Crystals and gems form in different locations within the Earth, in dissimilar environments. Crystals are brought to the surface through faulting, folding, large-scale uplift, mining, and volcanism as with amethyst blue-purple crystals. Finding crystals can be daunting at first until you know where to look. In this article, you’ll learn about how to find crystals.
How To Find Crystals? Important Points
Research State Mining and Mineral Departments:
Most states have a department that oversees mining operations within its boundaries that you can review online. These sites typically identify the minerals, gems, and precious metals being mined within the state along with maps of current and abandoned mining locations. Check for inactive mining claim locations to avoid encroaching on someone’s claim. Since many crystals are removed from the earth through mining operations, start by visiting old mining claims and rummaging through the tailing piles alongside mine adits but not inside tunnels, as these areas can be unsafe. So wear heavy gloves and keep on the lookout for deadly snakes, depending on the area and the season.
Earthquake Fault Zones:
Areas on the planet’s surface that show clear evidence of fault lines and uplifts offer an ideal location to hunt for crystals. Check the area for ribbons of white quartz, which can also be found near known granite and gold deposits. Abandoned quarries where sand and gravel have been removed provide another location where crystals can sometimes be found, depending upon the geology of the location.
Hydrothermal Springs and Road Cuts:
Many crystals form through hydrothermal processes beneath the ground and are sometimes brought to the surface near hot springs locations. Opals, agate, and amethyst crystals and gems are often found close to these types of locations, where heated waters push their way through to the surface. Any place that has been dug out, graded, or built up, such as in the cuts or trenches that occur alongside roads offers locations where crystals might be found.
Equipment and Safety:
Before you start, you’ll need some tools: a small rock hammer or geologist’s pick, a small bucket, a large or small cold chisel, and a mallet. When you hike in wilderness areas hunting crystals, wear tough work or safety boots that extend beyond your ankles for solid support when rummaging along hillsides. Carry a small first-aid kit, a canteen for water, and wear a hat to help keep you cool. So in areas where there are poisonous snakes and other wildlife, wear long-legged pants and be aware of your environment. Always tell someone exactly where you are going and how long you expect to be gone, and check in with them when you return.
What is a rock that has crystal?
Crystalline rock is any rock composed entirely of crystallized minerals without glassy matter. Intrusive igneous rocks those that congeal at depth are virtually always crystalline, whereas extrusive igneous rocks, or volcanic rocks, may be partly to entirely glassy.
How do you know if a rock has crystals in it?
Test whether the rock has a hollow interior.
Pick up the rock and assess its weight. If the rock feels lighter than the surrounding rocks, it may be a geode. And Geodes have a hollow space inside, which is what allows the crystals to form. You can also shake the rock next to your ear to test whether it is hollow.
Are crystals rocks?
Crystalline describes a naturally occurring solid made up of crystals. Crystals are not rocks because they’re made up of atoms.
Do igneous rocks have crystals?
Igneous rocks are formed from molten rock called magma. So they are mostly crystalline (made up of interlocking crystals) and usually very hard to break.
What rock contains large crystals?
Intrusive igneous rock
The type of igneous rock that usually contains large crystals is intrusive igneous rock.
Which rock has the largest crystals?
The largest authenticated crystal of any type is beryl from Malakialina, Malagasy Republic, being 18 m in length, 3.5 m in diameter, having a volume estimated at 143 m3, and a mass of approximately 380,000 kg.
Where can you find crystals in nature?
Areas on the planet’s surface that show clear evidence of fault lines and uplifts offer an ideal location to hunt for crystals. So check the area for ribbons of white quartz, which can also be found near known granite and gold deposits.
How do I know if I found a crystal?
Look at the crystals in the rock using a magnifying lens. So use a book that identifies types of rocks and crystals to identify the crystals in the rocks you are examining. And carefully examine the rock’s crystals and compare them to the pictures in the book. Find the one that looks most like the crystal in your rock.
How can you tell if a rock is quartz?
How to Identify Quartz;
- A glassy luster.
- Hardness 7 on the Mohs scale, scratching the ordinary glass and all types of steel.
- It breaks into curved shards rather than flat-faced cleavage fragments, meaning it exhibits conchoidal fracture.
- So it is always clear or white.

Frequently Asked Questions
Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth’s crust. They are crystalline and often have a “squashed” (foliated or banded) texture.
As a mineral name, quartz refers to a specific chemical compound (silicon dioxide, or silica, SiO2), having a specific crystalline form (hexagonal). It is found in all forms of rock: igneous, metamorphic, and sedimentary.
Rocks that are valuable because of their history are more likely to show up at an auction, pawn shop, jewelry store, or yard sale. A quartz crystal discovered 120 years ago will be worth much more than one that was found last year.
Quartz’s clarity earns it a raw price of around $0.01/carat and a gem price of $1-$7/carat. Amethyst, or purple quartz, is the most valuable variety (can reach $15/carat), but pink, rose, and smoky quartz is also valuable. Clearer, more vibrant, and unbroken specimens are the most valuable quartz.
