West Virginia isn’t usually the first place thought of for gemstone hunting, but it’s a great state for finding peridot. From famous spots like Seneca Rocks to secret locations near the New River Gorge, there are plenty of chances to discover these bright green treasures.

Exploring areas like the Monongahela National Forest or searching near creeks in Hampshire County makes the hunt even more exciting. With the right spots in mind, finding peridot becomes a fun adventure surrounded by the state’s beautiful mountains and rivers.

How Peridot Forms Here

Peridot forms deep within Earth’s mantle, around 20 to 55 miles below the surface, where intense heat and pressure create the perfect conditions. It’s actually made from magma that cools super slowly, letting the crystals grow nice and big.

The main ingredient is olivine, which needs temperatures between 1,000°C to 1,300°C to form properly. When volcanoes erupt, they sometimes bring these green gems up with them in basalt rocks.

What’s really cool is that peridot can also come from meteorites – yep, some of these crystals literally fell from space! The iron and magnesium inside the stone is what gives it that signature olive-green color.

Types of Peridot

Peridot’s value fluctuates based on its origin and quality, with its vivid colors making it a distinctive and sought-after gemstone. Here are the different types of Peridot:

Burmese Peridot

Burmese Peridot shows off a pure, bright green color that looks almost like spring leaves. Most other peridots have brown or yellow mixed in, but Burmese ones usually don’t.

The stone’s special green color comes from the iron inside the crystal. When light hits it, the stone seems to glow from within, creating a beautiful effect that catches everyone’s eye.

These stones often have special markings inside called “lily pads.” These are small, round patterns that look like tiny circles when you look at them with a magnifying glass.

You can often find Burmese Peridot in larger sizes, which makes them great for bigger jewelry pieces. The stones keep their bright color even under different kinds of lighting, so they look good both in sunlight and indoor light.

Pakistani Peridot

Pakistani Peridot is known for its vibrant green hues, which can range from yellow-green to olive green. The stones are usually very clear and shine beautifully when light hits them.

The stone typically has a vitreous luster and can be quite transparent, showcasing its brilliance. High-quality specimens can exhibit exceptional clarity with minimal inclusions, which enhances their appeal in jewelry.

Inside these stones, you might find tiny bubbles of liquid and gas. These create interesting patterns that make each stone has its unique pattern of these markings.

These peridots often come in larger sizes and maintain their bright color even under artificial light. This makes them look just as good in the evening as they do during the day, which is why some people call them “evening emeralds.”

Arizona Peridot

Arizona Peridot shows off a bright, lime-green color that sometimes has olive tones. The stones are usually smaller than other peridots but make up for it with their exceptional brightness and sparkle.

These stones often have a special kind of clarity that makes them appear very clean to the naked eye. When you look at them closely, you might see tiny specks of black minerals inside, which are typical of Arizona stones.

Arizona Peridot is especially famous due to its association with the San Carlos Apache Reservation, which is one of the largest sources of peridot in the world. The region’s peridot is highly valued not only locally but also within the broader gemstone market for its quality and vibrant color.

Changbai Peridot

Changbai Peridot displays a deep, rich green color that sets it apart. Their color is more intense than other peridots, showing deep forest green tones.

These stones usually come in medium sizes, around one carat. What makes them special is how clean they look – most have very few internal marks or inclusions. This clarity lets more light pass through, making them especially bright and sparkly.

The color of Changbai Peridot stays consistent throughout the stone. Unlike some other peridots that might show patches of different colors, these maintain their rich green tone evenly. This makes them particularly appealing when set in jewelry.

Their superior clarity and rich color have made them increasingly popular since 2005. Even though they’re newer to the market compared to other peridots, they’ve quickly gained recognition for their outstanding quality.

Vietnam Peridot

Vietnam Peridot, also known as chrysolite, has a special yellowish-green color that makes it easy to spot. They often come in larger sizes than peridots from other places.

When light passes through these stones, it creates a unique double-image effect. If you look closely at a faceted stone, you might see the edges appear doubled. This effect makes them sparkle in a special way.

Vietnamese peridot is often found in mafic and ultramafic rocks, which are rich in iron and magnesium, leading to the formation of larger and higher-quality stones.

The green color stays even throughout the whole stone. This consistent color is one reason why collectors really like Vietnam Peridot.

Norway Peridot

Norway Peridot comes in beautiful olive green shades. The color can range from light yellow-green to deep olive. The amount of iron inside the stone decides how dark or light the green will be.

When light enters these stones, it splits into two beams. This makes the stone look extra sparkly and bright, even when the light isn’t very strong. You can see this special effect best in well-cut stones.

Norway Peridot is part of a long tradition of peridot use in jewelry and artifacts, including significant pieces like those found in the Shrine of the Three Kings in Cologne Cathedral, which were initially thought to be emeralds but were later identified as large peridots.

Pallasite Peridot

Pallasite Peridot comes from space! These green crystals are found inside meteorites, mixed with metal from space. The green crystals stand out beautifully against the silvery-gray metal background.

These stones form a natural pattern in the meteorite. The mix of bright green crystals and shiny metal creates a beautiful design that looks like stained glass when light shines through it.

Scientists find these stones especially interesting because they tell us about how planets form. The mix of metal and crystal shows us what the inside of planets might look like.

These stones are pretty rare since they only come from meteorites. Collectors really like them because each piece tells a story about space and has its own unique pattern of green crystals.

Antarctica Peridot

Antarctica Peridot usually comes in smaller sizes, but each stone packs a lot of sparkle. They show a pure green color that can look slightly yellowish or olive in different lights.

These stones formed under extreme cold conditions, which affects how they look. They tend to be very clear with few internal markings. Most pieces are under two carats in size.

The extreme conditions where these stones formed make them special. They had to survive intense pressure and cold temperatures to reach the surface.

These stones are among the rarest peridots because they’re so hard to find. Their small size actually helps them sparkle more intensely than larger stones.

Hawaii Peridot

Hawaii Peridot has a rich olive-green color. Inside many stones, you can find special bubble-shaped marks called “lily pads.” These marks look like tiny round discs frozen in the stone.

One cool thing about these stones is that some of them contain tiny bits of gas trapped inside from when they formed. Scientists can study these bubbles to learn about conditions deep in the Earth.

In Hawaiian culture, peridot is associated with Pele, the goddess of fire and volcanoes, which adds to its allure among collectors interested in cultural artifacts.

New Mexico Peridot

New Mexico peridot typically ranges in color from brown and greenish-brown to yellowish-green and the more desirable green hue. This variety stands out due to its potential for a wider color range compared to peridot from other regions.

One notable aspect of New Mexico peridot is its occurrence in volcanic debris from ancient eruptions, specifically from a 180,000-year-old volcano. This geological background contributes to the unique properties of the stones found there.

The Kilbourne Hole area is particularly noted for producing high-quality peridot that is sometimes considered superior to that from Arizona.

What Rough Peridot Look Like?

Peridot has several distinctive characteristics that can help you identify it in its natural form. Here are the key features to look for:

Check for a glassy or waxy luster

Raw peridot typically shows a distinct glassy to waxy shine, even in its unpolished state. When you shine a light on it, you’ll notice it’s not quite as sparkly as quartz but definitely shinier than most common rocks.

Pro tip: if it looks kind of like olive oil frozen in stone form, you might be onto something!

Look for that signature olive-green color

Unlike other green stones, peridot has this unique yellowish-green to olive-green color that’s pretty consistent throughout the stone.

Here’s the thing – even when rough, it shouldn’t have dark spots or zones. If you spot patches of brown or black, you’re probably looking at something else.

Hold it up to natural light – a genuine peridot will show that characteristic color even in its rough form.

Examine the crystal structure

In its natural state, peridot forms stubby, prismatic crystals. Look for somewhat rectangular or barrel-shaped formations – they might be rough, but you should see hints of this shape.

Sometimes you’ll spot these crystals embedded in darker volcanic rock (that’s basalt, by the way). The surfaces might look a bit pitted or weathered, but they shouldn’t be perfectly smooth.

Tips on Where to Look

Peridot typically forms in volcanic areas and can be found in several accessible locations. Here’s where you should start looking:

Volcanic Rock Formations

Look for dark-colored basalt rocks and olivine-rich formations. Check areas where ancient lava flows have created large rock deposits, especially those with visible green crystals embedded in the rock. These rocks often weather over time, exposing the peridot crystals.

Stream Beds and Gravel Banks

Search in stream beds where water has naturally broken down volcanic rocks. Peridot is usually more concentrated in these areas because water carries away lighter materials while leaving behind heavier minerals.

This makes it easier to spot the olive-green crystals among the gravels and sands that have accumulated over time.

Old Mining Areas

Visit abandoned mine dumps and tailings, particularly those known for copper or nickel mining operations that were active in volcanic regions.

These areas often contain peridot as a secondary mineral, and since the rock has already been broken down during previous mining operations, the gems are easier to spot.

The types of Peridot you can find around the state

Peridot in West Virginia is usually found as rough, unpolished stones nestled in volcanic rock. Their olive-green to yellowish-green hues stand out, and the glassy or waxy surface gives a hint of their gemstone potential.

While the vibrant colors of Burmese or Arizona peridot may not be common here, West Virginia’s peridot has its own charm. The volcanic formations often reveal stones with unique patterns, making each find an exciting and special treasure.

Some Great Places To Start

Here are some of the better places in the state to start looking for peridot:

Martin Marietta Company Quarries

The Martin Marietta Company Quarries in West Virginia offer a unique spot for peridot hunting. Located near Martinsburg, these quarries are known for their volcanic rock deposits, which may contain peridot crystals, but permission is required before exploring.

To find peridot, search around the basalt rock formations where the gems tend to settle. Keep an eye out for loose rocks or rubble, as these areas may reveal hidden treasures, but always remember to get the proper permission before you start your hunt.

Limestone quarries

Limestone quarries in West Virginia are a good spot for peridot seekers. These quarries expose volcanic rock layers, where peridot crystals can sometimes be found, but access is typically restricted, so permission is required before starting.

The best hunting spots are in the dark green or black rocks near white limestone walls. Many hunters use small brushes to sweep away dust and spray bottles of water to make crystals easier to spot.

Iron Mountain

Iron Mountain, located in West Virginia, is another prime location to search for peridot. Known for its volcanic rock formations, the mountain’s exposed basalt can sometimes reveal hidden peridot crystals within its layers.

To find peridot, focus on areas where the basalt has cracked or eroded over time. These weathered sections are more likely to have loose peridot crystals that can be easily spotted among the rubble and rocky terrain.

Lost River area

The Lost River area in West Virginia offers a unique opportunity for peridot hunters. This region, rich in volcanic activity, features basalt rock formations where peridot crystals can sometimes be found, especially after heavy rains or erosion.

Check the rocky slopes where old lava flows meet the riverbed – this is where the best crystals often hide. Bring a spray bottle of water and a small rake to carefully move rocks aside, since many good pieces are tucked just below the surface where rushing water hasn’t carried them away.

Shannondale area

The Shannondale area in West Virginia is a hidden spot for finding peridot due to its volcanic rock formations. The exposed basalt layers here are great for discovering peridot crystals, especially where the rocks have cracked or weathered over time.

Look along the edges of basalt outcrops or in areas with loose debris, as peridot crystals may be tucked inside. After rainfall is the best time to search, as the peridot is more likely to be uncovered by the water.
