visit during the spring season and you’ll be treated to a bounty of budding trees and green grasses blanketing the ledges on top of the mines and on the surrounding creek bed.

Beginning April 15, 2021, the Village Hall (Registration) and Prospecting Area (Mining) will be open daily from 9 a.m. to 5 p.m. Admission to the Mines is $14 per person (ages 13 and up), and $12 per person (ages 5 to 12). Children 4 years and under are free.  As in years past, your admission includes an all-day prospecting wristband ticket, use of a two-to-three-pound sledge hammer to break the dolomite limestone in the mines, and plastic baggies to hold the Herkimer Diamonds you find. Goggles are recommended and are available for purchase. It is also recommended that guests wear closed toe shoes and dressing according to the weather.

Depending on your level of interest, we recommend setting aside between two and eight hours for you visit.

Mining for Herkimer Diamonds is easy, and can be enjoyed by family members of all ages. Beginners and young children will have the best luck at discovering loose quartz crystals by searching the ground, flipping rocks, and sifting through loose material. If it’s sunny, you may notice surface crystals sparkle as you walk. Surface crystals usually ranging from the size of a poppy seed to a pencil eraser are also in abundance and more easily spotted after a rain storm when the dirt is gently disturbed by the rain drops.

For more advanced miners, try your luck at finding Herkimer Diamonds within the porous dolomite limestone rock that fills the mines. Look for a rock covered with small dark holes. These holes are called “vugs,” and are most likely to contain Herkimer Diamonds. Strike the rock with your hammer and be sure to check each piece that breaks off.  If you discover a Herkimer Diamond within a rock, it’s best to leave it in place unless it wiggles like a loose tooth. Trying to forcibly remove it from the rock could fracture the crystal. Herkimer Diamonds are just as valuable when left attached to their host rock.

Remember, as long as you can carry it out of the mine, you can keep everything you find!
