Best Rockhounding Sites & Beaches in Connecticut
The best rockhounding sites and beaches in Connecticut are Hartford County, Litchfield County, Tolland County, Fairfield County, New Haven County, Middlesex County, and New London County. Collins Hill, Long Hill Mine, Tolland, Vernon, East Granby Quarry, Bristol Copper Mine, Roebling Mine, and Old Iron Mine are exceptionally great places.
Let’s explore a couple of these areas and see exactly why they are such great spots for rockhounding or beachcombing.
Litchfield County, Connecticut, is a fantastic region for rockhounding as there are many spots to choose from. For example, the area exposures of mica schist often reveal corundum, staurolite, pyrite, or talc specimens.
Rose quartz can be found on the south side of Bantam Lake. The Roebling Mine though, near New Milford, takes the cake. Here you can find tourmaline, aquamarine, beryl, biotite and feldspar minerals, garnet, smoky quartz, and muscovite.
Near Mine Hill, at Old Iron Mine, you can find quartz crystals, pyrite, galena, chalcopyrite, siderite, and sphalerite. If you want to find prehnite or agates, go to Torrington, in the area of basalt sills.
Hartford county is another excellent area for rockhounding in Connecticut. Here, if you head to the Bristol Copper Mine, chances are you will find chalcocite crystals, bornite, calcite, chalcopyrite, chrysocolla, or malachite.
Amethyst is commonly found in Canton, in the quartz vein exposure of the local stream. However, at the East Granby Quarry in Hartford county, you can find gem-quality datolite specimens, calcite, aragonite, calcite, celestine, epidote, fluorite, prehnite, galena, quartz, and various others things.
The area quarries near Meriden are also popular locations where amethyst, calcite, gypsum, and quartz specimens have been found. Aquamarine, and smoky quartz specimens, are located at old Simpson Quarry, Glastonbury.
The many outcrops and road cuts in Tolland county, Connecticut, are fantastic for rockhounding. In the Tolland and Vernon area schist exposures, explorers may find rose quartz specimens, alongside garnets, and staurolite specimens.
In Union, the road cut just south of Bigelow Pond is where you can find cordierite, moonstone, and feldspar.
Middlesex County, Connecticut, is home to numerous old mines and quarries. Some require fees, while others are free so it’s important to do your research beforehand.
One popular fee quarry here is the Gillette Quarry, Haddam. Here you may find garnet, quartz crystals, amazonite, aquamarine, beryl, chrysoberyl, and tourmaline.
At Collins Hill, the west side near peak, explorers may find spodumene, tourmaline, apatite, aquamarine, beryl, citrine, bismuthinite, columbite, feldspar, and rose, smoky, or clear quartz specimens.

|Aquamarine||Old Simpson Quarry, Roebling Mine, Riverside Quarry, Walden Gem Quarry|
Aquamarine is easily found in Connecticut. If you head to Litchfield County, at the Roebling Mine, you can find aquamarine at New Milford. In Hartford County, aquamarine is found at the Old Simpson Quarry, Glastonbury. Middlesex County is, however, the best region in Connecticut to find aquamarine gemstones.
You can head towards the Gillette Quarry, Haddam, but you can only enter by paying a fee. The Riverside Quarry also has aquamarine specimens, as well as the Walden Gem Quarry. You can also find aquamarine at Collins Hill, the west side near the peak.
When it comes to finding amethyst gemstones in Connecticut, your best luck is in either Hartford County or New Haven County. In Hartford County, you can find amethyst in Canton, in the quartz vein exposure in the local stream.

If they were discovered, diamonds would most likely have been brought here from other states through natural phenomena.
Gold, on the other hand, is just as hard to find in Connecticut. The most known occurrences took place in the northwestern parts of Litchfield County, in small glacial deposits. The Thomaston Dam at Leadmine brook, Farmington River northwest of Hartford, and Spruce brook have also minor placer gold deposits.
Garnets appear to be popular and numerous in Connecticut though. Almandine garnets are found throughout the state.

If you want to find rose quartz in Connecticut, head towards the south side of Bantam Lake, Litchfield County.
Smokey quartz can be found at the Roebling Mine, New Milford, or in Hartford County, at the Old Simpson Quarry, Glastonbury. You can also find quartz in this county at the area quarries in Meriden, or Canton, the exposures of Canton.
Tolland County though is a great place to find various types of quartz. For example, the Tolland and Vernon area schist exposure yields normal and rose quartz specimens.
In Middlesex county, you can find rose, smoky, or clear quartz specimens at the Slocum Prospect, East Hampton, or Collins Hill.
Crystals are also abundant in Connecticut. You can find in Connecticut crystals like corundum, quartz crystals, sphalerite, chalcocite crystals, chrysocolla, celestine, epidote, fluorite, cordierite, cerussite, graphite pyromorphite, arsenopyrite, bismuth, pyrite, topaz crystals, scheelite, citrine, bismuthinite, and spodumene.

What is the State Mineral of Connecticut?
The official state mineral of Connecticut is the almandine garnet, since 1977. They occur in igneous pegmatites, granites, and metamorphic gneiss or mica schist.
They are prevalent throughout Connecticut, hence why garnets are found all across the state. Garnets vary in color from dark tints to pale specimens, and some have strong hues of violet-red.
What is the State Fossil of Connecticut?
The official state fossil of Connecticut is the Eubrontes Giganteus, from 1991. It is a giant three-toed track, common in the Connecticut Valley, which is among the world’s best dinosaur track locations.
Based on the analysis, it might seem that the dinosaur that left these tracks is related to the western genus Dilophosaurus.
Connecticut is a small state with a big variety of gemstones, minerals, crystals, rocks, and especially fossils. It is a must-visit state for any die-hard rockhounding collector looking to discover new specimens or hunt for rare ones.
