The first thing to understand about quartz is that it is not cut from the earth the way granite or marble is. Quartz countertops are engineered, made by combining crushed quartz crystal, roughly 90 percent or more, with resins and pigments to form a slab. That manufacturing process is exactly what gives quartz its identifying traits.
At Granex, we carry quartz countertops alongside natural stone, and we walk customers through the differences in person because the two categories can look similar in photos but behave very differently in a kitchen.
Look at the Surface Texture and Consistency
Run your hand across a quartz slab and you will typically feel a smooth, even surface with almost no texture variation from one end to the other. Natural stones like granite or marble often have subtle pitting, texture shifts, or mineral flecks you can feel as well as see.
Quartz also tends to feel slightly warmer and less cold to the touch than dense natural stone, since it contains resin rather than being pure mineral. It is a small detail, but it is one of the quickest ways to tell what you are looking at in a showroom.
Check for Repeating Patterns
Because quartz is manufactured in batches, the same pattern often repeats across a slab, and sometimes across multiple slabs from the same production run. If you look closely at a large sample and notice the same swirl or fleck cluster showing up more than once, that is a strong sign you are looking at quartz rather than natural stone.
Natural stone, by comparison, never repeats. Every vein and mineral deposit in a granite or marble slab formed over a much longer timeline, so no two sections look identical, even within the same slab.

Ask About the Quartz Content
A legitimate quartz product will list its quartz content, generally in the 90 to 95 percent range, with the remainder made up of resins and pigments. If a supplier cannot tell you what percentage of the material is actual quartz, that is worth asking more questions about before you buy.
Our team can walk you through the specifications of the quartz lines we carry, including what goes into the surface, so you know exactly what you are bringing into your Solon, Ohio home.
Compare Quartz to Quartzite While You’re At It
One of the most common mix-ups we see is between quartz and quartzite, which despite the similar name are completely different materials. Quartzite is a natural stone, formed from sandstone under heat and pressure, while quartz is engineered. You can learn more about how the two compare on our Know Your Stones page, which breaks down the makeup and properties of each material we work with.
Pro Tip: Ask to see the underside or a cut edge of any slab you are considering. Natural stone shows its mineral structure straight through the cut, while quartz reveals a more uniform, resin-bound cross-section. It is one of the clearest tells in person.
Why the Difference Matters for Your Kitchen
Knowing what you are buying affects more than just the look of your countertop. Quartz and natural stone perform differently around heat, staining, and day-to-day care, and understanding which one you have helps you use it the way it was designed to be used. Our Why Stone page covers some of the practical reasons homeowners choose one material over another.
