We can help you get started with some places you can explore for crystals below!
Crystals you can find in the US
The United States offers a wide range of crystals that reflect its diverse geology. From vibrant gems to more subtle mineral formations, there’s something to discover in nearly every region.
Calcite
With a variety of forms and a unique property of double refraction, calcite allows objects viewed through the crystal to appear doubled. This mineral can appear in a spectrum of colors, with pure forms typically being transparent or white.
In addition, calcite reacts vigorously with acids, which aids in distinguishing it from other minerals. It also frequently contributes to the structure of sedimentary rocks such as limestone.
Gypsum
Gypsum’s notable softness allows it to be easily scratched with just a fingernail, often presenting as white or very light-colored in its pure form.
It manifests in both crystalline forms, like selenite, and massive forms such as alabaster, making it versatile in use and appearance.
Gypsum is also essential in the construction industry and is a key component in the manufacture of plaster and drywall.
Fluorite
Fluorite comes in a wide range of vibrant colors, including purples, greens, blues, and yellows, and is known for forming in well-defined cubic crystals.
Beyond this, fluorite exhibits fluorescence under ultraviolet light! It can also be used in various industrial applications, including as a flux in steelmaking.
Galena
Galena distinguishes itself with a metallic luster and high density, typically found in a cube-like form. It serves as the primary ore of lead, making it important in the metal industry, while its shiny, silver color attracts collectors.
Not only does its appearance make it a subject of interest, but its weight and texture provide tangible lessons in mineral density and metallic properties. Galena also often contains traces of silver, adding to its commercial and educational value.
Corundum
Corundum is a mineral that comes in a variety of colors, though it is typically transparent or gray. Its most famous forms are sapphires and rubies, which are prized for their vibrant blue and red hues.
The mineral is known for its remarkable hardness, ranking just below diamond on the Mohs scale. This durability makes corundum ideal for industrial abrasives and cutting tools, as well as a popular choice for fine jewelry.
Quartz
Quartz is among the most common minerals in the Earth’s crust and is prized for its durability and variety. It forms in a wide range of colors and types, from clear rock crystal to purple amethyst.
The mineral is notable for its hardness and durability, which contribute to its use in a variety of applications. Quartz is also popular in the manufacturing of electronics and watches due to its piezoelectric properties, which allow it to convert mechanical pressure into electrical energy.
Pyrite
Often mistaken for gold due to its metallic luster and pale brass-yellow hue, pyrite is known colloquially as “fool’s gold.” Its characteristic cube-shaped crystal formations look man-made but are actually completely naturally formed!
Pyrite also has historical importance in producing sulfur dioxide for sulfuric acid production.
Rhodochrosite
Rhodochrosite stands out with its rich pink and red hues, making it highly desirable as both a mineral specimen and a gemstone.
It typically forms in layered or stalactitic structures, with bands of colors that showcase how it grew over millions of years.
Beyond its beauty, rhodochrosite is significant as the main source of manganese, an essential element used in metal alloys.
Rhodonite
Appreciated for its deep pinks and reds, often complemented by black manganese oxide veins, rhodonite presents a dramatic appearance. It is typically found in metamorphic rocks and is used both as an ornamental stone and in jewelry.
In geology, rhodonite is significant for its role in metamorphic processes and its association with other manganese-rich minerals. It can be found in metamorphosed sedimentary rocks and is sometimes used as an indicator of the presence of manganese deposits.
Vivianite
Vivianite, an iron phosphate mineral, emerges in low-oxygen environments like peat bogs or iron-rich deposits. Its striking blue to green color, which can change to a lighter shade over time due to oxidation, makes it a distinctive mineral.
Found in various geological settings, vivianite provides clues about the local conditions and the presence of phosphate deposits.

What rough crystals look like
When you’re out looking for crystals on your own it’s important to know what you’re looking for. This is what you need to look out for:
Look for exteriors like this
When you’re out searching for crystals in the wild, it’s essential to keep in mind that what you find won’t look like the polished stones you see in stores. One important tip is to consider what certain crystals look like in their raw, natural form.
Without the shine and smooth finish, crystals might appear rough, with jagged edges or earthy tones masking their true beauty. Understanding this can help you spot potential finds that might otherwise be overlooked.
Examine the crystal structure and shape
Crystals often form in specific geometric patterns that can be key to identifying them. For example, quartz is known for its hexagonal prisms, while halite typically forms cubic shapes.
By recognizing these distinct patterns, you can differentiate between various types of crystals and better understand what you’ve found.
Observe color
Some crystals are known for their distinct hues, like the deep purple of amethyst or the vibrant green of emerald. However, not all crystals will have strong colors; some may be clear or only slightly tinted.
Check the luster
Luster refers to how a crystal’s surface interacts with light. Some crystals might have a shiny, glassy luster, while others may appear metallic or dull. This characteristic can help you determine the type of crystal you’ve found.
However, it’s important to remember that luster isn’t always obvious right away. In some cases, a crystal’s true luster will only become apparent after it’s been cleaned or polished, so keep this in mind as you examine your finds.
Evaluate the transparency
Pay close attention to how much light passes through the crystal. Some crystals are completely clear, allowing light to pass through easily, while others may be opaque and block light entirely.
You might also encounter crystals with translucent edges but opaque centers. These variations in transparency can offer valuable clues about the type of crystal you’ve found, making it easier to identify and appreciate your discovery.
A Quick Request About Collecting
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
Tips on where to look
Having a better idea of where to look can greatly narrow down your search and increase your chances of finding crystals. By focusing on environments where crystals are likely to be exposed, you can spend less time searching and more time discovering.
Outcrops and Exposed Rock
Rocky outcrops are prime locations for finding crystals and minerals. Search along the edges of outcrops, particularly where erosion has worn away the surrounding soil, revealing the rock underneath.
Pay close attention to any visible cracks, crevices, or small cavities within the outcrop, as these are often where crystals develop and can be extracted with minimal effort.
Stream Beds and Gravel Deposits
Stream beds are dynamic environments where water flow constantly shapes the landscape. Over time, water can erode rocks upstream, breaking them down and carrying mineral fragments, including crystals, downstream.
When searching in these areas, look for spots where the current has slowed, such as bends in the stream or areas behind large rocks, as these are prime locations for deposits.
Quarries and Mines
Quarries and mines are excellent places to search for crystals because they expose deep layers of rock that would otherwise be hidden beneath the surface. These sites often contain a variety of minerals and crystals that have been brought to the surface during excavation.
Pay attention to tailings piles, where waste rock is discarded, as they often contain overlooked or broken crystals. Always prioritize safety when exploring these areas and ensure that you have permission to search.
Road Cuts and Construction Sites
As roads are cut through hillsides or construction projects dig deep foundations, layers of rock and soil that have been undisturbed for millions of years are suddenly exposed.
Look for freshly exposed rock faces, especially where blasting has occurred, as this can create fissures or expose pockets filled with crystals. Be cautious around active construction sites, and always seek permission before exploring.
Mountainous Areas
In mountainous regions, erosion caused by wind, rain, and ice can wear away the softer rock, exposing harder crystals that have formed within. Focus on weathered and broken rock formations.
Look for scree slopes, where loose rock has accumulated at the base of cliffs. Additionally, areas near fault lines or volcanic vents are particularly promising, as they often have a higher concentration of minerals.
