How to Choose the Right Countertop Material: Quartz, Granite, Quartzite & More

Most homeowners walk into a countertop decision having already narrowed it down to two options. By the time they leave a showroom, many of them are looking at a third material they had never seriously considered. 

With over 30 years of helping homeowners and contractors in Camas, Southwest Washington, and the greater Portland area find the right surface, we have seen this play out more times than we can count. This post walks through the most common countertop materials, breaks down the differences between them, what each one actually does in real daily use, and how to figure out which one belongs in your project.

Natural Stone: Granite, Quartzite, and Marble

Let’s start with natural stone. These three materials are what most people picture when they think of natural stone countertops. They come out of the ground, get cut into slabs, and no two are exactly alike. That said, they perform very differently, and choosing based on looks alone is how homeowners end up with regrets.

Granite

Granite is the most cost-efficient natural stone for most projects. It is a coarse-grained igneous rock composed mostly of quartz, feldspar, and mica, which gives it a Mohs hardness of 6 to 6.5. In other words, that hardness makes it genuinely durable, heat resistant, and a solid choice for outdoor kitchen applications. 

Colors span the full spectrum, including deep blacks with satin finishes that are difficult to replicate in any engineered material. For buyers who want natural stone at a more accessible price point, granite is usually the starting point.

Quartzite

Quartzite is one of the hardest natural stones we carry, typically measuring around 7 to 8 on the Mohs hardness scale. It forms when quartz-rich sandstone is subjected to intense heat and pressure, creating a dense metamorphic stone composed of roughly 90 to 99 percent quartz.

The reason it has become so popular is the combination of a soft, marble-like visual and serious performance behind it. Many quartzite slabs offer creamy whites and flowing veins that look delicate but scratch and heat far better than marble does. The tradeoff is price. Quartzite sits at the higher end of the natural stone range, and you should expect to pay accordingly.

Marble

Marble has been used in interiors for centuries, and its warmth, timeless beauty and veining are genuinely hard to match. It is heat resistant and can work in outdoor applications. However, marble is softer and more porous than both granite and quartzite, which means it etches from acidic contact, scratches more easily, and requires sealing every 6 to 12 months depending on use, compared to granite which most owners reseal every 1 to 2 years.

In a busy kitchen where wine, lemon juice, and tomato sauce are part of daily life, that maintenance reality matters. We often recommend a honed finish for marble rather than a high-gloss polish, because small surface scratches are far less visible on a matte surface. Marble is a strong choice for lower-traffic applications like bathroom vanities, laundry rooms, and wet bars where aesthetics lead and daily wear is limited. In terms of cos, Marble varies from mid-range to quite expensive depending on the marble.

Quartz: What It Actually Is and Where It Works

The most common question we hear in our showroom is: “What is the difference between quartz and natural stone?” It is a fair question because the terminology causes genuine confusion.

Quartz countertops are an engineered product, not a mined stone. The main ingredient is ground quartz crystal, roughly 94% of the slab, combined with polyester resins for binding and pigments for color. Some designs include recycled glass or metallic flecks. Because the resins fill every pore, quartz is nonporous and never needs sealing. It is also highly consistent, which makes it predictable to work with and install.

The appeal for most buyers comes down to color options and low maintenance. Because quartz is manufactured, any color is achievable, and the whites and light tones that are currently popular are easier to source consistently in quartz than in natural stone.

Quartz Limitations

Where quartz has real limitations, we say so clearly. First, heat. Most manufacturers rate quartz surfaces to 300 to 400 degrees Fahrenheit, but sudden temperature change is the bigger risk. A pan pulled directly from a 450-degree oven and set on a cold quartz surface can cause cracking. The resin content that makes quartz nonporous is also what makes it vulnerable to thermal shock. Always use a trivet.

Second, quartz is not suitable for outdoor use. It is not UV stable, meaning any sustained sun exposure will cause fading and voids most manufacturer warranties. If you are planning a covered patio or outdoor kitchen, this rules quartz out entirely. Granite or quartzite are the right materials for that application.

Pricing on quartz varies significantly, and that range has as much to do with brand and color as it does with the material itself.

Less Common Materials Worth Knowing

Not every project calls for the most popular options. For buyers looking at specialty applications or a specific aesthetic, these materials come up regularly in our showroom.

Soapstone 

Soapstone is a metamorphic rock composed primarily of magnesium-rich talc, meaning it is a natural stone that has been transformed over time by intense heat and pressure deep within the earth, creating a denser and more stable material. 

It has a soft, tactile quality and ranges from light greens and grays to near-black. It is genuinely beautiful in the right space. It is also soft, which means it scratches. We are direct with every customer who asks about soapstone: if you want a surface that stays pristine, this is the wrong choice. If you love the look and accept that patina and minor surface marks are part of owning it, soapstone delivers something no other material does. Cost tends to fall in the mid-to-high range.

Dolomite

Dolomite is a natural stone that looks similar to marble, typically white or gray with veining, but offers better durability and resistance to etching. It is softer than granite but harder than marble, and it resists etching more reliably. We specifically work with satin-finish dolomites to reduce etching problems that come with polished surfaces. Dolomite is generally more affordable than high-end granites or quartzites, making it a practical option for buyers who want a marble aesthetic without the full marble maintenance commitment.

Limestone and Travertine

Both are sedimentary stones that we see most often in flooring, wall cladding, shower surrounds, and fireplace surrounds. Both are porous, require sealing at least once a year, and are softer than granite, quartzite, or quartz, which means they scratch more readily under daily countertop use. We do not typically recommend either for high-traffic kitchen countertop applications, but for the right aesthetic in lower-wear applications, they can be appropriate. 

Pricing generally falls in the lower-to-middle range.

How to Choose the Right Material for Your Project

The material that is right for you depends on three things: how you actually use the space, how much ongoing maintenance you are willing to do, and what your budget looks like.

Here is how the main options break down:

• Granite: Natural stone performance, lowest maintenance obligation, best natural stone price point
• Quartzite: Marble-like visuals with better scratch and heat resistance, at a higher cost
• Quartz: Widest color selection, no sealing ever, indoor use only; not suitable for outdoor applications or direct heat
• Marble: Genuinely rewarding in lower-use spaces; go in with clear eyes on the sealing schedule (every 6 to 12 months) and etching risk
• Soapstone / Dolomite / Limestone: Right for specific aesthetics and applications; ask us in person if one of these is on your radar

If a material is a wrong fit for your project, we will tell you before you buy.

At American Marble & Granite, we carry more than 400 slabs in stock, including a hand-selected range of quartz and natural stone, plus over 800 remnants for smaller projects. Materials are priced by the square foot, which means you pay only for what your project actually uses.

Our in-house designers and showroom team are here to walk you through the options in person so you can see the slabs, compare your choices side by side, and make a decision you feel good about.

See the Materials in Person Before You Decide

Reading about countertop materials gets you most of the way there. Seeing them in person closes the gap. Color, movement, and finish all read differently under a showroom light than they do on a screen, and for a surface you will look at every day, that difference matters.

Frequently Asked Questions

What is the most durable countertop material for a busy kitchen?

Quartzite is the hardest natural stone option, rating 7.5 to 8.5 on the Mohs scale, making it highly resistant to scratches and heat. Granite is a close second and typically more affordable. Quartz is also a strong performer for indoor kitchens, with no sealing required, though it cannot handle sudden heat exposure the way natural stone can.

What is the difference between quartz and quartzite?

Quartz is an engineered product made from ground quartz crystals, resins, and pigments. Quartzite is a natural metamorphic rock formed from sandstone under heat and pressure. Quartzite requires sealing and has natural variation slab to slab. Quartz never needs sealing and is more consistent in color and pattern. Both are strong performers, but they are completely different materials.

How often does a natural stone countertop need to be sealed?

It depends on the material. Granite typically needs resealing every 1 to 2 years. Marble requires sealing every 6 to 12 months, more often in a high-use kitchen. Quartzite falls closer to granite on the sealing schedule. Quartz never needs to be sealed because the manufacturing process makes it nonporous.

Can I use quartz countertops in an outdoor kitchen? 

Standard indoor quartz is usually not recommended for outdoor kitchens because it is not fully UV stable. Long-term sun exposure can cause fading, discoloration, and may void the manufacturer’s warranty. Some brands offer outdoor-rated quartz, but for most outdoor kitchens and covered patios, granite and quartzite are the safer long-term choice because they handle sun, moisture, and temperature changes better.
