How to Tell the Difference Between Granite and Quartz

The differences between granite and quartz

For many of us, choosing a kitchen worktop comes down to just one thing – which one looks best? However, while you don’t need to understand the intricacies of the material used for your worktop, having a basic understanding of the stone available can give you a real advantage in understanding which is the best for you. The two most popular materials we supply for kitchen worktops are granite and quartz. To help you understand the differences between the two we’ve summed up some of the key points below:

Where it comes from

As a 100% natural material that comes directly from the earth, the patterns, texture and colours within your granite countertop will be unique to your slab. Granite is formed from molten magma and consists of granite, feldspar and mica. At County Stone we only use the very best granite slabs and our qualified Stonemasons ensure that the measurements and cut is just right.

In a quartz countertop, quartz is a component coupled with another material to produce the required look. At County Stone we provide three different types of quartz. These are:

  • Silestone – comprising of 94% natural quartz making it tough and resilient. This manufactured worktop provides antibacterial protection.
  • Caesarstone – containing 93% natural quartz combined with numerous polymers and pigments.
  • Compac – a mixture of natural quartz, pigments and resins producing a surface which retains the beauty of the natural stone but with additional enhancements to make it scratch resistant and non-abrasive.


While granite is considered to be the strongest of all materials, providing you with a robust countertop for years to come, quartz has been manufactured to ensure that not only is it a strong material, it is actually more flexible. During installation, this makes it easier to achieve a good fit. Interestingly, quartz is the heavier of the two materials.


Granite is a porous material so to keep your granite countertop looking as good as new, we use a sealing agent called Drytreat upon installation. This comes with a fifteen-year guarantee and will need to be re-treated after that time has passed. Furthermore, to ensure your sealant remains working efficiently, you need to be careful how you clean your granite surface, above all not using cleaning products which might contain abrasive materials.
In comparison, quartz worktops are virtually maintenance free. Quartz is a non-porous material so doesn’t need to be sealed to protect it from stains in the same way that granite worktops do. They are also extremely hygienic as there is nowhere for bacteria to adhere to and grow.


As we’ve already touched upon, granite provides you with a really natural look which means you might get some imperfections coming through – something that people either love for the uniqueness or hate for the lack of consistency.
If uniformity is what you are after quartz is your better bet, as any imperfections are manufactured out.
If you are having trouble deciding between a granite or quartz kitchen worktop, the best thing you can do is to have a look at them. Our showroom, based in West Sussex, is open Monday-Friday so give us a call to arrange to come and see what we have to offer.
