The state of Wyoming is known for its rough scenery and abundance of natural resources. But there is a beautiful secret hidden below the ground: diamonds! The Earth’s mantle is where these precious stones are made.
We will show you where diamonds have been found, give you help on how to recognize these valuable stones, and demonstrate the usefulness of the tools you’ll require.
This article will help you understand and explore Wyoming’s diamond-rich potential, whether you’re a curious explorer, a future geologist, or someone who wants to find their diamond. Join us, and let’s start this exciting journey together!
What Is Wyoming Diamond Anyway?
Diamonds are known for being strong and beautiful, and they are also one of the hardest natural things on Earth. They are made up of only carbon, which is the same element that makes up graphite.
But the way these carbon atoms are grouped is what makes diamonds unique. Deep in the Earth’s core, where it’s very hot and pressurized, these carbon atoms join together in a special way to make a crystal lattice that makes diamonds so hard. It’s like a team of atoms holding hands so tightly that they’re almost impossible to break.
There are a lot of diamonds in places where these volcanic events happened. Large diamond mines have been set up in these areas to get these valuable stones. The location where you found specimens can also affect how much a diamond is worth.
Rivers can also transport diamonds to locations further away from where they formed in volcanoes. Here’s our guide to identifying diamonds to make your search easier.
- The deep experience and understanding of our team about the area
- Recommendations from local groups and clubs
- How easy it is to get the a particular location
- Safety and potential hazards when collecting
- Weighing private and public locations
- The ability for both experienced and novice geode enthusiasts to find great samples
With these factors in mind we’ve been able to put together a fantastic list that just about anyone can use!
The Best Places To Find Diamond in Wyoming
We should talk about the best places in the state to find diamonds. They have a lot of great places to mine for gems in Wyoming, but only a few are good for finding diamonds. Certain places aren’t well known, but it’s usually not hard to find them.
Always Confirm Access and Collection Rules!
Before heading out to any of the locations on our list you need to confirm access requirements and collection rules for both public and private locations directly with the location. We haven’t personally verified every location and the access requirements and collection rules often change without notice.
Many of the locations we mention will not allow collecting but are still great places for those who love to find beautiful rocks and minerals in the wild without keeping them. We also can’t guarantee you will find anything in these locations since they are constantly changing.
Always get updated information directly from the source ahead of time to ensure responsible rockhounding. If you want even more current options it’s always a good idea to contact local rock and mineral clubs and groups
Boden Placer Deposit
People who want to look for diamonds will enjoy the Boden Placer Deposit in Wyoming. This area has a history of surprising geologists and treasure hunters with its secret gems.
It’s in the middle of Wyoming’s mineral-rich landscape. The Boden Placer Deposit is unique because of its unique geological past. Millions of years ago, volcanic action deep below the Earth’s surface made it possible for diamonds to form.
It was during these eruptions that diamonds were brought closer to the surface, where they finally settled in the Boden area.
There is a mix of gravel, sand, and other things in the Boden Placer Deposit, which is often a good sign that diamonds are close. If people are lucky and patient, this place is like a natural treasure chest where they can dig through the dirt and maybe find a gem hidden among the rocks.
Where we found diamond at the Boden Placer Deposit
Placer deposits are places where valuable rocks or gems have been pushed to the surface by natural forces, like moving water. As with other gemstones, diamonds can sometimes be found in placer deposits in places where they are known to be found.

Cedar Mountain
Diamond hunters will find Cedar Mountain in Wyoming to be an interesting place to visit. Even though Cedar Mountain is in an area known for its variety of geological features, it stands out because of its own past and make-up.
Millions of years ago, volcanic action below the surface of the Earth made it possible for diamonds to form. When these old volcanoes exploded, they brought valuable diamonds closer to the surface.
Over time, weathering and water flow have moved these diamonds around. Some of them have ended up near Cedar Mountain.
Where we found diamond in Cedar Mountain
The kimberlite pipes in Cedar Mountain make it a good place for people looking for diamonds. A certain type of rock called kimberlite often brings diamonds from deep inside the Earth to places where people can find them.
Iron Mountain
Another beautiful place to look for diamonds is Iron Mountain in Wyoming. Because this area is known for having a lot of different minerals and rocks, it could also be a place where diamonds are kept.
Iron Mountain got its name from the large amount of iron ore. However, diamond hunters are more interested in the mountain’s natural history. Some diamonds ended up in places like Iron Mountain.
Explorers and rock fans will love Iron Mountain because it’s a beautiful place to be outside, and there is a chance that they might find a diamond in the rocks there.
Where we found diamond in Iron Mountain
It’s possible to find them in places with volcanic rock formations, especially kimberlite or lamproite pipes, which are known to bring diamonds from deep inside the Earth to the surface.
Also, river or stream beds close to these types of formations could be possible places because of the way that erosion moves materials naturally.
Common Diamond-Hunting Questions
If someone wants to know where to find diamonds in Wyoming, they often ask the following:
Is it illegal to collect diamonds in Wyoming?
Whether or not it’s possible to collect diamonds or any other minerals depends on who owns the land and the rules that apply in that area.
