Not all stone is the same. Granite behaves nothing like marble. Travertine needs different care than slate. If you’re choosing stone for a kitchen, floor, or patio — this is what you actually need to know before you spend the money.
Walk into a stone supplier, tell them you want “natural stone,” and you’ll get ten questions back. Which one? For what? Inside or outside? Countertop or floor? It’s not them being difficult — it’s genuinely a complicated choice, because each type of natural stone has a completely different character. Some are nearly indestructible. Some look stunning but need coddling. Some are perfect for kitchens; others would be a disaster there.
This guide runs through all eight of the most commonly used types of natural stone, covering what each one actually is, where it performs well, where it doesn’t, and roughly what you should expect to pay. No filler, just the practical stuff.
Granite
The workhorse of the natural stone world — and still the most used for good reason
- Hardness: 6–7 Mohs
- Porosity: Low
- Cost (sq ft): $40–$200
Granite is an igneous rock — formed from cooled magma deep underground. According to Geological Society of London, igneous rocks like granite develop exceptional density and durability due to their formation under extreme heat and pressure.
That origin gives it exceptional density and hardness. It is genuinely tough. You can set a hot pan on it, you can drag a cast iron skillet across it, and it shrugs it off. For kitchens especially, granite has been the dominant countertop choice for decades, and that’s largely because it earns it.
The look varies enormously by origin. Indian granite tends toward black and grey. Brazilian granite is where you get the dramatic movement — the sweeping waves of color that have become increasingly popular. Norwegian granites lean cool and speckled. There’s really a granite for almost any aesthetic.
Best Used For: Kitchen countertops, outdoor kitchens, high-traffic flooring, bathroom vanities, fireplace surrounds
Avoid For: Spaces where you want a very uniform, non-speckled look — granite’s natural variation isn’t for everyone
Heat-Resistant, Scratch-Resistant, Seal Yearly, Indoor & Outdoor
Marble
- Hardness: 3–4 Mohs
- Porosity: Medium–High
- Cost (sq ft): $50–$250+
Marble starts as limestone and gets transformed under intense heat and pressure. That process recrystallizes the calcium carbonate into the fluid veining that makes marble so immediately recognizable. Carrara white with its grey veining. Calacatta with its bold, dramatic movement. Nero Marquina — solid black. The material has been used in the finest buildings on earth for thousands of years, and there’s a reason for that.
The reality check: marble is softer than most people expect, and it etches. Acids — lemon juice, vinegar, wine, coffee — will dull the surface if left sitting. Scratches happen. That’s not a reason to avoid it, but it is a reason to go in with your eyes open. Many people love the way marble ages and develops patina. Others find the maintenance stressful. Know which camp you’re in before you commit.
Best Used For: Bathroom vanities, shower surrounds, low-traffic floors, fireplace surrounds, decorative applications
Think Twice For: Busy family kitchens — the etching and staining risk is real. Not impossible, just higher maintenance than most people plan for.
Etches with Acid, Seal Regularly, Luxury Aesthetic, Ages with Character
Marble Maintenance Reality Check
Honed marble shows etching less than polished marble — so if you want marble in the kitchen, go honed. You’ll still see marks over time, but they’re far less dramatic and blend into the surface rather than standing out as shiny spots.
Limestone
- Hardness: 3–4 Mohs
- Porosity: Medium
- Cost (sq ft): $8–$50
Limestone forms from compressed marine sediment — shells, coral, algae — over millions of years. That origin is often visible in the stone: fossils, shell fragments, organic marks that give each piece a kind of quiet history. Tones are mostly warm — creams, buffs, honey, soft grey — and the surface has a matte, organic warmth that polished stones don’t have.
It’s particularly popular for flooring, especially in traditional UK homes and French farmhouse-style interiors. Honed limestone floors with wide grout joints and some plant life through them — that’s a classic for a reason. It’s softer than granite or quartzite, so it does need sealing, and it will show some wear over many years. Some people find that appealing; it looks genuinely old in the best possible way.
Best Used For: Interior flooring, bathroom floors, garden patios (frost-resistant grades), hallways, feature walls
Watch Out For: Acid sensitivity similar to marble — avoid vinegar cleaners. Not all grades are frost-proof, so confirm before using outside in cold climates.
Good Value, Warm Tones, UFH-Compatible, Needs Sealing
Sandstone
- Hardness: 6–7 Mohs
- Porosity: Medium–High
- Cost (sq ft): $5–$30
Sandstone is exactly what it sounds like — sand grains cemented together by minerals, typically quartz or calcite, over geological time. Indian sandstone is the variety most US and UK homeowners encounter, and it dominates the outdoor paving market. The natural riven surface — slightly uneven, textured — gives it outstanding grip even when wet, which is why garden patios and pathways are its primary territory.
Colors go from buff and honey yellow through autumn brown, rusty orange, and cool grey-blue. The warm tones are the most popular, particularly in UK gardens where buff sandstone and red brick are an almost universally pleasing combination. Indoors, it works well in conservatories and hallways — but it’s porous, so sealing matters more here than almost any other stone type.
Best Used For: Garden patios, pathways, driveways, pool surrounds, exterior cladding, rustic interior floors
Worth Knowing: Porosity varies a lot by origin and grade — Indian sandstone paving needs sealing more regularly than denser UK varieties. Always seal before use outdoors.

Quartzite
- Hardness: 7 Mohs
- Porosity: Low–Medium
- Cost (sq ft): $60–$200+
Quartzite is sandstone that’s been subjected to extreme heat and pressure underground, fusing all the individual sand grains into an interlocked crystalline mass. What comes out is one of the hardest natural stones used in homes — harder than marble, harder than limestone, resistant to scratching and heat in a way softer stones simply aren’t.
The appeal is the look: quartzite develops the sweeping veining and movement you’d normally associate with marble, but without marble’s vulnerability to etching and scratching. Super White, Taj Mahal, Sea Pearl — these are all quartzite varieties that get compared to marble constantly. One catch worth knowing: mislabeling is rampant in this category. A lot of stone sold as quartzite is actually marble or dolomite. Do a scratch test before buying anything expensive.
Best Used For: Kitchen countertops, bathroom vanities, statement flooring, fireplace surrounds
Key Watch-Out: Always verify you’re buying true quartzite. Drag a glass tile across a sample — quartzite scratches the glass, not the other way around.
Hardest Natural Stone, Heat-Resistant, Verify Before Buying, Marble-Like Look
The Quartzite Mislabeling Problem
Industry estimates suggest a significant portion of stone sold as quartzite in the US is actually softer stone in disguise. This matters enormously for kitchens. A reputable supplier will have geological certifications. If they can’t produce them, that’s worth knowing before you buy.
Travertine
The Mediterranean classic — warm, honeyed, a little high-maintenance. Sedimentary Rock · Italy, Turkey, Iran, Mexico
- Hardness: 3–4 Mohs
- Porosity: High
- Cost (sq ft): $15–$80
Travertine forms around hot springs and geothermal vents, built up layer by layer from dissolved calcium carbonate. That formation process creates its most distinctive feature: natural holes and voids throughout the stone’s surface. Travertine tiles are sold either filled (the holes are filled with grout or resin before installation) or unfilled, which gives a more rustic, textured look that collects character — and grime.
The warm, honeyed cream and walnut tones are immediately identifiable. This is the stone you see on Tuscan farmhouse floors, around Arizona pool decks, in Spanish Colonial architecture across California and Texas. It’s genuinely warm and beautiful. What it isn’t is easy — travertine needs filling, sealing, and careful cleaning, and it etches from acids like marble does.
Best Used For: Pool surrounds, spa bathrooms, Tuscan-style floors, exterior cladding, low-traffic hallways
Before You Buy: Decide filled or unfilled upfront — it affects grout choice, maintenance, and the final look significantly. Unfilled is more characterful but harder to keep clean.
Warm Honey Tones, High Porosity Filled or Unfilled Mediterranean Style
Slate
The practical choice that doesn’t get nearly enough credit. Metamorphic Rock · Wales, India, Spain, Brazil, USA
- Hardness: 5–6 Mohs
- Porosity: Very Low
- Cost (sq ft): $5–$40
Slate is a fine-grained metamorphic rock that splits naturally into flat layers — which is why it’s been used for roofing and flooring for centuries. It’s a denser, tighter stone than most people realize. Very low porosity means it doesn’t need sealing as frequently as limestone or travertine. The cleft surface — that natural, slightly uneven texture — is slip-resistant and hides scratches surprisingly well.
Colors are mostly cool and earthy: dark grey, charcoal, mottled green-grey, rusty brown in some Indian varieties. It’s not a glamorous stone in the way marble is, but it’s honest. A slate floor in a mudroom, a kitchen, or a garden room just works. It takes what’s thrown at it and keeps looking good. It tends to be underrated by people who’ve never lived with it, and quietly loved by everyone who has.
Best Used For: Kitchen floors, mudrooms, bathrooms, outdoor steps, roofing, garden rooms, heavy-use areas
Worth Knowing: Some slate varieties flake or delaminate over time — particularly cheaper Indian grades. Welsh and Spanish slates are much more stable long-term.
Very Low Maintenance, Non-Slip, Frost-Proof Underrated
Onyx
The one you use when making a statement is the whole point, Sedimentary Stone · Iran, Pakistan, Mexico, Brazil
- Hardness: 3–3.5 Mohs
- Porosity: High
- Cost (sq ft): $80–$400+
Onyx is the most visually dramatic natural stone you’re likely to encounter. It forms from dissolved limestone deposited by flowing water, often inside caves, and develops extraordinary translucency — hold a backlit onyx slab up and it genuinely glows. The color range runs from white and honey through deep green, amber, and black. The banding and movement are unlike anything else in the natural stone world.
Use it for drama, not function. Onyx is soft, fragile, highly porous, and expensive. It scratches easily, it stains, it chips. What it does do is look absolutely extraordinary as a backlit bar top, a feature wall panel, a reception desk. Used in small amounts where it’s protected and appreciated for its looks, it’s genuinely one of the most special materials available. Used as a kitchen countertop — it’ll be scratched and stained within a month.
Best Used For: Backlit feature walls, bar tops, powder room vanities, decorative panels, luxury reception areas
Be Realistic: This is a delicate stone. It’s for beauty, not for everyday function. Protect it with glass or resin coating if it’ll see regular contact.

| Travertine | Sedimentary | ● Medium | High | Every 1–2 yrs | Pools, spa rooms | $15–$80/sf |
| Marble | Metamorphic | ● Softer | Med–High | Every 6–12 mo | Bathrooms, low-traffic | $50–$250+/sf |
| Onyx | Sedimentary | ● Softest | High | Frequently | Feature walls, décor | $80–$400+/sf |
So — Which Type of Natural Stone Should You Choose?
There isn’t a single best answer here, which is why the question gets asked so often. Choosing the right supplier matters just as much as choosing the right material — working with a trusted source like Auresta Stones helps ensure quality, proper grading, and long-term performance.
If you need → Kitchen countertops
Granite or Quartzite
Heat-resistant, hard enough for daily use, holds up over years. Granite is more affordable; quartzite gives you that marble look with better durability.
If you need → Bathroom vanity
Marble, Quartzite, or Limestone
Lower traffic means softer stones are more viable here. Marble is beautiful in bathrooms. Limestone works well too. Just seal properly and avoid harsh cleaners.
If you need → Garden patio
Sandstone or Slate
Both are slip-resistant, frost-tolerant in the right grades, and age well outdoors. Indian sandstone is the UK and US patio standard. Slate works brilliantly for steps and paths.
If you need → Interior flooring
Limestone, Slate, or Granite
Limestone for warmth and a classic feel. Slate for high-traffic areas where you want near-zero maintenance. Granite for statement floors that will outlast the building.
If you need → A statement feature
Onyx or Marble
If the application is low-traffic and purely visual — a backlit panel, a powder room, a fireplace surround — this is where you use the beautiful fragile stuff.
If you need → Pool surrounds
Travertine or Sandstone
Both handle wet conditions, both stay relatively cool underfoot in sun. Travertine is the traditional choice. Sandstone is cheaper and just as effective in the right grade.
One Rule Above All Others
Always see the full slab in person before you commit. Sample tiles are basically useless for understanding what a stone will look like at countertop or floor scale. The movement, color variation, and energy of a slab only reveals itself when you’re standing in front of the real thing.
FAQs
The eight you’ll most commonly encounter are granite, marble, limestone, sandstone, quartzite, travertine, slate, and onyx. Each has different hardness, porosity, and ideal uses — which is why the same answer doesn’t fit every project. Granite and quartzite for kitchens. Marble and limestone for bathrooms and floors. Sandstone and slate outdoors. Onyx when you want something extraordinary in a protected spot.
Slate, hands down. Very low porosity means it barely needs sealing, it doesn’t etch from acids, and its textured surface hides wear well. Granite comes second — it needs sealing occasionally but otherwise shrugs off daily kitchen life with minimal fuss. The high-maintenance end of the spectrum is onyx, then travertine, then marble.
Generally yes, particularly in kitchens and bathrooms. Natural stone countertops and quality stone flooring are consistently cited in US and UK property surveys as features buyers value. The caveat is quality — poorly installed or maintained stone can be a negative rather than a positive. Done well, it tends to age better than most alternatives and holds its appeal longer than trends-driven materials.
Yes, with some caveats. Most stone needs to be sealed properly before use in wet areas, and polished finishes are a slip risk when wet. In bathrooms, go for a honed or textured finish. Marble, limestone, and travertine all look stunning in bathrooms. Slate is the most practical. Whatever you choose, use epoxy grout in shower applications — standard grout will absorb water and develop mold at the joints over time
Sandstone and slate are the most affordable entry points, often from $5–$15 per square foot for standard grades. Limestone is next — entry-level Turkish limestone is very competitively priced. At the other end, premium quartzite, exotic marble, and onyx can run well past $200 per square foot. For most homeowners, mid-range granite or limestone gives the best balance of quality, look, and price.
Many types, yes — but not all. Sandstone and slate are the most widely used for outdoor applications and handle freeze-thaw cycles well in appropriate grades. Granite is nearly indestructible outside. Limestone and travertine can be used outdoors but you need to specify frost-resistant grades if you’re in a cold climate. Marble and onyx are not suited for outdoor use — they’re too soft and porous to handle exposure.
