Quartzite gives you the soft, marble-like movement many people want with hardness that exceeds most granite. TopStone Granite fabricates and installs natural quartzite countertops for kitchens, islands and baths across Baltimore and the surrounding region.
Quartzite is also one of the most mislabeled stones in the trade. Some slabs sold under the name are softer dolomite or marble that etch from a squeeze of lemon, so knowing how to check a slab protects your investment.
With 15+ years of experience and 650+ completed jobs, we know how hard natural stone cuts, chips and wears. We are licensed and insured under MHIC #145977.
Quartzite starts as quartz-rich sandstone. Over millions of years, heat and pressure fuse the sand grains into a dense, crystalline stone that is quarried and polished like granite.
Because it is so hard and stable, quartzite works in nearly any countertop application:
Each project includes templating, fabrication, edge finishing, sink and cooktop openings and installation. On veined quartzites, we lay out the pieces so the movement flows across seams. See our seam matching page for how that planning works.
Quartzite is a geological definition, not a marketing term. Trade names, on the other hand, are chosen to sell, and a few popular "quartzites" are actually dolomite or dolomitic marble.
Those stones can be lovely, but they are softer and react to acids, so they need marble-style care at a quartzite price. Ask for a small sample or an offcut from the same lot and run two simple checks before you sign.
Quartz rates about 7 on the Mohs scale, harder than ordinary glass at about 5.5. Press a sharp corner of the sample firmly across a glass tile or bottle.
Then wipe the glass and run a fingernail over the mark. A true scratch you can feel points to quartzite, while a powdery line that wipes away means the stone is softer than glass.
Place a few drops of lemon juice or white vinegar on a polished area of the sample. Wait at least 10 to 15 minutes, since dolomite reacts more slowly than marble, then rinse and dry.
A dull, slightly rough spot means the stone contains calcite or dolomite. True quartzite should look unchanged. Always test a sample, never the face of a slab you have not purchased.
Stone names travel from quarry to exporter to distributor, and each step can rename a material. Dolomite is often sold as "soft quartzite" or "hard marble," which blurs the line further.
Most mislabeling is a naming habit rather than fraud, but the cost falls on you either way. For a broader look at engineered quartz versus natural quartzite, read quartz vs. quartzite.
Quartzite colors run from creamy whites and soft grays to greens, blues and rich golds. Every slab is unique, and lots from the same quarry can look noticeably different, so plan to see the actual slab. Lighting matters too, since warm and cool bulbs shift how cream and gray tones read in your home.
Taj Mahal is the most searched quartzite name and is generally considered true quartzite. Quarried in Brazil, it shows a creamy white to soft beige background with gentle gold and taupe veining.
It pairs well with warm wood cabinets, brass hardware and white oak floors. Slabs vary from lot to lot, so ask to approve the exact slab for your job.
White Macaubas shows crisp white with linear gray and blue-gray veins. Sea Pearl has a gray and white background with soft, wavy movement and hints of green.
Be careful with Super White. It is sold as quartzite, but many slabs behave like dolomite and etch from acids. Test it before you commit.
Quartzite also comes in saturated colors that few other natural stones offer. Azul Macaubas, a rare blue quartzite from Brazil, is one of the best known, and it is priced accordingly.
Colorful quartzites often work best as a single statement piece, such as an island or bar top, paired with a quieter stone or quartz on the perimeter.
Quartzite usually costs more than granite, and the slab price is only part of the reason. Its hardness makes every fabrication step slower:
The slab itself also carries a premium. Popular white and warm quartzites are in steady demand, and supply from individual quarries is limited, so prices follow the market more than with engineered quartz.
Simple eased or beveled edges are often the smart choice on quartzite. Compare options in our edge profiles guide, and see typical installed ranges in our countertop cost guide. To weigh quartzite against granite, quartz and marble, visit our countertop materials guide.
Quartzite's strength is also what makes it demanding in the shop. The full sequence from templating to installation day is on our process page, and these are the steps where quartzite gets extra care:
Outdoors, quartzite holds its color in the sun, but freeze-thaw weather can push water into any porous stone. A good seal and a slight slope or overhang that sheds water help an outdoor top last.
True quartzite does not etch from kitchen acids and handles heat well. It is still a natural stone with some porosity, and absorbency varies widely between slabs and even within a single slab.
We recommend sealing quartzite at installation and checking it with a water drop test every few months. If the stone darkens within a few minutes, it is time to reseal through our stone sealing and polishing service.
For daily cleaning, use mild dish soap or a pH-neutral stone cleaner. If your stone tested as dolomite, treat it like marble: wipe acids quickly and use coasters. If a quartzite edge chips, our countertop repair team can usually fill and polish it.
Quartz countertops are engineered from crushed quartz bound with resin and pigment. Quartzite is a natural metamorphic stone quarried in slabs. Our quartz vs. quartzite guide compares them in detail.
Usually. Quartzite's absorbency ranges from almost nothing to fairly thirsty, sometimes within one slab, so we treat sealing as the default. Once it is installed, a few drops of water left for several minutes tell you when the protection is wearing thin.
For many homeowners, yes. It offers a soft, warm marble look with far better resistance to etching, heat and scratching than marble. The trade-offs are a higher price, the need for sealing and natural variation that means you should approve your actual slab.
Generally, yes. Quartzite is made almost entirely of quartz, while granite also contains softer minerals like feldspar and mica. That hardness is great for durability but makes quartzite slower and more costly to fabricate.
True quartzite resists scratches from knives, pots and everyday use better than almost any natural stone. It can chip on edges and corners if struck by heavy cookware, because hard stone is also somewhat brittle. Small chips can usually be filled and polished to blend.
Yes, true quartzite is one of the better natural stones for outdoor use because sunlight does not fade it. Seal it well before the first winter, since water that freezes inside any porous stone can cause damage. Recheck the seal each spring.
Send us the name of the quartzite you are considering or bring a sample to our shop, and we will talk through how it will perform in your space. Ask us to help you check a slab before you buy.
