Choosing between marble vs granite is rarely just a color decision. It affects fabrication, installation, maintenance, and how the finished project ages. At Marble Supply Co., the export brand of PFM Imp. & Exp. Co., Ltd., we work with contractors, designers, and project owners who need to compare materials before they commit. Founded in 2008, the company is a Guangzhou-based trading company with a showroom and export office about 25 minutes from the airport, supported by partner fabrication in Yunfu City and Shuitou City, as described on the company's website. This guide compares marble versus granite across countertops, flooring, and facades so you can specify the right stone with fewer surprises.
Marble vs granite at a glance
The difference between marble and granite starts with geology. Marble is a metamorphic stone formed from limestone; it is prized for veining, movement, and the ability to be book-matched. Granite is an igneous stone composed mainly of quartz and feldspar; it is generally harder, denser, and more uniform in appearance. Both are natural materials, so batch variation is normal. The table below summarizes the trade-offs project teams ask about most often.
| Property | Marble | Granite |
|---|---|---|
| Hardness and abrasion | Softer, typically Mohs 3-5; scratches more easily and needs careful handling on high-traffic surfaces. | Harder, typically Mohs 6-7; more resistant to scratching and abrasion in busy areas. |
| Porosity and absorption | Moderate to high porosity; sealing is important, especially for light colors and honed finishes. | Generally low porosity; denser and less absorbent, though some varieties still benefit from sealing. |
| Heat resistance | Moderate; sudden heat can damage polish or cause thermal stress in some marbles. | High; handles heat better, which is useful for kitchen work zones. |
| Acid resistance | Low; acids etch the surface. Lemon, vinegar, wine, and acidic cleaners can leave dull marks. | Generally high; most granites resist acids well, though some varieties can react. |
| Typical applications | Interior walls and floors, vanities, fireplaces, columns, medallions, mosaics, moldings, decorative features. | Countertops, high-traffic flooring, stairs, exterior cladding, wet areas, and durable architectural surfaces. |
| Maintenance | Seal regularly, clean with pH-neutral products, wipe spills quickly, and expect a patina over time. | Seal less frequently, clean with mild soap and water, and avoid abrasive pads on polished finishes. |
| Cost drivers | Color rarity, quarry availability, veining consistency, thickness, finish, fabrication complexity, and freight. | Color availability, grain uniformity, thickness, finish, edge details, installation method, and shipping distance. |
Where marble wins
Marble wins when the design intent depends on character. No two slabs are identical, and the stone’s veining can define a lobby, bathroom, fireplace, or feature wall. For interior work, marble is often the preferred choice for wall cladding, floor inlays, vanity tops, stair treads, columns, and decorative elements such as medallions and mosaic patterns. It also takes well to book-matching, where adjacent slabs are mirrored to create a dramatic symmetrical pattern.
Marble is also easier to fabricate into complex profiles. Moldings, carved fireplaces, fountains, and sculptures are traditionally produced in marble because it holds detail and can be shaped with hand and CNC tooling. In residential and hospitality projects, the stone’s softness underfoot and reflective polish are part of the luxury experience. For buyers seeking a white marble with a known supply route, Tasso White marble is supplied through a Tajikistan quarry partnership.
The trade-off is that marble is not the lowest-maintenance choice. It rewards projects where patina is acceptable, where spills are managed, and where the surface is not exposed to heavy acid or abrasive traffic.
Where granite wins
Granite wins when durability and predictability matter most. Its hardness makes it a practical choice for kitchen countertops, commercial flooring, stair treads, and high-use circulation areas. Granite also performs well outdoors, where it resists weathering, thermal cycling, and many pollutants better than acid-sensitive marble. For facades, exterior paving, and cladding in busy urban environments, granite is often the safer specification.
Granite’s appearance is usually more uniform than marble’s. That can be an advantage in large projects where consistency across floors, walls, and counters is critical. It is available in a wide range of colors and finishes, from polished and honed to flamed and brushed. Granite is also generally more forgiving during installation because it chips and scratches less easily, although it still requires proper handling and substrate preparation.
For projects that need a dark, durable stone, black granite is often specified where black marble would be too acid-sensitive. However, be careful with names: “black granite” may be a true granite, a basalt, or another fine-grained dark stone. The geological name matters less than the tested performance for your application.
Marble vs granite countertops: the acid test
In kitchens, the marble vs granite countertops decision usually comes down to acid resistance. Marble is calcium carbonate based, so acidic foods and cleaners etch the surface. A lemon slice, vinegar, wine, or tomato sauce left on marble can leave a dull mark that requires refinishing. Granite is generally more acid-resistant and better able to handle daily kitchen activity without visible etching.
That does not mean marble is impossible in a kitchen. Many designers specify marble for perimeter counters, islands used for serving, or bathrooms where acid exposure is lower. A honed finish can make etching less obvious than a high polish. Regular sealing helps with staining, but it does not prevent acid etching. If the client wants a marble look with fewer maintenance demands, a granite or quartz alternative may be the more practical recommendation.
The black marble vs black granite comparison is a good example. Black marble such as Nero Marquina-style material offers dramatic white veining and a high-contrast look, but it can show scratches, etch marks, and dust. Black granite or dark basalt sold as granite is usually harder and more acid-resistant, but it may be more uniform. Specify the finish, thickness, edge profile, and sink cutouts early, because these details affect both appearance and fabrication cost.
Marble vs granite for flooring and facades
For flooring, marble is often used in lobbies, bathrooms, and formal interiors where appearance is the priority. It should be protected from grit and heavy foot traffic, and it needs a maintenance plan that includes sealing and pH-neutral cleaning. Granite is usually the better choice for shopping centers, airports, commercial corridors, and exterior walkways because it resists abrasion and staining more effectively.
For facades, the marble vs granite decision depends on exposure. Marble can be used on protected facades, interior atriums, and decorative wall panels, but acid rain and pollution can dull or etch exposed surfaces. Granite is generally more suitable for exterior cladding, especially in coastal, industrial, or high-rainfall environments. Marble Supply Co. works with four facade fixing systems — Back Bolt System, Slotted Dry Hanging System, Glued Wall and Flooring System, and Single Point Hanging Wall Cladding System — plus Architectural Waterjet Technology, a cutting and inlay technology. The right system depends on stone type, panel size, substrate, wind load, and local building codes.
Thermal movement also matters. Dark stones can absorb more heat, so large exterior panels need proper anchors, joints, and ventilation. Whether the project uses marble or granite, the facade design should be reviewed by an engineer and coordinated with the stone supplier early.
How to specify either stone from a supplier
Start with samples and test data, not just photos. Marble Supply Co. offers free samples for marble, granite, and mosaic. Freight is paid by the buyer and refunded on order, and samples are usually ready in 1-3 days. For project approvals, request a sample that represents the actual batch range, including veining and color movement for marble and grain variation for granite.
MOQ is usually 50 square meters, though complex or special-order items may differ. A complete specification should include stone name, color, finish, thickness, tile or slab dimensions, edge details, tolerances, installation method, and expected application. Shop drawings or setting drawings are essential for stairs, columns, medallions, mosaics, fireplaces, and facade panels because they show how each piece will be cut, labeled, and installed. Confirm who will produce and approve those drawings before production begins.
Business terms are straightforward. Payment is 30% T/T advance plus 70% before shipment. Shipping ports are Guangzhou and Shenzhen. Replies usually come within 24 hours, and Certificates available upon request. If the project requires fabrication, the company’s partner fabrication in Yunfu City and Shuitou City (as described on the company's website), while the Guangzhou showroom and export office are about 25 minutes from the airport.
There is no universal winner in marble vs granite. Marble offers unmatched character and works beautifully in interiors, decorative features, and lower-acid applications. Granite offers hardness, acid resistance, and predictability for countertops, high-traffic floors, and exterior facades. The right choice depends on where the stone will be used, how it will be maintained, and how much variation the design can accept. Match the material to the application, approve a real sample, and lock the specification before fabrication.
