All You Need to Know When Rockhounding in Iowa

Iowa, like many states in the U.S., has a rich history of rockhounding and gemstone exploration. Leaders of states with significant mineral deposits often establish state minerals, rocks, stones, or gemstones to promote interest in their natural resources, history, and tourism. 

For Iowa, the state rock is the Geode, which was officially adopted in 1967. Geodes are spherical rocks that contain hollow cavities lined with crystals. The state’s recognition of the Geode highlights its significance in Iowa’s geological and cultural history.

Iowa’s landscape is characterized by rolling plains and gentle hills, making it part of the Central Lowland of the U.S. This terrain was shaped by glacial movements, contributing to the state’s rich soil. 

The Mississippi River bisects the state and is home to several smaller rivers and lakes. Iowa’s diverse habitats, from wetlands to woodlands, support a variety of wildlife, including white-tailed deer, wild turkeys, and various other bird species.

The best times for rockhounding in Iowa are spring and fall when the weather is mild. These seasons offer comfortable temperatures and fewer crowds, making exploring and discovering the state’s geological treasures easier.

When rockhounding in Iowa, it’s essential to be environmentally conscious. Always obtain the necessary permits and permissions before collecting specimens. Avoid digging in protected areas and respect private property. Practicing “Leave No Trace” principles is crucial: pack out what you pack in, minimize the impact by sticking to established paths, and avoid disturbing wildlife.

Top 14 Gemstones in Iowa

With its rich geological history, Iowa has several gemstones that interest hobbyists and professionals. This article describes where to discover the qualities of the state’s most valuable gemstones.

Geodes

Geodes, often called Iowa’s state rock, can be predominantly found in the state’s southeastern part. Notable locations include the Keokuk area, along the Mississippi River, and the region surrounding the town of Fort Madison. These areas have become popular destinations for rockhounds due to the abundance of Geodes.

Varieties found in Iowa often have interiors lined with Quartz or, occasionally, Calcite. When hunting for Geodes, look for rounded rocks that might have a hollow sound when tapped. 

A hammer and chisel are essential for breaking open Geodes to reveal the crystal formations inside. Once you spot a potential Geode, the primary thing to do is to tap it to check for hollowness gently. 

Geodes are believed to aid in self-discovery and intuition. Their crystalline structures are thought to amplify and purify energies, making them popular meditation and spiritual healing tools.

Amethyst

While not as common as Geodes, Amethysts can be found in Iowa, particularly in the northeastern regions near the Mississippi River. Specific locations are harder to pinpoint, but diligent searchers might come across these purple gems in riverbeds or old mining sites.

When searching for Amethyst, watch for its distinctive purple hue, ranging from light lavender to deep violet. 

A shovel and a sieve can be handy tools when sifting through riverbeds. Upon finding a potential Amethyst, the first thing to do is to clean it gently with water to reveal its clarity and color. Iowa’s Amethysts might sometimes be smaller and less saturated than those in more famous locations.

Amethyst is renowned for its metaphysical properties. It’s often called the “Stone of Sobriety” due to its purported ability to enhance clarity of mind and reduce addictive behaviors. Many also believe it aids in spiritual growth and protection.

Chalcedony

Chalcedony is a stone found in many parts of Iowa. The best places to look are near the Mississippi River in the east, middle, and southern parts of the state, especially in riverbeds and gravel areas.

When looking for Chalcedony, search for stones with a shiny, see-through look. They can be white, gray, or blue. A shovel and a sieve can help you find them in gravel or riverbeds. If you’ve found one, gently wash it to see its true color.

People believe Chalcedony can help with communication and clear thinking. It’s a stone that many feel brings peace and understanding.

Fossilized Coral

In Iowa, you can find old Coral turned into stone, especially in the northeast. Places around Coralville are especially good because of the limestone quarries there.

Look for stones with patterns that remind you of honeycombs or tree branches. These patterns show where Coral used to be. A small hammer and chisel can help you get these Fossils out of the limestone. Be gentle so you don’t break them.

Some people believe that Fossilized Coral has the energy of the ancient sea. It’s thought to help with change and keep you grounded.

Lake Superior Agates

Lake Superior Agates are colorful stones mainly found in Minnesota, but you can also find them in Northern Iowa, near rivers and old glacier spots.

These stones have bright red, orange, and yellow lines. A sieve and shovel can help you find them. When you think you’ve found one, wash it to see its bright colors.

People believe these stones give strength and stability. They’re often used to stimulate creativity and aid in turning ideas into reality.

Quartz 

Quartz Crystals are popular in Iowa, especially for those who know where to look. These clear stones are scattered throughout the state, but some of the best spots to hunt for them are in the northeastern region. 

Areas around the Cedar and Iowa Rivers are known to be rich in Quartz-family minerals. Regions around Muscatine are another hotspot where Quartz and other gemstones can be found in abundance.

When searching for Quartz in Iowa, keep an eye out for clear or slightly cloudy stones with a distinct shape. These crystals often stand out against river gravels and rocky outcrops. If you plan to dig, a small pick and shovel will be your best friends. Once you spot a potential Quartz crystal, it’s a good idea to wash it off to reveal its clarity and beauty.

Some say Quartz can help with relaxation, healing, and spiritual growth. Whether you believe in its metaphysical properties or just appreciate its natural beauty, finding a Quartz crystal in the wild is always a rewarding experience.

Black Calcite 

Exploring Bells Mill Park in Iowa, you might stumble upon a rare find – Black Calcite, a unique discovery within the state. These crystals are dark and shiny and can be found in rocky areas. 

To dig them up, you only need some basic tools – a pick and a shovel. When handling these crystals, be gentle to prevent any damage.

Many people believe it can help you feel more grounded and centered, like finding your balance. It’s also thought to improve your memory and bring a sense of calm to your mind. 

Gem-Quality Colored Chert

Gem-quality colored Chert is another gemstone that rockhounds can find in Iowa. Mount Pleasant is a notable location where this type of Chert can be discovered.

Chert is typically opaque and can vary in color. Having a geologist’s hammer and chisel is beneficial when hunting for Chert. If you come across a potential piece of Chert, gently chip away the surrounding rock to extract it.

Chert has been used for millennia to make tools due to its sharp edges when broken. Spiritually, it’s believed to help with achieving stability and grounding.

Coldwater Agate

Coldwater Agates, a distinctive type of Agate, is a remarkable discovery within Iowa. These unique gems can be found in specific areas, with Bremer and Benton Counties being renowned for their presence.

Regarding Coldwater Agates, their hallmark feature is their striking bands of colors that vary from one Agate to another. 

To hunt for these captivating gemstones, carry a small pick and a bucket. Once you spot a potential Agate, a simple rinse with water can reveal its intricate patterns, making the discovery even more rewarding.

These Agates boost your mental abilities and help you concentrate better. In the world of natural treasures, Agates stand out as both aesthetically pleasing and potentially beneficial to your overall well-being.

In Iowa, Petrified Wood can be found in various locations. One notable spot is near Orient, specifically about 5 miles to the northeast. Along with Petrified Wood, you can also discover Agate and Quartz crystals there.

When searching for Petrified Wood, look for wood-like structures that have turned to stone over time. A good shovel and pick will be handy when digging in rocky terrains. Once you find a piece, cleaning it gently to reveal its intricate patterns and details is essential.

Petrified Wood is believed to be a grounding stone, offering stability and strength. Many also consider it a stone of transformation, helping individuals grow spiritually and emotionally.

Freshwater Pearls

Freshwater Pearls, an exquisite find in Iowa, are not from the sea but harvested from mussels in the Mississippi River, mainly in the Muscatine area. These pearls come in shades, including pink, gold, and red; some are even considered gem-quality.

When searching for these unique Pearls, search within mussels dwelling in sandy parts of the river. A simple clam knife can help you open the mussels and reveal the hidden Pearls. Once you uncover a Pearl, it’s essential to handle it gently to prevent any scratches or damage.

Pearls are often associated with qualities like purity, innocence, and integrity. Many people believe wearing them can bring a sense of calmness, help balance one’s karma (the idea of cause and effect in life), and strengthen relationships.

Jasper

Jasper is an intriguing gemstone you can uncover in various parts of Iowa. If you’re eager to find this special stone, explore places like Dubuque, where it often hides in the gravel along the rivers. In Emmetsburg and Graettinger, you can discover streams and gravels that frequently contain Jasper.

To identify Jasper, look for its unique patterns and colors. You’ll want a sturdy shovel and a pick to help you dig in gravel-rich areas. When you come across a potential piece, pick it up and examine it closely to confirm its characteristic patterns.

Beyond its aesthetic charm, Jasper is believed by many to possess unique attributes. It’s frequently linked to grounding energies, offering protection, and fostering stability. 

Keeping Jasper nearby is believed to bring comfort and alleviate fears, rendering it a captivating find and a potential wellspring of well-being within Iowa’s natural surroundings.

When looking for Chert, it’s essential to be cautious, as the stone often blends in with its surroundings, so a keen eye is crucial. Like most rockhounding adventures, a good shovel and pick will aid your search. If you come across a piece, take a moment to examine its texture and color.

Beyond its physical attributes, Chert is believed to have metaphysical properties. It’s thought to help with memory enhancement and is often used in meditation practices for grounding.

Limonite

Iowa holds a hidden treasure in the form of Limonite, a mineral you can discover, especially in the northeastern region. Clayton County, in particular, is a known hotspot where collectors might find this mineral. 

This county’s quarries and mining dumps have often yielded Limonite specimens and other minerals, like Pyrite and Sphalerite.

When seeking Limonite, it’s crucial to recognize its unique yellow-brown color, which can sometimes resemble rust. You’ll want to have a sturdy shovel and pickaxe to explore rocky terrains. Upon spotting a potential piece of Limonite, a gentle cleaning can reveal its true color and texture.
