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

How to find crystals in Connecticut
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
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.
