While Ohio isn’t known for turquoise deposits like Arizona or New Mexico, rock collectors here have found some amazing mineral specimens over the years.

If you’re looking to find turquoise in Ohio, you’ll need to know exactly where to look. Many beginners waste time searching in the wrong spots, often coming home empty-handed and frustrated.

We’ve done the hard work for you by talking to local collectors and geology experts. After months of research, we’ve put together a list of the most promising locations where you might find turquoise in Ohio.

How Turquoise Forms Here

Turquoise forms through a unique process involving water and minerals. It begins when acidic water seeps into the ground, moving through rocks that contain copper and aluminum.

As this water interacts with these minerals, it breaks them down and allows the copper and aluminum to combine with phosphorus, creating turquoise.

This usually happens in shallow areas, often less than 20 meters deep, where the environmental conditions are just right. 

This mineral typically fills cracks and cavities in rocks, often in dry, desert-like areas. The presence of iron can also influence its color, giving it beautiful shades of blue and green.

Over time, the turquoise hardens, resulting in the stunning gem we see today, prized for its vibrant hues and unique patterns.

The Types Of Turquoise Found in the US

Turquoise comes in a variety of stunning types, found in the US as well as in our state. Here are the types of turquoise found in the US:

Kingman Turquoise

Kingman Turquoise showcases a vibrant range of colors from pale green to deep “high blue.” Its matrix patterns can include white, light brown, or black veining, setting it apart from other turquoise types.

This stone is often stabilized to enhance its durability and color, allowing for broader use in jewelry making. The natural Kingman turquoise typically presents a medium blue hue with a water web matrix.

Kingman Turquoise is recognized as one of the most sought-after American turquoise. Its consistent supply has made it a staple in Native American jewelry and artisan crafts, contributing to its ongoing popularity.

Carico Lake Turquoise

Carico Lake Turquoise is known for its clear robin’s egg blue to vibrant lime green colors. It often features a unique spider-web matrix in brown or, more rarely, black, adding texture and shine to the stone.

What makes this stone special is its high zinc concentration, which gives it an electric lime-green hue. This color is both rare and desirable among turquoise varieties.

Gem-quality Carico Lake Turquoise is scarce, making up less than 3% of the mine’s annual output. This rarity, combined with its natural beauty, makes it a prized item for collectors and enthusiasts alike.

Lone Mountain Turquoise

Lone Mountain Turquoise is known for its bright blue to deep green colors, often featuring intricate spider web matrix patterns. These fine lines create a web-like design, enhancing its visual appeal.

This stone stands out for its exceptional hardness and color retention. It maintains its vibrant hue over time, a quality not common in all turquoise varieties.

Lone Mountain Turquoise is highly valued in the collector’s market, second only to Lander Blue Turquoise. Its ability to produce high-quality spider web turquoise makes it a favorite among jewelry artisans and collectors.

Morenci Turquoise

Morenci Turquoise stands out with its deep blue color, a result of its high copper content.

Its most striking feature is the iron pyrite matrix, which gives it a metallic shimmer when polished. Some pieces also show a water web matrix, creating dark blue webbing patterns.

This stone is no longer mined, making it rare and highly collectible. All available Morenci Turquoise comes from mining operations that stopped in 1984.

High-grade pieces, known for vibrant blues and pyrite matrix, make up less than 10% of the total yield.

Pilot Mountain Turquoise

Pilot Mountain Turquoise catches the eye with its bright to dark blue hues, often showing a greenish tint.

What makes it special is its brownish-red limonite matrix, creating beautiful mottled patterns. The stone forms in hard veins, thin seams, or nuggets.

This turquoise has an interesting history, first mined around 1930. It’s known for its limited availability, with only 150 to 200 pounds of rough stone extracted twice a year. This scarcity adds to its appeal.

The unique mottled patterns of the limonite matrix make Pilot Mountain Turquoise a favorite for decorative pieces and jewelry.

Sleeping Beauty Turquoise

Sleeping Beauty Turquoise is famous for its vivid sky-blue color. Unlike many other turquoise types, it has little to no veining or matrix, giving it a pure, consistent look. The color can range from light robin’s egg blue to deeper sky blue.

This stone is naturally hard, which means it doesn’t need stabilization for use in jewelry. This quality makes it popular with jewelers. The Sleeping Beauty mine closed in 2012, making the stone rarer and more valuable.

Sleeping Beauty Turquoise became a hit in the 1970s and 80s, used in both Native American jewelry and mainstream fashion. Its consistent quality and vibrant color have made it a standard in Southwestern jewelry.

Bisbee Turquoise

Bisbee Turquoise stands out with its vibrant blue shades, ranging from deep indigo to light robin’s egg blue. Green hues are less common but still occur.

Its distinctive matrix often displays a striking spiderweb pattern against a reddish-brown backdrop.

This stone’s unique appearance comes from its host rock color and gloss. Unlike some turquoise with metallic matrices, Bisbee’s matrix is typically more earthy and varied in color.

Bisbee Turquoise is highly valued for its quality and rarity. Its historical significance, being one of the oldest turquoise sources in North America, adds to its appeal among collectors and enthusiasts.

Royston Turquoise

Royston Turquoise is a gem of many faces. Its colors can shift dramatically, even within a single stone.

You might find a piece that starts as a soft blue and gradually transforms into a rich green. This color play is a hallmark of Royston Turquoise.

The stone’s matrix is equally fascinating. The matrix can create intricate landscapes within the turquoise, resembling golden sunsets or stormy skies.

Royston Turquoise is also known for its ability to take an exceptionally high polish. This quality, combined with its natural hardness, makes it a favorite for jewelry that can withstand daily wear.

Dry Creek Turquoise

Dry Creek Turquoise stands out with its pale pastel blue color, similar to Larimar. It often has light brown, golden yellow, or orange webbed matrices, adding to its beauty.

Unlike many turquoise types, it’s naturally hard and takes a stunning polish without treatment.

This stone is quite rare. It was discovered in the 1990s in an area with low levels of heavy metals. These metals usually give turquoise its bright colors. The unique geological setting results in Dry Creek’s captivating pale blue hue.

The natural hardness and ability to take a high polish make Dry Creek Turquoise special.

Ithaca Peak Turquoise

Ithaca Peak Turquoise is known for its stunning range of blues. It can be light blue with black spider-webbing or deep rich blue with black matrix.

Some pieces even have quartz matrix and pyrite inclusions. The most valued stones have vibrant to dark blues with good pyrite inclusions.

What makes this stone unique is its pyrite. In Ithaca Peak Turquoise, the pyrite often has a brassy color. This helps tell it apart from similar stones like Morenci turquoise.

Recently mined Ithaca Peak Turquoise looks different from older pieces. The new stones are lighter blue to green and usually don’t have a webbed matrix. This change in appearance over time adds to the stone’s interesting history.

What Raw Turquoise Looks Like

When you’re going to collect the raw turquoise, it’s important to know what to look for. Here are some tips to help you identify genuine raw turquoise:

Look for the Blue-Green Color

The color is the big clue. Rough turquoise is often blue or green, sometimes with hints of both.

The blue comes from copper, while the green hints at more iron or other minerals.

Real turquoise tends to have a more vibrant, consistent color. If it looks too perfect, like solid blue or green with no variations, be cautious. Nature isn’t that perfect!

Assess the Density and Weight

Pick up the stone and feel its weight. Real turquoise is pretty dense, so it feels heavier than it looks. If the stone feels too light, it might not be genuine.

Authentic turquoise has a specific gravity of about 2.5 to 2.9, making it heavier than many imitations.

The density comes from the minerals packed tightly together over millions of years. A heavier stone usually means a better-quality piece.

Check for a Glassy or Waxy Luster

Rough turquoise often has a glassy or waxy luster, not too shiny but not dull either. When you hold it up to the light, the surface might have a soft, smooth sheen. This luster is key.

A rough piece with a good luster usually indicates that it’s real turquoise and not a fake. You’ll notice that it reflects light in a muted way, not too bright.

Consider the Stone’s Shape and Texture

Rough turquoise isn’t always smooth. It often has a bumpy, uneven texture because it forms in cracks and crevices of other rocks.

The stone’s shape might be irregular or lumpy. This natural texture is a telltale sign that you’re holding real turquoise and not a polished or treated piece.

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:

Riverbeds

Look for turquoise in riverbeds. Over time, water flow can expose hidden stones.

Sediment may hold the gems you’re after. Be prepared to dig through gravel and dirt to find them.

Abandoned Mines

Old mines can be treasure troves for turquoise. These sites often have loose rocks where turquoise might be hiding.

Always be careful while exploring abandoned areas, though.

Hillsides

Check hillsides, especially where erosion is visible. Rain and wind can uncover layers of earth, exposing turquoise.

It’s a bit of a hunt, but it can be rewarding. Sometimes, you’ll find small stones just lying on the surface.

Rocky Outcrops

Rocky outcrops are great places to search. They are full of minerals and might have turquoise.

Explore the cracks and crevices. Turquoise often hides in these tight spaces.

Some Great Places To Start

Here are some of the better places to start looking for Turquoise in Ohio:

Flint Ridge

Flint Ridge spans ten miles across eastern Licking County and western Muskingum County in Ohio. The 533-acre Flint Ridge Ancient Quarries & Nature Preserve protects this area where Native Americans mined flint for thousands of years.

The ridge formed about 300 million years ago when this area was under a shallow ocean. The site is most famous for its rainbow-colored flint, which comes in shades of red, blue, green, and white.

Today, you can explore the old quarry pits while hiking the preserve’s trails. The best places to look for turquoise and other rocks are in areas where erosion has exposed the bedrock.

While mainly known for flint, the area’s unique geology also makes it interesting for finding other minerals in the exposed rock layers.Seneca Caverns

Seneca Caverns

Seneca Caverns sits in northeastern Seneca County, Ohio, just outside the small town of Flat Rock. The caverns formed millions of years ago from Columbus Limestone and Lucas Dolomite.

The cave system drops seven levels deep, reaching 110 feet underground. A clear underground stream called Ole Mist’ry River flows through the bottom level.

The Chestnut Room, stretching 250 feet, is the biggest room in the caverns and shows off amazing rock formations.

While looking for turquoise, the Fossil Room (30 feet down) and Chert Alley (55 feet down) are great spots to explore. The cave walls show interesting patterns from years of water flow, making it easier to spot mineral deposits.

Hocking Hills State Park

Hocking Hills State Park sits in southeast Ohio near Logan, about an hour from Columbus. This 2,000-acre park features deep caves, waterfalls, and towering cliffs that make it one of Ohio’s most visited natural areas.

While looking for turquoise, focus on the areas around Old Man’s Cave and Cedar Falls. These spots have exposed rock layers where minerals often collect. The natural hollows and rock shelters throughout the park are good places to search too.

Besides possible turquoise, visitors often find quartz crystals and interesting pieces of sandstone with unique patterns.

The park has over 25 miles of hiking trails that take you past rock formations and waterfalls. Rock Bridge Trail and Hemlock Bridge Trail are great spots to start your search.

Lake Erie Shoreline

The Lake Erie Shoreline runs along Ohio’s northern edge, spanning several counties like Lorain, Cuyahoga, and Ashtabula. This stretch of land meets one of North America’s Great Lakes and has some interesting rocks and minerals.

One cool thing about this shoreline is its beach ridges. These old beaches are now found miles away from the current lake, showing where Lake Erie’s water level used to be long ago. The area also has big sandstone quarries in Amherst and salt mines in Cuyahoga County.

Rock collectors often visit the beaches after storms when waves wash up different kinds of stones.

While searching turquoise, you might find limestone, gypsum, and various other minerals in the beach deposits and along cliff areas. The best spots are usually near the natural rock outcrops and along the wave-washed shore.
