What Is California Quartz Anyway?
Quartz is a type of mineral that is very common and can be found all around the world. It’s made up of silicon and oxygen, and it forms a crystal structure that can be either clear or have different colors depending on the kinds of other minerals that are mixed in with it.
Quartz is known for being very hard and durable, which is why it’s used in making jewelry and in various industries.
The crystals of quartz can come in many shapes and sizes, and sometimes they’re so clear that they look like glass, while other times they can be cloudy or have a color like pink, purple, or yellow.
Quartz can be found in rocks on the beach, in the mountains, and in fields. Often, it’s found in places where there are a lot of volcanoes or where hot springs used to be. Quartz is formed below the surface of the Earth and rises to the surface over time.
This article was made to help you identify quartz by giving you a better idea of what it looks like.
Quartz is highly valued due to its unique combination of beauty, durability, and many uses. It’s one of the hardest rocks, so it doesn’t get scratched or worn down easily.

The Best Places To Find Quartz In California
Here is a list of our favorite quartz spots in the state. There are a lot of available places to find gems in California, but not all of them have quartz. Some of these places are great for looking, even though they aren’t as well known.
Always Confirm Access and Collection Rules!
Before heading out to any of the locations on our list you need to confirm access requirements and collection rules for both public and private locations.
These requirements are subject to change without notice and may differ from what we state below.
Always get updated information directly from the source ahead of time to ensure responsible rockhounding.
Greenhorn Mountain Park
It’s fun to go on adventures and learn about nature at Greenhorn Mountain. At more than 6,000 feet, it’s the tallest peak in the Greenhorn Range, which is part of the Sierra Nevada.
People love this mountain for its beautiful views and climbing trails, but it’s also a great place to find quartz. Geology is what makes Greenhorn Mountain a great place to look for quartz.
A very long time ago, there were volcanoes and hot springs in the area, which are ideal for the formation of quartz. Quartz crystals made their way to the surface over time as the earth moved and changed.
There are a lot of different kinds of quartz here. They can be clear and sparkly, or they can be different colors, like pink or yellow. Collectors will enjoy this because each piece is different.
Also, this quartz is known for being of high quality, which means it’s very clear and well-shaped.
Where we found quartz at the Greenhorn Mountain
Look for areas where the bedrock is exposed, as quartz veins can often be found in these outcrops. These veins are where quartz crystals form and can be a great place to find larger specimens.

Mokelumne River
Mokelumne River is a hidden gem for nature lovers and treasure hunters. It’s over 95 miles long and starts in the high Sierra Nevada and winds its way down through the foothills into the Central Valley.
It’s famous for its beautiful scenery and outdoor activities like fishing and kayaking. It’s also a popular place to find quartz.
The river flows through places that used to be volcanoes and have a lot of geothermal activity. These conditions are ideal for making quartz.
As the river cut its way through the mountains and valleys over time, it found and brought many minerals, including quartz crystals.
Some of these gems are clear, some are pink, and some are even smoky quartz. This variety comes from the fact that the river flows through different kinds of rock and dirt.
Where we found quartz at Mokelumne River
Quartz is often found along the sides of the Mokelumne River, especially where the water moves more slowly.
San Francisquito Canyon Reservoir
The peaceful and beautiful San Francisquito Canyon is known for its interesting natural history and beautiful scenery. The mountains near Los Angeles form this canyon, which is a peaceful place to get away from city life.
Not only does it have a lot of hikers and nature fans, but geology buffs, especially those who want to find quartz, know it well.
This area is in a region that has had volcanic action in the past, which made the conditions ideal for quartz to form.
Over a very long time, these quartz crystals slowly rose to the surface. The canyon’s varied landscape, with its rocky hillsides and creek beds, makes it easy to find these crystals.
Where we found quartz at San Francisquito Canyon
The creek that runs through San Francisquito Canyon is a good place to start. Quartz often gets washed down and settles in these areas. Look for spots where the water has moved rocks and soil, as this can uncover quartz crystals.
Sawmill Mountain
Sawmill Mountain, which is in the beautiful Tehachapi Mountains, is a popular place for rock hunters and people who love the outdoors.
With an elevation of over 8,800 feet, this mountain is a great place to walk and also a great place to find quartz. This place has a lot of natural past, which makes it a great place for quartz to form.
Volcanic action has changed the area, and the rocks and soil are good for quartz growth. As the earth moved and aged over time, quartz crystals rose to the surface.
You can find these crystals in a lot of different places on the mountain, from the rocky slopes to the more private areas with lush plants.
Sawmill Mountain’s quartz can be clear, milky, or even colored with pink or yellow minor minerals during its formation. As a result, the mountain is an interesting spot for rock collectors and people who are interested in geology.
Where we found quartz at Sawmill Mountain
Quartz often forms in and around rocky outcrops. On Sawmill Mountain, look for areas where the bedrock is exposed or where there are plenty of rocks and boulders.
Scott River
The Scott River is a secret gem for people who love nature and looking for lost treasure. This river flows through Siskiyou County and is famous for its clear water and great fishing.
It’s also a great spot to find quartz. Because the river goes through different types of rock, it’s a great place for people who like quartz.
In the past, there was a lot of volcanic activity and earth moving in the area around the river, where the conditions are right for quartz to form. As time went on, the river helped move these quartz diamonds into view.
Quartz here might be different from quartz in other places. If certain elements were present when the quartz formed, you might find clear, shiny pieces or quartz with hints of pink or yellow.
Where we found quartz at Scott River
The banks of Scott River, along with gravel bars within the river, are prime locations for finding quartz.

Common Quartz-Hunting Questions
If you want to know where to find quartz in the state, here are some questions that people often ask:
Is it illegal to collect quartz in California?
In California, the legality of collecting quartz and other minerals depends on several factors including the location and land ownership.
On many public lands, such as national forests and Bureau of Land Management (BLM) lands, casual rock collecting (meaning small amounts for personal use) is usually allowed without a permit.
However, there are restrictions to ensure the conservation of natural resources. It’s important to check the specific regulations for the area you are interested in, as some areas may have unique rules or may be protected and off-limits for collecting.
In state parks and other protected areas, collecting rocks, including quartz, is generally prohibited to preserve the natural environment.
Collecting on private land is illegal without the express permission of the landowner. Trespassing to collect rocks can result in legal consequences.
If you’re unsure, contacting the local land management office or visiting their website can provide you with the most accurate and up-to-date information.
