What are Cool Rocks?

Cool rocks are those that stand out due to unique or interesting features. Characteristics that can make rocks cool include:

  • Vivid colors – Rocks like bright ruby-red garnets or multicolored tourmalines catch the eye with their intense hues.
  • Interesting shapes – Some rocks form fascinating natural shapes like cubes in pyrite or lovely crystals in amethyst geodes.
  • Fossils & imprints – Finding plant or animal fossils preserved inside rock layers adds historical value.
  • Special properties – Rocks that glow under UV light or react strongly to magnets have intriguing properties.
  • Metallic flecks – Sparkly specks of gold, silver, or copper gleaming from a stone can make it more desirable.
  • Locale – Rocks found in unusual or faraway places capture the imagination. Space rocks and gems from exotic locales are extra cool.

So, the “cool factor” of rocks comes from characteristics that make them visually stunning, rare to find, or tell an intriguing geological story about our planet and its past. The more unique or special attributes a rock possesses, the cooler it becomes to rockhounds and collectors.

There are many other gorgeous and interesting rock varieties that collectors seek out, like lapis lazuli, malachite, and labradorite. The colors, crystals, fossils, shapes, and metaphysical properties determine a rock’s allure and “cool factor”! Below are some rocks commonly regarded as “cool rocks” by collectors:

Rose Quartz

Quartz is the hardest of common minerals. The only minerals that are harder than quartz are diamonds. Its composition is silicon and oxygen, with a clear, glass-like appearance. Its pink hue is believed to be caused by tiny fibers of dumortierite inside the quartz.

As you know, rose quartz has ornamental purposes, such as figurines, vases, and jewelry.


From the Sanskrit “upala,” which means stone, Opal, like Ammonite, originates back in the Jurassic Period. Opal is formed from water and silicon and is famous for its stunning, vibrant colors.


The light-colored granite igneous rock has little grains on it. It is formed from the crystallization of magma underneath the Earth’s surface. It Contains quartz, feldspar, mica, and others. Its colors varied from red and pink to gray and white.

Granite can be used as decorative rock, mostly in countertops, tile floors, stair treads, and many other creative ways!


Turquoise is a blue-to-green mineral formed by percolating acidic aqueous solutions during the oxidation of other minerals. Its name comes from the French, meaning “Turkish stone.”

It looks beautiful and has been used as a gemstone for thousands of years. Jewelry-related, it is one of the most known gemstones out there that can transform your look from an 8 to a 10!

TIP: Turquoise is a very popular gemstone. How common is turquoise in the U.S., and where can it be? Find out more in the article below:

Obsidian is a kind of igneous rock. It has a dark color, sometimes green, sometimes brown. It is made out of solidified lava. The problem with this rock is that it doesn’t last a lifetime. In time, the glass transforms itself into fine-grained crystals. 

Obsidian was used in the Stone Age to create axes, arrowheads, and weapons. Nowadays, sharp blades are made out of them for heart surgery purposes.


Unakite is an olive green-looking gemstone known as the “Unakite Jasper.” It is made of quartz crystals, green epidote, and pink orthoclase feldspar. 

The name was coined in North Carolina. Unakite is not a popular gemstone, but it is used in hippie-style jewelry for people who like their bling with an edge!

Fool’s Gold ( Iron Pyrite)

Fool’s Gold ( Iron Pyrite)

Pyrite gets its nickname “fool’s gold” from the Greek word “pyr,” meaning “fire rock.” People used to strike this mineral against steel to make sparks and start fires. With its bright golden hue and metallic shine, pyrite is often mistaken for real gold.

During the gold rush era, prospectors aiming to strike it rich felt great disappointment upon realizing they discovered pyrite instead of real gold, hence the “fool’s gold” moniker.

Pyrite is the most well-known sulfide mineral and contains iron, though it is not commonly used as an iron ore. Other minerals like hematite and magnetite provide more economical sources of iron extraction. Still, pyrite remains popular among mineral collectors for its classic cubic shape and pale gold color, which seems to hold opportunities even if it does turn out to be “fool’s gold.”

TIP: Pyrite is believed to be quite a common mineral; however, pyrite fakes can sometimes be spotted. Find out more about the differences between real and fake pyrite in the article below:

Ammonites were prehistoric sea creatures that resembled present-day nautilus shells. Related to octopuses, squid, and cuttlefish, these marine mollusks lived during the Mesozoic era between 252 to 66 million years ago.

Ammonites had coiled shells acting as flotation devices, allowing them to freely drift in the open water. The shells were partitioned into chambers, much like nautilus shells today. As the ammonite grew, it would seal off older chambers and create new, larger ones.

Meteorites or Tektites

Tektites are the driest minerals on Earth ( very low on water ). They are made of terrestrial rocks and have a homogenous composition. They are believed to be the result of meteorites hitting the Earth.

They are found in different shapes, such as spheres, disks, or teardrops, and are very easy to store because they don’t rust in time.


Geodes are spherical rocks that carry hollow cavities lined with crystals. Its name comes from Greek, and it means “earthlike.”

They are formed in volcanoes or sedimentary rock, in which air, mud, or tree roots make a void in the rock while the exterior hardens into a spherical form.

Then, the groundwater filled with minerals starts flowing around and through these geodes. You can see the result of nature’s process if you crack open a geode and see the magnificent crystal inside its cavity.

You can find geodes worldwide, especially in deserts, volcanoes, and places with limestone.

TIP: Are you fascinated by geodes? If so, knowing how to recognize fake and real or dyed geodes is good. Find out more in the article below:

Tips on How to Find Cool Rocks

Contrary to popular belief, stunning rocks can be unearthed right in your backyard, not just in museums or jewelry stores. Common backyard treasures like quartz, turquoise, jade, garnet, opal, and tourmaline are gems you might uncover simply by stepping outside and exploring.

A great place to search for rocks is near city roads. Especially if there are road cuts, there’s a high chance you will find cool gems. 

Do you have neighbors whose land/house is under construction? Jackpot! If there’s any deep digging around, rock and soil are piled near the road. Grab your utensils and dig around! 

Another good spot for rockhounding is near forests. If you live surrounded by a forest, you can go for a morning walk and be amazed by its treasures.

Fossils and petrified wood can be found in areas with loose rocks and small cliffs. Bear in mind that forests might have lakes. Its shorelines hide beautiful gems such as geodes and agates.

Some useful yet necessary utensils that might help you are a pickaxe for chipping, a shovel if you need to dig deeper, a classifier to remove tiny gems, and tweezers just in case the rocks are too small.

TIP: Starting with rockhounding in your backyard is a great idea. You can find a lot of cool rocks there. Find out more about what rocks are common in the backyards and how to find them:

There are many ways to display your beautiful rocks! You can place them all over the house, put them on your shelves in huge jars, or keep them in bookcases. If you want more practical ideas, check them out by clicking here (Amazon link).

If you have a small collection, another great idea is to store them in a box. This allows you to travel safely and organize them by color or size.

If you’re feeling fancy, you can purchase big clear cases just like the ones in museums! Cases like this provide the necessary protection for your precious gems. Plus, you’ll give your house a distinct chic vibe! 

If you don’t want to spend money on useless shelves and cabinets, you can always DIY! Get tiny cardboard boxes and put them in bigger ones, paint them in whatever color you choose, and there you go! You now have a beautiful set-up! 

Either way, whatever you choose, stones give any place a cool, edgy vibe. And it’s not just about the looks – the different metaphysical properties have made them almost necessary in every home!
