Discover the treasures hidden beneath your feet with common crystals you can find in your backyard, such as quartz, calcite, mica, and more.
Can You Find Valuable Crystals in Your Backyard?
Many people don’t realize that a treasure trove of beautiful crystals and minerals can potentially be found right in their own backyards. With a bit of digging in the dirt and peering into rocks, you may be able to uncover gorgeous specimens like quartz, calcite, mica, and more that have formed naturally close to home.
In this blog post, we'll cover some of the most common backyard crystals and where to look for them. Crystals start forming when minerals slowly precipitate out of solutions over hundreds or thousands of years. Tectonic movements and changes in temperature and pressure cause crystals to take shape in rocks, sediments, and even shells. Knowing the geological history of your area can help you identify what crystals you may find locally.
We'll go over common gemstones and crytals like quartz, calcite, pyrite, garnet, feldspar, obsidian, and mica – what their characteristics are and where they are more likely to be found. With some patience and curiosity, you can find amazing examples of these crystals weathering out of rock formations, in gravel and soil, and elsewhere on your property. Who knows what amazing formations you can unearth?
So grab a magnifying glass, shovel, and container and let's start exploring your backyard to uncover gorgeous, hidden crystals and sparkling minerals waiting to be found! The treasures we can discover so close to home can be truly dazzling.

These Common Crystals Could be in Your Backyard
Quartz is one of the most abundant crystals on the planet: and one you can likely find in your own backyard. Made up of silicon and oxygen (silicon dioxide), quartz forms in rocks in various colors, across many different environments. Look for it weathering out of granite, shale, sandstone or limestone deposits. Quartz has a classic clear, glassy appearance and comes in crystal points, clusters, or masses. Varieties to look for include:
- Rock crystal – Clear, colorless quartz
- Amethyst – Purple variety of quartz
- Rose quartz – Pink variety of quartz
- Citrine – Yellow to orange quartz
- Smoky quartz – Gray to brown quartz
Calcite is a common calcium carbonate mineral that crystallizes in sedimentary rocks such as limestone and dolomite. Check gravel made from crushed limestone or pick through seashells where calcite crystals often form. Calcite grows in crystal formations like columns, scalenohedrons, and rhombohedrons. Look for calcite in white, yellow, orange, pink or even blue varieties.
Mica is a sheet silicate mineral found in metamorphic and igneous rocks. Look closely in schist, gneiss, granite, or rocks with mica flakes visible. Muscovite mica is clear while biotite mica is black. The thin sheets can peel off in layers. Mica “books” form when sheets are stacked together.
Fool's gold, pyrite, is an iron sulfide mineral that crystallizes in cubes, pyritohedrons, or nodules. Its brassy, yellowish metallic color gives it a gold-like appearance. Pyrite needs iron to form, so check shale, coal, or other iron-rich sediments. It often sticks out from a rock's surface.
Obsidian is volcanic glass, not a true mineral, but it can contain crystals. It forms when lava or molten rock cools rapidly with minimal crystal growth. Look for shiny black obsidian in old lava beds or near volcanically active (or formerly active) areas. You may find rounded nodules or jagged chunks of this natural glass. You can also find other kinds of volcanic rocks, like porous lava rock. Obsidian and lava rock are commonly found in the Southwestern United States.
The feldspar group includes tectosilicate minerals like orthoclase, plagioclase, and others. Granite, pegmatite, and gneiss commonly contain feldspar crystals. Look for pink, white, or gray blocky crystals, sometimes in glassy formations. Cleavage planes meet at 90 degree angles.
Garnet is a silicate mineral that crystallizes in cubic forms in metamorphic rocks like shale, schist, and gneiss. The deep red color comes from iron. Garnet also comes in other colors like yellow, brown, and green. Look in sedimentary or metamorphic rocks near you.
With patience and sharp eyes, you can uncover amazing crystal treasures in your own backyard. Use a rock hammer, chisel, or shovel to split open promising rocks or break apart sediments. See what dazzling crystals, with natural geometric shapes and brilliant colors you can unearth close to home.
Factors Influencing Crystal Presence
The makeup of the soil in a particular region plays a pivotal role in determining the types of gems and mineral specimens that can be found there. Soil is not just the dirt we see; it's a complex matrix formed from the breakdown of rocks, organic matter decay, and various physical and chemical processes.
Sandy Soils: Comprising mainly sand particles, these soils are often the result of the weathering of rocks like granite. They might be rich in quartz, given that sand is essentially tiny fragments of quartz. The well-draining nature of sandy soils means water-soluble minerals may be less common here.
Clayey Soils: This type of soil has finer particles and tends to retain water. Feldspar, which decomposes to form clay minerals, might be present, as well as mica which gives the soil a slightly shiny appearance when viewed at certain angles.
Loamy Soils: An ideal mixture of sand, silt, and clay, loamy soils can host a range of minerals, depending on the rock sources they originated from and their specific environmental history.
The story of the land plays out in the rocks and minerals that are present. Each region has a unique narrative, shaped by millions of years of tectonic movements, volcanic activities, erosional forces, and sedimentary processes.
Volcanic Terrains: These are birthplaces of igneous rocks. Obsidian, a volcanic glass, might be found in such areas. Pumice, basalt, olivine (peridot), and varieties of quartz like amethyst can also be linked to volcanic activity.
Sedimentary Environments: Places where ancient seas, lakes, or rivers once flowed can be rich in sedimentary rocks. Calcite, formed from the skeletal fragments of marine organisms, is commonly found here. Gypsum and halite (rock salt) might also form in evaporative environments.
Metamorphic Regions: Areas subjected to intense heat and pressure might have metamorphic rocks. Crystals like garnet, kyanite, and staurolite can be found in these zones.
Over the ages, human beings have altered landscapes in significant ways. Every time the earth's surface is dug up or moved, there's a potential to reveal what's hidden beneath.
Mining: Intentional digging to extract valuable minerals or fuels can expose a multitude of popular gemstones and crystals. Even abandoned mines can be a treasure trove, though one should always exercise caution and seek necessary permissions before exploring such areas.
Construction: Urban development often requires extensive excavation. This disturbance can bring to the surface buried geological formations and their associated minerals.
Agricultural Activities: Tilling, plowing, and other agricultural practices can sometimes churn up stones and crystals from deeper layers of the soil to the surface.
River and Stream Erosion: Human activities that alter the course or flow of water bodies like creek beds, streams, and river beds can lead to erosion, which may expose buried rocks and minerals.
When exploring any area, it's vital to remember that the presence of specific crystals isn't guaranteed. Each patch of land has its unique history and composition and can vary greatly, with even small changes in geographical location and geology.
