While not as common as quartz or jasper, these bright blue stones can be found in several California counties. The right locations and proper searching techniques make all the difference.

How Lapis Lazuli Forms Here

Lapis Lazuli forms deep within metamorphic rocks when limestone or marble undergoes intense pressure and heat. Different minerals come together during this process, mainly lazurite, pyrite, and calcite.

Pressure from the Earth’s crust transforms these minerals into the distinctive blue stone we know. Heat plays a crucial role by helping the minerals crystallize properly.

Multiple mineral components mix during formation, creating those white and gold streaks you see.

Creating this stone takes millions of years of perfect conditions. Nature has to maintain just the right temperature and pressure throughout the process.

Sometimes, other minerals like sodalite and hauyne join the mix, affecting the final color. Rocks surrounding the forming Lapis Lazuli also influence its quality and appearance.

What Rough Lapis Lazuli Look like?

Lapis Lazuli in its rough form can be tricky to identify, especially when you’re just starting to explore rocks and minerals. Here’s how you can spot this royal blue beauty without needing fancy equipment.

Look for the Signature Deep Blue Color

The most striking feature of rough Lapis is its deep, intense blue color – think midnight sky or ocean depths. But it’s rarely just blue. You’ll often spot tiny gold-colored flecks (pyrite) scattered throughout, like stars in the night sky.

Sometimes you might see white streaks or patches (calcite). If the blue looks too bright or artificial, it might be dyed sodalite or howlite instead.

Check for a Glassy to Waxy Surface

Run your fingers over raw Lapis – it should feel smooth but not quite glassy. Unlike polished pieces, rough Lapis has a somewhat waxy or matte appearance.

Look for areas where the surface seems uneven or slightly greasy. These characteristics come from its metamorphic nature.

A quick tip: if it’s super glossy or feels plasticky, it’s probably fake.

Assess the Hardness Through Simple Tests

Grab a copper penny and try to scratch your specimen. Lapis ranks 5-5.5 on the Mohs scale, so it shouldn’t scratch easily with a fingernail (2.5) but will yield to a steel knife (5.5).

Don’t go crazy with scratching – just test a small, inconspicuous spot. The stone should feel solid and compact, not crumbly or soft like chalk.

Watch for Key Mineral Inclusions

Take a close look at the stone’s surface – authentic Lapis Lazuli typically contains visible mineral inclusions.

The most common are golden pyrite specks, which appear as metallic flecks throughout the blue body. White or grey streaks of calcite are also normal and can range from thin veins to larger patches. Dark spots or areas are usually other minerals like sodalite or lazurite.

A uniform, perfect blue color without any inclusions is uncommon in natural Lapis and might indicate a fake stone. Use a magnifying glass if available – it helps spot these mineral patterns more clearly.

Tips on Where to Look

Finding Lapis Lazuli can be tricky but not impossible if you know where to look. Here are some common places where you might get lucky with this beautiful blue stone.

Limestone Deposits

Look for white to grayish limestone areas. Lapis often form near limestone because both need similar conditions to form.

Check for blue veins or patches in limestone outcrops. If you spot calcite or pyrite nearby, that’s a good sign.

The presence of white marble alongside limestone makes it an even better spot since Lapis Lazuli typically forms when limestone transforms into marble through intense heat and pressure.

Mountain Quarries

Active or abandoned quarries are goldmines for Lapis hunters. Focus on areas where they’re cutting into metamorphic rocks. The freshly exposed rock faces make it easier to spot the deep blue color.

While exploring these sites, keep an eye out for rocks with a mix of blue and white – that’s often how Lapis appears in its raw form. Sometimes, you might need to crack open seemingly ordinary rocks to reveal the blue treasure hiding inside.

Crystal Seams

Search for crystal veins in rocky areas. When you find one crystal type, there’s a good chance you’ll find others nearby, including Lapis.

Look for areas where different rock types meet – these contact zones are perfect spots for Lapis formation.

While you’re checking these seams, which can sometimes stretch for several feet along rock faces and often contain multiple types of minerals clustered together, pay special attention to areas where you see dark blue or deep purple colors peeking through.

River Beds

Check river beds and gravel bars, especially after heavy rains when new material gets washed down. Focus on areas where the water slows down – that’s where heavier stones like Lapis tend to settle.

Pro tip: dig about 1-2 feet deep in these spots, as heavier stones often sink below the surface materials.

Some Great Places To Start

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

San Bernardino Mountains

Located north of San Bernardino city, these mountains are part of both San Bernardino and Riverside counties. The area is famous for its remarkable blue Lapis Lazuli deposits.

Rock hunters often find success searching near old mining sites in the mountain’s western region. Many collectors explore the metamorphic rock formations, where Lapis Lazuli typically forms. The mountains have plenty of exposed rock faces and mineral-rich areas created by ancient fault movements.

These mountains sit where two major fault lines meet – the San Andreas and San Jacinto faults. This special location created perfect conditions for various minerals to form.

The highest point, San Gorgonio Mountain, stands at 11,503 feet and offers several good spots for mineral hunting.

Big Horn Mine

Big Horn Mine sits about 90 minutes from Los Angeles. This old gold mine has a rich history dating back to 1895 when it was first discovered by Charles Tom Vincent. The mine stretches deep into the mountain and has many tunnels and shafts.

Lapis Lazuli shows up here in thin blue lines mixed with silver-colored pyrite in the rocks. These blue stones are most common near the old mining tunnels and along the exposed rock walls. The area also has other interesting minerals like gold and quartz.

Getting to the mine takes a moderate 4-mile round trip hike from Vincent Gap. The trail offers amazing views of the San Gabriel Wilderness and Mine Gulch.

Rock hunters should look closely at the metamorphic rocks around the mine entrance and along the ridge between the north and south forks of Cascade Canyon. The blue streaks of Lapis often appear in bands within these rocks.

San Gabriel Mountains

The San Gabriel Mountains stretch across northern Los Angeles County. These mountains sit between Los Angeles Basin and the Mojave Desert.

Rocks in this area formed over millions of years through a mix of heat and pressure. Small granite masses pushed into older rocks, creating perfect conditions for Lapis Lazuli to form. Blue veins of this stone run through the rocks, often sparkling with bits of silver pyrite.

Besides Lapis Lazuli, these mountains are also home to other interesting rocks and minerals. The area shows clear signs of how rock layers changed over time, making it special for both casual collectors and serious rock hunters.

Mojave Desert

The Mojave Desert is a vast arid region located in southeastern California. It spans across parts of California, Nevada, Utah, and Arizona. In California, it is situated primarily in the southeastern part of the state.

Ancient rocks here tell a story that goes back more than 2 billion years. Blue Lapis Lazuli has been discovered in several spots throughout this desert, making it special for gem hunters.

Mountains and valleys shape this desert landscape. The Sierra Nevada mountains stand tall on the western edge, while the Colorado Plateau marks its eastern border. Hot summers and cool winters create perfect conditions for rock hunting year-round.

Volcanic activity from long ago left behind interesting rock formations. These old volcanic areas are good spots to look for Lapis Lazuli. Rock hunters often find success searching near the desert’s metamorphic rock areas, especially where limestone meets other rock types.

Haystack Butte

Haystack Butte stands 3,379 feet tall and got its name from its distinctive shape that looks like a giant pile of hay. Rock collectors often visit this area to search for Lapis Lazuli, a bright blue stone with golden specks.

Gemstone hunters can find Lapis Lazuli in the white limestone areas of the butte. The best spots are near old stream beds and small canyons where water has washed away loose soil. Many pieces have been found where marble meets other types of rock.

Local rock clubs often plan group trips to Haystack Butte because it’s one of the few places in California where you can find good quality Lapis Lazuli. The area also offers great views of the surrounding landscape.
