Let’s be real, quartz countertops are pretty much everywhere these days, and for good reason. They’re sturdy, they look amazing, and they’re a breeze to maintain. Unlike natural stones, quartz countertops are engineered, which means they’re not only strong but also super consistent in both quality and look. However, not all quartz surfaces are created equal. There’s a wide range of grades out there, and they can impact everything from how long your countertops last to how much you’ll be paying for them. So, how do you know if you’re getting the real deal or just a countertop that’s flashy but doesn’t hold up? In this guide, we’ll break down the quartz countertop grading system, so you can make sure you’re choosing the best option for your space.
What Are Quartz Countertop Grades?
Before we get into the nitty-gritty of costs, let’s first talk about why quartz countertops even have grades. Unlike granite, which comes straight from the earth, quartz is a manufactured material made from a mix of natural stone and resin. This means there’s a little more variation in quality, and that’s why grading becomes important. Whether it’s the materials, the finish, or the overall durability, the grade will tell you how much bang you’re getting for your buck.
Why Quartz Is Graded
Since quartz countertops are engineered, the grading system helps to indicate how solid, durable, and visually appealing the stone is. Every quartz surface comes with its own unique blend of materials, meaning some are built to last longer and look more polished than others. The grading system helps consumers like you tell the difference between:
- Material density and hardness (which affects longevity)
- Consistency of color vs. more exotic, intricate designs
- Thickness and overall strength of the material
- The quality of the finish (whether it’s polished or honed)
To put it simply: grading helps to differentiate between the countertop that’s just okay and the one that’s going to stand the test of time.
Breakdown of Quartz Grades
Alright, so now that you understand why quartz countertops are graded, let’s talk about what each grade means. Whether you’re working on a tight budget or designing your dream kitchen, understanding these levels will help you pick the perfect stone surface for your needs.
Level 1 – Entry-Level / Commercial Grade Quartz
Level 1 is your budget-friendly option, often found in rental properties or quick renovations. These quartz countertops typically feature:
- Thinner slabs (usually around 2cm, sometimes reinforced with plywood)
- Simpler, more uniform patterns
- Large-scale imports from places like China or India
Pros: Affordable, easy to find, and it’ll match with most cabinets.
Cons: Not as unique, may require extra support, and tends to have a more basic finish.
Level 2–3 – Mid-Grade Quartz
If you’re a homeowner looking for a solid balance between quality and price, mid-grade quartz countertops are where it’s at. They tend to be 3cm thick and come with smooth, glossy finishes. These surfaces aren’t as dramatic as the premium grades but still look fantastic and last long.
Best For: Family kitchens, long-term home upgrades, or anyone with a moderate budget.
Popular Picks: Calacatta Quartz, Carrara Quartz, Giallo Quartz
Level 4–7 – Premium / Exotic Quartz
If you’re all about making a statement, this is where the magic happens. Premium quartz countertops have rare color combinations, bold veining, and intricate patterns that scream luxury. These countertops often come from exclusive brands and manufacturers who use high-quality materials, making them more expensive but totally worth the splurge.
Characteristics:
- Striking patterns with high contrast
- Superior edge detailing and finishes
- Heavier slabs, with fewer imperfections
Ideal For: High-end kitchens, luxury homes, or anyone who wants a countertop that doubles as a conversation starter.
Factors That Influence Quartz Grade and Cost
Here’s the thing: just because two quartz countertops look similar, doesn’t mean they’ll cost the same. Several factors can affect both the quality and price of your countertop. Knowing what goes into these grades will help you figure out whether you’re getting a fair price.
Origin of the Quartz (Local vs. Imported)
Quartz that’s imported from places like China or India is often cheaper, whereas quartz from more exclusive locations (like Italy or Scandinavia) is pricier due to rarity and shipping costs.
Thickness of the Slab
Most quartz countertops come in 2cm thickness for entry-level options, but premium grades are thicker, typically 3cm or even 5cm. Thicker slabs are more durable and offer a higher-end aesthetic.
Color and Pattern Complexity
The more intricate and bold the pattern, the higher the cost. Basic, uniform patterns are more affordable, but unique veining and rare colors (think deep blues or dark reds) can raise the price. High-end patterns can really make your kitchen look like a work of art.
Finish and Surface Texture
The type of finish you choose can add to the overall cost. Polished surfaces are the most common and affordable, but honed, matte, or leathered finishes require more work, which means they come with a higher price tag.
Fabrication and Edge Style
Standard, straight edges are common, but if you’re going for a custom, ornamental edge (like ogee or bullnose), expect to pay a little extra. High-quality quartz countertops are cut with precision, which makes the edges seamless and the details crisp.
How Much Should You Pay? Quartz Grade vs. Budget
There’s a quartz countertop for every budget. It all depends on how long you plan on staying in your home, how much use your countertops will get, and how much you’re willing to spend. Here’s a general breakdown of pricing by grade:
| Quartz Grade | Average Cost per Sq. Ft. (Installed) | Best For | Long-Term Value |
| Level 1 (Basic) | $50 – $70 | Rentals, budget remodels | Moderate, Affordable, Less Unique |
| Level 2–3 (Mid-Range) | $70 – $100 | Family kitchens, standard upgrades | High, Best cost-to-durability ratio |
| Level 4–7 (Premium / Exotic) | $100 – $200+ | Luxury builds, designer kitchens | Exceptional, Becomes a focal point |
When Is Premium Quartz Worth It?
- Forever Home: If you’re planning to stick around, go for a durable, beautiful quartz countertop that you’ll enjoy for years.
- Selling Soon?: Mid-range quartz tends to offer the best return on investment without blowing your budget.
- Rentals or Secondary Spaces: An entry-level quartz countertop makes more sense for spaces with lighter use.
How to Identify Genuine Quartz Quality When Buying
Choosing the right quartz countertop isn’t just about picking a pretty design; you also want to ensure it’s made from quality, durable materials. Here’s how to verify quartz quality before committing to your purchase:
Questions to Ask Your Supplier
Don’t be afraid to ask your supplier the following:
- What grade is this quartz, and why?
- Is it a 2cm or 3cm slab?
- Has it been pre-sealed, or will it need sealing after installation?
- Where was this particular quartz sourced from?
A trustworthy supplier should be able to provide you with the answers you need — and documentation if necessary.
Simple Physical Tests You Can Perform
You don’t need to be an expert to check if your quartz countertops are up to snuff. Here are a few tests you can do:
- Scratch Test: Genuine quartz is tough. If your key or coin leaves a mark, it’s either not real or a lower grade.
- Water Absorption Test: Drop a bit of water on the surface. If it darkens quickly, it’s porous and might be a lower-grade option.
- Heat Test: Place a hot pot on the surface. Real quartz can handle heat better than lower-quality alternatives.
Watch Out for Counterfeit Quartz Lookalikes
Some stores try to sell laminate or fake quartz as the real thing. If it’s too smooth or perfect, it might be engineered quartz, not natural. Always double-check for authenticity.
Conclusion
Picking the right quartz countertop is about more than just style. It’s an investment in how your kitchen will look and how well it’ll perform over time. Whether you go for a basic, entry-level quartz or a bold, exotic design, make sure the countertop fits both your needs and your budget. Mid-range quartz countertops typically offer the best balance between cost and performance, while high-end options can give your space a truly luxurious feel. By understanding the grading system, you’ll ensure you’re making a smart investment, not just paying for a pretty face.
