Wisconsin’s glacial history didn’t just shape its landscape – it also left behind some amazing mineral deposits. Among them is beryl, a gorgeous crystal that comes in various colors, from deep blue to soft green.

Many rockhounds spend weeks or months trying to track down good beryl spots in Wisconsin. We’ve been there too, and we know how frustrating it can be to waste time at spots that don’t deliver.

That’s why we put together this list of proven beryl locations across the state. These spots have consistently produced good finds, and we’ve double-checked each one with local collectors and geological reports.

Skip the trial and error – we’ll show you exactly where to look.

How Beryl Forms Here

Beryl forms in specific geological environments, primarily in pegmatites and hydrothermal veins. These locations provide the right conditions for crystallization.

The process begins deep within the Earth, where hot, mineral-rich fluids carry essential elements like beryllium, aluminum, and silicon. As these fluids move through cracks in the rocks, they cool down, allowing beryl to crystallize slowly over time.

The unique hexagonal crystal structure of beryl arises from chains of silicate tetrahedra that link together. This structure not only gives beryl its strength but also its beautiful colors, which can vary based on impurities present during formation.

Thus, the intricate dance of temperature, pressure, and mineral content creates this stunning gemstone.

Types of Beryl

Beryl comes in a stunning variety of colors and formations, each with its own unique characteristics and value in the gemstone market.

Aquamarine

Aquamarine’s sea-blue to blue-green colors instantly remind people of ocean waters. The stone ranges from pale, almost colorless shades to deep teal hues, with the most valued pieces showing a bright sky-blue color. Iron gives aquamarine its signature color, and most pieces are remarkably clear.

The stone’s exceptional clarity makes it stand out. While other similar stones often have visible flaws inside, aquamarine typically appears clean and transparent. This clarity allows light to pass through beautifully, creating bright sparkles and flashes.

Ancient civilizations treasured aquamarine, using it in decorative pieces and protective items as far back as 500 B.C. The stone’s enduring popularity speaks to its timeless appeal.

The largest cut aquamarine, the Don Pedro, weighs an impressive 10,363 carats and sits in the Smithsonian Institution.

Maxixe

Maxixe showcases an intense blue to violet-blue color that makes it truly distinctive. However, its most fascinating feature is how its color changes when exposed to light or heat, sometimes shifting to a brown-yellow shade.

The stone’s color comes from natural radiation effects, creating a unique appearance that sets it apart. When viewed from different angles, Maxixe shows varying shades of blue, an optical effect that makes each piece special.

One of Maxixe’s most intriguing aspects is its color stability. The vibrant blue can fade with exposure to sunlight, but interestingly, artificial radiation can restore its original color. This unique characteristic has made it a subject of scientific study.

Bixbite

Bixbite displays a striking red color that ranges from soft pink-red to deep, rich red tones. The vibrant color comes from manganese in its structure, creating a remarkable appearance that catches the eye immediately.

Its formation process makes it extraordinarily special. The specific conditions needed for Bixbite to form rarely occur in nature, contributing to its exceptional rarity. For perspective, one Bixbite crystal is found for every 150,000 gem-quality diamonds.

Most Bixbite pieces are small, usually under one carat, making larger specimens particularly remarkable. The stone’s intense color combined with its small size creates concentrated beauty that collectors particularly appreciate.

Originally discovered in 1904 by Maynard Bixby, this stone was first mistaken for red emerald. Its discovery sparked significant interest in the geological community, and it continues to captivate collectors and enthusiasts with its remarkable combination of color and rarity.

Emerald

Emeralds are recognized for their vivid green color, which can range from yellow-green to deep jade. The most desirable shades are bluish-green with even saturation and medium to medium-dark tones. This distinctive green comes from traces of chromium and vanadium in the stone.

Almost every natural emerald contains internal marks called “jardin” (meaning garden in French). These natural patterns make each stone unique. While other gems are valued for being completely clear, these garden-like patterns are actually appreciated in emeralds.

Ancient Egyptians prized emeralds above all other gems. The Duke of Devonshire Emerald, weighing 1,383.93 carats, remains one of the largest uncut emeralds ever found. The stone’s rarity also adds to its appeal – emeralds are actually rarer than diamonds.

Golden Beryl

Golden Beryl shines with bright yellow to rich golden colors that seem to glow from within. The color comes from tiny amounts of iron in the stone. Most pieces are beautifully clear, without the internal marks often seen in other similar stones.

The stone’s exceptional clarity makes it special. Light passes through easily, creating bright sparkles that enhance its natural golden glow. This clarity, combined with its color, creates an impressive display of brilliance.

Large crystals of Golden Beryl are particularly impressive. They form in six-sided shapes and can grow to remarkable sizes while maintaining their beautiful transparency. This makes each piece uniquely striking.

Heliodor usually presents a yellow-green or greenish-yellow hue. In contrast, Golden Beryl is characterized by its pure golden yellow or bright yellow appearance.

Heliodor

Heliodor captures the essence of sunlight with its yellow to golden-yellow colors. Some stones show hints of green, creating unique color combinations that set them apart from other yellow gems. The name itself means “gift of the sun” in Greek.

These stones typically form as clear, transparent crystals. They often show interesting natural etchings on their surface, adding character to each piece. The clarity of Heliodor allows light to pass through beautifully, creating bright flashes of color.

The stone’s surface patterns make each piece distinct. Natural markings and crystal shapes create interesting features that collectors appreciate. These characteristics tell the story of how the stone formed.

High-quality Heliodor pieces are quite rare. When found, they often show remarkable size and clarity together. This combination of qualities makes each good specimen special and worthy of any rock collection.

Goshenite

Goshenite stands out with its pure, colorless appearance. The stone is remarkably clear and transparent, often resembling a drop of pure water. This clarity comes from its formation in environments free from color-causing elements.

Many people appreciate Goshenite for its excellent transparency. The stone rarely contains internal marks or cloudiness. This makes it particularly brilliant when cut, allowing light to pass through cleanly and create bright sparkles.

One fascinating aspect of Goshenite’s history is its use in early optical instruments. During medieval times, people crafted these clear crystals into lenses for spectacles and magnifying glasses. This happened before modern glass-making techniques existed.

The stone’s purity makes it special in collections. While other similar stones show various colors, Goshenite maintains its water-clear appearance. Large, clear crystals are particularly prized among collectors who appreciate their pristine beauty.

Green Beryl

Green Beryl shows soft to vibrant green shades, from pale mint to deeper forest tones. The color comes from tiny amounts of iron in the crystal. These stones typically have excellent clarity with few internal marks.

The stone’s color can change slightly under different lights. Some pieces show a hint of yellow when viewed from certain angles. This subtle color play adds to their appeal and makes each stone unique.

Most Green Beryl crystals form with remarkable clarity. They often grow into large, clear pieces that maintain their beautiful transparency. This makes them particularly impressive in collections.

These stones often develop in larger sizes than similar green gems. Their natural crystal shape is six-sided, and they can grow quite large while staying clear and bright. This combination of size and clarity makes them special.

Morganite

Morganite displays delicate pink to peach colors that range from soft pastels to deeper salmon tones. The beautiful color comes from manganese in the crystal structure. Some stones show different shades of pink when viewed from different angles.

These crystals can grow to impressive sizes. Some of the largest pieces have weighed over 20 pounds. The size potential makes Morganite particularly interesting for collectors and specimen hunters.

The stone often forms with remarkable clarity. Most pieces are free from internal marks, allowing light to pass through beautifully. This clarity enhances their soft, romantic colors.

Morganite’s colors tend to be subtle and sophisticated. The gentle pink and peach tones set it apart from more intensely colored stones. Large, clear pieces with good color are especially valued in collections.

What Rough Beryl Looks Like

Identifying a rough beryl might seem tricky, but with a few tips, you can spot one even if you’re not a rock expert. Here’s how you can do it.

Look for the Hexagonal Crystal Structure

Raw beryl typically forms in six-sided (hexagonal) crystals, sometimes as long columns. You’ll often spot these distinct shapes even in rough specimens.

They’re not always perfect – sometimes they’re broken or embedded in other rocks. But if you see a hexagonal pattern, especially in a greenish or bluish stone, you might have beryl on your hands.

Check for a Glassy or Waxy Luster

Unlike quartz’s brilliant shine, beryl has a more subdued glassy look. Run your finger across it – it should feel smooth but not super shiny.

Sometimes it’s even a bit waxy, like a candle that’s cooled down. If it’s too sparkly or looks metallic, probably not beryl.

Assess the Color Range

Beryl’s pretty sneaky with its colors. Most rough pieces come in pale green but don’t just stop there. Look for subtle blue tints, yellowish hues, or even colorless specimens.

The color’s usually uneven – you might see darker and lighter patches in the same piece. Grab a flashlight and shine it through thinner edges – beryl often shows some transparency.

Test the Hardness

Here’s a neat trick: try scratching the surface with a steel nail. Beryl’s pretty tough (7.5-8 on the Mohs scale) and won’t scratch easily.

Got a piece of quartz handy? Beryl should be able to scratch it. But be gentle – you’re not trying to destroy the specimen!

Tips on Where to Look

Once you get to the places we have listed below there are some things you should keep in mind when you’re searching:

Pegmatite Formations

Look in coarse-grained igneous rocks called pegmatites. These form as magma cools slowly underground. Beryl crystals here are often large and well-formed.

Check exposed pegmatite veins on hillsides or road cuts where erosion has revealed the rock layers.

Old Mining Areas

Explore abandoned mica and feldspar quarries. Beryl often occurs alongside these minerals. Scout the dump piles and tailings, where miners discarded “worthless” rocks.

These areas frequently contain overlooked beryl specimens that weren’t considered commercially viable during active mining periods but are perfect for collectors.

Stream Beds

Search gravel beds in streams that cut through metamorphic rock areas. While most people focus on looking directly in the water, the real treasures often hide in the gravel deposits along the banks where heavier minerals, including beryl fragments, tend to accumulate during seasonal flooding and natural sorting processes.

Granite Outcrops

Check weathered granite outcrops, especially where the rock shows signs of mineralization. Look for zones with white quartz and mica, as beryl commonly associates with these minerals. Focus on areas where the granite appears altered or shows color variations.

The types of Beryl you can find around the state

The types of beryl mostly found in Wisconsin are Aquamarine and Morganite. Aquamarine, known for its beautiful blue color reminiscent of seawater, is commonly found in large crystals within granite pegmatites across various counties in the state.

Morganite, which exhibits a pink to peach hue, has also been reported in Wisconsin. This variety is less common than aquamarine but is appreciated for its delicate color and is often used in jewelry.

Both types of beryl contribute to the state’s mineral diversity and appeal to gem enthusiasts and collectors alike.

Some Great Places To Start

Here are some of the better places to start looking for beryl in Wisconsin:

Embarrass River

The Embarrass River flows for 62 miles through Shawano County, Wisconsin. It’s a tributary of the Wolf River and runs past the small village of Tigerton. The river splits into three branches – North, Middle, and South – with the South Branch starting near Eland.

The best spot to find Beryl is about 2 miles east of Tigerton, just south of the Tigerton Dells. This area has plenty of quartz and potassium feldspar, which often occur alongside beryl.

The South Branch area is particularly good for searching because it has more exposed rock formations along its banks.

The spot is popular among local rockhounds who also find other interesting minerals while searching for beryl.

Beilke Quarry

Beilke Quarry sits in Marathon County, near Wausau in north-central Wisconsin. It’s part of the Nine Mile Pluton, an area known for its rich mineral deposits. The quarry features unique “rotten granite”.

When searching for beryl here, look for the lighter-colored pegmatite veins in the granite. The crystals often form in these veins, and the weathered “rotten” state of the granite makes them easier to spot and extract.

The quarry’s beryl crystals can range from small specimens to larger pieces, and they sometimes show the classic hexagonal shape that beryl is known for.

The quarry is also home to other interesting minerals like feldspar and quartz, making each visit a chance to find various specimens.

Pine River

The Pine River area in Florence County, Wisconsin, stretches along an 80-mile river that flows into the Menominee River. The area’s pegmatites, formed from ancient granite rocks, create perfect conditions for beryl formation.

Yellow beryl crystals have been found here in pegmatite float boulders. These crystals often appear near Section 22 T.39N. R.17E, north of Fern.

The Pine River Quartzite Conglomerate, exposed near the Pine River Reservoir, makes this spot special for rockhounds.

Besides beryl, you can find other interesting minerals like quartz, spodumene, and elbaite. The best places to look are around the river gravels and exposed rock formations near the reservoir.

Eau Claire River

The Eau Claire River flows through northwestern Wisconsin, creating a stunning rocky gorge called the Dells of the Eau Claire River. This river runs near the city of Eau Claire and is known for its unique tilted bedrock formations.

The river area holds some of Wisconsin’s oldest rocks from the Precambrian period. At Big Falls County Park, you can see exposed gneiss, amphibolites, and schists that tell the story of the area’s rich geological past.

The Little Falls area of the river is special for beryl hunting. Large beryl crystals have been found here in micaceous pegmatite rocks. These crystals form in light-colored, coarse-grained rocks that stand out from the darker surrounding stone.

Farr Lake

Farr Lake is a small 12-acre lake in Oconto County, Wisconsin, close to the town of Mountain. The most promising spots for finding Beryl are in the pegmatite outcrops southeast of the lake.

The lake’s geology is part of the Lower North Branch Oconto River Watershed. While the lake bottom is mostly muck, the surrounding rocky areas are what interest gem hunters.

The best places to look are along exposed rock outcrops and stream beds near the lake. Many rockhounds have success searching along County Road Q and WI 64 W, where pegmatite formations are more visible.
