Yes, right in your own backyard, there lies a potential wealth of precious stones just waiting to be discovered. But what are these rocks, you ask? Well, let’s just say that they range from mesmerizing jade to sparkling quartz, from stunning agate to mysterious obsidian. And that’s just the beginning.

So, if you’re curious to know more about the 12 valuable rocks that could be hiding beneath your very own soil, keep reading.


Jade is a highly valuable gemstone that can be found in various locations across the US, such as coastal California. It’s known for its smooth surface, dense grain, hardness, and distinct color.

Jade is one of the most sought-after gemstones due to its beauty and rarity. When it comes to finding valuable stones in your backyard, jade should definitely be on your radar.

Jade is a unique stone that has been treasured for centuries. Its smooth surface and dense grain make it a popular choice for jewelry and ornamental purposes. The hardness of jade, which ranges from 6 to 7 on the Mohs scale, ensures its durability and longevity. This durability is one of the reasons why jade is considered so valuable.

The distinct color of jade further adds to its allure. While jade is commonly associated with shades of green, it can also be found in other colors such as white, black, and lavender. The vibrant green jade, in particular, is highly prized and often fetches a higher price in the market.

Coastal California, including locations like Big Sur and some beaches in Norcal, is known for being a hot spot for finding jade. The rich geological history and favorable environmental conditions in these areas contribute to the presence of this valuable gemstone. So, if you’re lucky enough to live in one of these regions, you might just stumble upon this precious stone in your own backyard.


Quartz, a widely distributed and valuable mineral, can be found in various states across the US, often nestled in clay-type soils or within vugs in the bedrock. This gemstone isn’t only aesthetically pleasing but also holds significant value. In states like Arkansas, New York, and California, even small quartz points can fetch a few bucks each. The different growth patterns of quartz can further enhance its value, making it a sought-after find for those in the right areas.

When searching for quartz, it’s important to know what to look for. Quartz crystals should feel cool to the touch and have a clear appearance. Amethyst, a rarer form of quartz, is a purple crystal that can also be found in various states across the US. So, keep an eye out for this stunning variation as well.

To find quartz, start by checking your front yard, including the driveway. Quartz can easily blend in with normal rocks, so it’s important to give them a closer look. Use a pocket knife to scratch the surface of the rock. If it leaves a mark, then it’s likely not quartz. However, if it doesn’t leave a mark, there’s a good chance it could be quartz.

Once you have confirmed that you’ve found quartz, you can capitalize on its value. Quartz can be used in jewelry making or sold as individual specimens. Its versatile nature allows for various creative uses, ensuring that you can make the most out of your valuable find.


Agate, a unique and captivating rock formation, is characterized by intricate bands, trapped mosses, and an array of vibrant colors. This stunning gemstone can be found in various parts of the world, including California. Agate comes in the form of small nodules, and different localities often have specific agate varieties with varying values.

When searching for agate in your backyard, keep an eye out for rounded, slightly irregular nodules. These nodules can range in size from small pebbles to larger rocks. One distinguishing feature of agate is its waxy-feeling portions. If you come across a rock with a smooth, almost greasy texture, chances are you’ve found agate.

Agate is one of the valuable rocks commonly found in California. Nipomo Agate is an example of a highly sought-after variety. It’s known for its distinct banding patterns and beautiful colors, which can include shades of blue, green, and brown. Due to its rarity and aesthetic appeal, Nipomo Agate is often used in jewelry.

In addition to Nipomo Agate, there are many other types of agate that can be found in California. These gemstones include Laguna Agate, Mojave Agate, and Botryoidal Agate. Each variety possesses its own unique characteristics and can add a touch of natural beauty to any piece of jewelry.


After exploring the valuable rocks of agate in your backyard, let’s now turn our attention to the fascinating world of obsidian. Here are some interesting facts about this intriguing gemstone:
