No Two Granite Slabs Are EVER The Same, And Here’s Why

Look at the two stone slabs pictured above. What do you see? Both are pretty close to looking identical, but their etchings and color tones are not the same. What you’re seeing is true for almost all granite slabs because of how they are produced. No two granite slabs are identical. Continue reading to uncover why this is true!

How Granite Came To Be

Are you ready for a quick geology lesson? Granite is one of the finest countertop surfaces available today. It is a type of igneous rock, meaning it was derived from molten rock that has cooled within Earth’s crust. When rock like this cools, crystals form from the minerals within the rock. The size of these crystals, also known as grains, is dependent on the speed the rock cools. Since the rock isn’t expelled from the crust during the cooling process, it results in variations of grains, allowing you to easily identify many different hues within one slab.


To be considered granite, the rock must contain at least 20% quartz, which is typically more white in color tone. Other minerals that makeup granite include feldspar, potassium feldspar, and amphibole. All of which contain and add color.

Breaking Down Terms

Before we continue, let’s define some of these minerals, so you know what’s really in your granite at home. 

Feldspar: This mineral makes up more than half of Earth’s crust. It is a group of aluminosilicate minerals that contain calcium, sodium, or potassium.

Potassium Feldspar: This refers to the five primary minerals that fall within the feldspar grouping mentioned above.


Amphibole: This is a group of inosilicate minerals forming prisms or needlelike crystals that generally contain iron and magnesium ions in their structures.

Color Tones Explained

So, you have the geology lesson and terms broken out. Let’s talk examples. If the granite formed has a lot more amphibole and quartz, it is most likely to be speckled black and white. However, if it is formed with a lot more potassium feldspar, it is likely to have a salmon-pink tone. Any granite formed with mostly only quartz is expected to have a milky white appearance. Lastly, any granite formed with mainly amphibole will produce a green or black tone. 

Not only is granite heat-resistant, scratch-resistant, and stain-resistant, every slab is UNIQUE. How special do you feel knowing there is no other granite slab perfectly identical to the one that might already be installed in your kitchen? Not only does granite have premium benefits, but searching for the right stone can be ten times more fun, knowing all are different. While you might like the look of one, in particular, you might like a separate slab of it better due to its coloring or etching. The best part? The choice is up to YOU to decide, and our Stone Squad is ready to assist you in hunting for the right one that will turn your vision into reality.
