Chester County

Chester County is another great place for rockhounding in Pennsylvania since here you can find pyrite, the rare pyromorphite, quartz, fossils, and plenty of other things

What Crystals are Found in Pennsylvania?

The state of Pennsylvania shines in its diversity of minerals and crystals. You can find quartz crystals, rutile, rare pyromorphite, azurite, kyanite, eastonite, and plenty of other rare and beautiful crystals, all coming in different shapes and sizes!

Let’s see exactly where you can find some of the essential crystals in Pennsylvania!

Quartz Crystals

Quartz crystals can be found in a couple of places in Pennsylvania. You can start by going to Lancaster County and searching for it between the towns of Columbia and Mountville, in The Mud Grubb Lake mine. In Chester County, you can find quartz at the Brookdale Mine in Phoenixville or at the Rossville Road Cut. 

Some other great locations to find quartz crystals include the McAdoo woodland region or the Historic Crystal Cave in Kutztown; however, you must pay a fee here to collect specimens.


Quartz with Rulite Inclusion
Quartz with Rutile Inclusion

To find rutile, you can search for it in the Gross Road region; however, you need permission from the owner first. Rutile crystals can also be found near the Maryland state line, near Fawn Grove on Route 851.

Parkesburg is also a great place, and you can also pan for it in the nearby streams.


Coming in various colors such as white, dark green, light green, brown, yellowish-green or greenish-white, orange or grey, pyromorphite also comes in different shapes, such as barrel or hexagonal.

You can find this beautiful crystal in places such as the Wheatly Mines in Phoenixville town, in Chester County, or the Brookdale Mine in Phoenixville. It is a bit of a rare crystal to find, but the effort is worth it!


When it comes to azurite, the whole eastern region of Pennsylvania seems to be abundant in it. Beautiful blue azurite can be found in Lebanon County, at the Cornwall Mines, or at the Rossville road cut, but you will need a heavy hammer to do the trick!

TIP: One of the basic ways of determining a particular rock type is by testing its hardness. For the most accurate determination of rock hardness, it is advisable to use a Mohs scale test kit. Check out the best Mohs scale test kits in the article below:

What is Pennsylvania’s state rock?

The state of Pennsylvania currently hasn’t yet designated an official state rock for its region. Although Pennsylvania shines in its mineral and crystal diversity, when it comes to rocks, it doesn’t have any particular type that would be of great interest.

What is Pennsylvania’s state mineral?

The official state mineral of Pennsylvania hasn’t been decided yet; though numerous conventions and scientific works were put together to settle the matter, the sheer diversity of minerals found in this state make it quite difficult for one to be nominated. Eastonite, for example, is quite a rare mineral in the world, and it may be a good candidate.

What is Pennsylvania’s state gemstone?

When it comes to gemstones, the state of Pennsylvania hasn’t yet official designated a state gemstone of its own. Garnets may seem like a plausible candidate; however, the matter is far from settled. Establishing an official item for a particular state is sometimes a tremendous and tedious task.

What is Pennsylvania’s state fossil?

Although Pennsylvania doesn’t have an official state rock, mineral, or gemstone, it does have an official state fossil. The official state fossil of Penssylvania is the trilobite fossil Phacops Rana, since 1988.

This small sea creature can be found throughout the state. They inhabited this region, with plenty of them being discovered in 570 to 365 million years old Paleozoic rocks, especially in the central areas of the state.


The state of Pennsylvania may not offer much in terms of rocks, but it shines in its diversity of crystals and minerals. It is a great region where rockhounding is permitted, or permits can be obtained to explore some incredible locations and find specimens of equal measure.
