Long Hill Mine in Old Mine Park is Our Favorite Crystal Mine in Connecticut

A look at the Old Mine Park land formations

Trumbull, Fairfield County, CT

The Long Hill Mine in Old Mine Park was a major source of mica and feldspar in the 1800s and early 1900s. It was active for over 60 years, and during that time, it produced some of the finest quality minerals in the country. In fact, some of the minerals found here are still highly sought after by collectors today.

Old Mine Park, where Long Hill Mine is situated, is located on a ridge of metamorphic rock. The rocks in this area, being over 400 million years old, are rich in minerals that have been exposed to weathering and erosion over time, resulting in a rich deposit of crystals just waiting to be uncovered.

Long Hill Mine has a reputation for producing some of the most diverse, beautiful, and high-quality crystals in our state. Since it’s easily accessible, it’s perfect for both beginner and experienced collectors. If these reasons are not enough to justify this mine’s place in our top recommendations, Long Hill Mine is also a great spot for gem mining in Connecticut.

Where we found crystals at Long Hill Mine at Old Mine Park

If you’re here to find crystals, go 1 mile south of railroad station where you will find Calcite, Fluorite, Pyrite (cubes), Topaz (blue), and other crystals.

The tools every crystal hunter will need

When you're out looking for crystals having the right tools for the job is very important. You don't need a lot for most trips but there are a handful that are critical and will make your life a lot easier.

We get asked a lot about the equipment we use. Over the years we've found a handful of tools that we recommend to both new and experienced crystal miners which we outline in great detail in our complete rockhounding supplies guide. These are quality options that also happen to be relatively inexpensive.

Below are the basic tools that make your life so much easier and save you a ton of time. Check out the full guide to see everything we recommend bringing. One quick note, as an Amazon Associate I earn from qualifying purchases but we try very hard to only recommend gear we would use ourselves and often recommend brands you can't find on Amazon.

At a minimum you should have:

1 - Sturdy rock hammer: The Estwing Rock Pick is our standard

2 - Rugged chisels: Try Kendo' 3-piece Chisel Set

3 - Compact shovel: The Koleiya 28-inch shovel works well

4 - Rock screen pan: The Wazakura Soil Sieve Set fits the bill

5 - Eye protection: DeWalt Safety Glasses are cheap and comfortable

6 - Head protection: Malta's Safety Helmet has been our go-to

7 - Jewelers lens with at least 20x magnification: Jarlink's Jewelers Loop is perfect

The crystal-finding books that we use most

There are also a few books that have been extremely helpful in the search for gems. These books have great recommendations and tips:

Litchfield County, CT

Bantam Lake was formed over 10,000 years ago during the last ice age. It was a vital resource for the indigenous people who lived in the area, and artifacts from their settlements have been found nearby. In the 1800s, the lake became a popular tourist destination, with visitors coming to fish, hunt, and enjoy the natural beauty of the area.

Located in the Litchfield Hills, which are part of the Appalachian Mountain range, Bantam Lake is rich in metamorphic rock that has been subjected to intense heat and pressure over millions of years. This has resulted in a variety of crystals here.

The lake is surrounded by numerous hiking trails and is easily accessible, making it a perfect spot for rockhounding.

Hamden, New Haven County, CT

Pine Rock Quarry is packed with interesting geological features and is a must-visit destination for anyone interested in rockhounding. This place dates back to the 1800s when it was primarily used for mining granite. In the mid-20th century, it was converted to a landfill and later closed— but not for rockhounding!

The area of the quarry is rich in pegmatites, which are geological formations that can contain a wide variety of minerals. These pegmatites have produced a stunning array of different crystals.

Since a handful of our recommended places cover wide areas, we’ll help you narrow down and focus your search on the surest spots where crystals are usually found. We recommend visiting these spots first when you go here:

Mines and Mine Dumps

Searching for crystals in mines and mine dumps can be an incredibly fruitful experience. Mines are locations where minerals are extracted from the earth, and mine dumps are the piles of rock and debris left over from the mining process. These dumps can contain a variety of highly-concentrated minerals and crystals that were unearthed during the mining process, giving you a better chance of finding something amazing. Additionally, mines and mine dumps can be great spots to find rare and unique specimens that you may not find elsewhere.


Quarries are locations where large amounts of rock are excavated for building materials, landscaping, and other purposes. They can contain a wide variety of minerals and crystals that were formed deep in the earth and brought to the surface during the excavation process. These minerals and crystals can range from common to rare, making quarry hunting an exciting and rewarding experience.

Pay-to-Dig Mines

Pay-to-dig Mines, where you pay a fee to enter and collect specimens, offer the certainty of finding crystals in a controlled and supervised environment. Unlike natural rockhounding locations where there’s no guarantee of finding anything, pay-to-dig mines have been specifically chosen for their high mineral content. They often have well-maintained areas that have been specifically designed for crystal hunting.

In most cases, pay-to-dig mines provide tools and equipment to help you extract crystals from the ground. They also often have experts on-site to help you identify specimens and provide guidance on proper extraction techniques. This can be especially helpful for beginners who are new to crystal hunting.

Connecticut Crystal Mining Laws And Regulations

This is specially for guidelines imposed by the Connecticut Department of Energy and Environmental Protection which regulates the activity here. Always make sure to obtain any necessary permits or permissions from concerned public and private offices and individuals, depending on the kind of land you plan on exploring. Also, be mindful of any regulations that aim to protect the environment and biodiversity of our state. At the end of the day, respecting these laws will allow crystal mining to remain a legal and sustainable activity here.
