Materials guide / Natural stone
Ten types of stone used in construction and architectural finishes are granite, marble, quartzite, alabaster, basalt, limestone, sandstone, travertine, slate and onyx.
They serve different purposes: some are selected for masonry or paving, while others are best considered for cladding and decorative interiors. The right choice depends on the application, exposure, finish, maintenance expectations and the performance of the actual stone being supplied.
10 types of building stone at a glance
| Stone | Typical applications | Key selection issue |
|---|---|---|
| 1. Granite | Floors, steps, countertops and exterior paving | Heavy; finish, joints and support need attention |
| 2. Marble | Interior floors, walls, stairs and feature surfaces | Acid etching and surface wear |
| 3. Quartzite | Countertops, floors and architectural surfaces | Material identification and fabrication complexity |
| 4. Alabaster | Interior feature panels, lighting and small details | Soft and sensitive; unsuitable for demanding surfaces |
| 5. Basalt | Paving, steps, landscape and exterior finishes | Dense material; exposure and finish still matter |
| 6. Limestone | Facades, masonry, interior floors and carved details | Acid sensitivity; durability varies by source |
| 7. Sandstone | Masonry, facade details, paving and landscaping | Cement type, bedding and moisture exposure |
| 8. Travertine | Interior floors, wall finishes and selected paving | Natural voids, filling and acid sensitivity |
| 9. Slate | Roofing, flooring, paving and wall finishes | Cleavage, thickness and source variability |
| 10. Onyx | Backlit walls, feature panels and decorative details | Fragile; acid- and scratch-sensitive |
Geologically, granite and basalt are igneous; limestone, sandstone and travertine are sedimentary; marble, quartzite and slate are metamorphic. Alabaster and architectural onyx need an additional material-identity check because commercial names do not always describe a single geological material. See the British Geological Survey’s introduction to rocks and minerals for the basic rock families.
1. Granite
Igneous stone
Granite is an igneous rock with an interlocking mineral structure, often showing visible quartz, feldspar and mica. It is a practical starting point for hard-wearing surfaces, but commercial granite varieties still differ in absorption, appearance and performance. Choose the specific stone and finish, not the name alone.
Typical uses: Interior floors and stairs; kitchen and vanity tops; exterior paving and architectural cladding where the product and fixing system are suitable.
Many varieties offer good wear resistance and a broad choice of colours, grain sizes and finishes. Matching stairs, floors and worktops can create a consistent material palette.
Polished granite can be slippery when wet. Heavy pieces require suitable handling and support; corners and cutouts still need careful detailing. Sealing requirements vary.
Before you order: Request the finish sample, thickness and edge details. For outdoor or wet floors, ask for slip and exposure-related evidence for the proposed finish, plus the installation specification.
2. Marble
Metamorphic stone
Marble forms when carbonate rock is changed by heat and pressure. Its veining and colour variation make it popular for villa interiors, hotel lobbies and decorative walls. Those patterns also make slab selection and layout approval important: a small sample cannot represent an entire room.
Typical uses: Interior wall panels, bathroom surfaces, floors, stairs, fireplace surrounds and selected countertops with appropriate care.
Distinctive natural veining, a wide range of colours and the possibility of bookmatched layouts. Different finishes can create either a reflective or a softer appearance.
Many marbles etch when exposed to acids such as lemon juice. Scratches and wear can become visible on polished surfaces. A sealer does not make marble acid-proof.
Before you order: Approve actual slab photographs, vein direction, joints and cutouts. Discuss expected wear and maintenance before choosing marble for a busy kitchen or commercial floor.
3. Quartzite
Metamorphic stone
Natural quartzite develops from quartz-rich sandstone through metamorphism. It is different from engineered quartz, which is a manufactured product made with mineral particles and a binder. Stone trade names can be confusing, so confirm what the offered slab actually is and obtain its own care and technical information.
Typical uses: Kitchen and vanity tops, flooring, stairs and wall cladding, subject to the stone, finish and installation requirements.
Many quartzites provide a hard surface with strong visual movement or softer, layered patterns. They can be worth comparing when a buyer wants natural stone for a demanding surface.
Hardness does not eliminate fractures, staining risk or vulnerable edges. Cutting, polishing and detailing complex pieces can be demanding. Do not assume every slab sold as quartzite performs alike.
Before you order: Ask the supplier to identify the material, any resin or mesh backing, the batch and suitable applications. Review cutouts, edge treatment and support with the fabricator.
Material reference: Natural Stone Institute: natural quartzite and engineered quartz.
4. Alabaster
Decorative stone / mineral material
Alabaster is a commercial name used for fine-grained translucent decorative materials, commonly gypsum and sometimes calcite. Its appeal is the way light passes through it. Because the name can cover different compositions, the material identity is especially important when specifying a panel or carved element.
Typical uses: Backlit interior panels, decorative screens, lighting features, carvings and selected furniture details.
Translucency and soft colour variation can create a striking focal point without a large quantity of material.
It is not a general-purpose structural or heavy-traffic stone. Scratching, moisture sensitivity and cleaning limitations depend on the material. Exterior and wet-area use require particular caution.
Before you order: Confirm whether the product is gypsum or calcite based. Approve a lit sample and discuss panel support, lighting heat, maintenance access and suitable cleaning products.
5. Basalt
Igneous stone
Basalt is a volcanic rock, usually dark and fine grained. The National Park Service describes basalt as a hard, dense rock. Solid basalt stone should not be confused with lightweight basalt-based insulation products: the name of the raw material does not give them the same properties.
Typical uses: Pavers, kerbs, steps, landscape features and cladding; crushed basalt can also be used as aggregate where specified.
Dark, relatively uniform tones can work well in contemporary landscapes. Appropriate basalt products can provide durable wearing surfaces.
Weathering, porosity and finish vary between sources. Do not assume a basalt tile is slip-resistant, frost-resistant or suitable for every chemical exposure without product evidence.
Before you order: Request absorption, wear and climate-relevant test information for the offered product. Confirm the paving build-up, drainage, joints and finish with the project team.
Material reference: National Park Service: basalt.
6. Limestone
Sedimentary stone
Limestone is a sedimentary carbonate rock, often selected for its quiet tones and consistent architectural character. Varieties range from relatively soft, porous stones to denser materials. This variation matters when moving from a sheltered interior wall to an exposed facade, entrance or terrace.
Typical uses: Architectural cladding, specified masonry, interior floors, stairs, window surrounds and carved architectural details.
A restrained colour palette and a surface that can be shaped into coordinated architectural elements. Suitable varieties can give a building a coherent, understated finish.
Acidic cleaners can damage carbonate stone. Porosity, abrasion resistance and weathering behaviour vary, so interior suitability does not automatically establish exterior suitability.
Before you order: For exterior use, ask for evidence relevant to local frost, moisture and salt conditions. Approve jointing, drip details and the cleaning method as part of the complete installation.
7. Sandstone
Sedimentary stone
Sandstone consists of sand-sized grains held together by natural mineral cement. That cement may include silica, calcite or iron compounds; it is not the same as adding construction cement to sand. Grain bonding and bedding help explain why two sandstones can weather very differently.
Typical uses: Building masonry, facade panels, paving, retaining-wall facing and landscape features, with application-specific selection.
Earthy tones, layered character and a range of textures can suit traditional and contemporary buildings. Some varieties can be shaped into detailed masonry.
Water absorption and durability can vary within a quarry. Weak bedding, unsuitable orientation or persistent saturation can contribute to deterioration.
Before you order: Ask how the stone should be oriented in the intended application, and review source-specific test information. Match finish, drainage and exposure requirements before approving outdoor paving.
Material reference: British Geological Survey: building-stone characteristics.
8. Travertine
Sedimentary carbonate stone
Travertine is a carbonate stone with characteristic pores and cavities. It can be supplied filled or unfilled and cut to show different patterns. The amount and treatment of those voids affect appearance, cleaning and suitability, so “travertine” alone is not a complete specification.
Typical uses: Interior floors and walls, bathroom surfaces and selected terraces or pool surrounds where the product meets the project requirements.
Warm tones and distinctive texture can create a relaxed interior or landscape palette. Vein-cut and cross-cut options offer different visual effects.
It is acid-sensitive. Filling materials, surface texture and finish influence maintenance and performance. A textured appearance is not proof of wet slip resistance or frost resistance.
Before you order: Specify filled or unfilled, cut direction, finish and filler requirements. For outdoor areas, request evidence for the exact product and exposure rather than copying an indoor specification.
9. Slate
Metamorphic stone
Slate is a fine-grained metamorphic rock that can split along closely spaced planes. This characteristic makes suitable varieties useful for roofing and textured finishes. Roofing slate, floor tiles and wall products are different specifications, even when the material name is the same.
Typical uses: Roofing, floor tiles, selected outdoor paving, wall cladding and landscape details.
A layered surface and typically restrained colours can create durable, textured finishes when the right product is selected.
Some products can flake, vary substantially in thickness or contain minerals that change appearance with exposure. Slate is not universally non-absorbent or immune to chipping.
Before you order: For roofing, request the relevant roofing-slate classification and fixing specification. For floors, check thickness tolerance, surface comfort, cleaning and wet slip performance.
10. Onyx
Decorative carbonate stone in the stone trade
Architectural stone sold as onyx is commonly banded calcite, a different material from the quartz variety also called onyx. Its translucency and dramatic banding make it a decorative choice. Use it where its appearance is valuable and where support, cleaning and protection can be carefully planned.
Typical uses: Backlit feature walls, reception fronts, decorative panels and carefully detailed furniture or vanity features.
Light transmission and vivid natural bands can produce a distinctive focal point. Slab sequence and lighting design can strongly influence the result.
Calcite onyx is relatively delicate and acid-sensitive. Large panels, edges and cutouts need careful handling; reinforcement and support depend on the actual slab and design.
Before you order: Approve the slabs both lit and unlit. Discuss backing, panel weight, fixing, lighting access and replacement access before fabrication.
Material reference: Natural Stone Institute: architectural onyx.
Buying guide: how to choose stone for your project
Start with the location and the job the stone must do. Then compare identified products using the same specification. A stone that works well in a sheltered wall feature may be the wrong choice for a wet entrance, exposed terrace or heavily used kitchen.
Match the stone to the application
| Application | Materials to investigate | Approval priorities |
|---|---|---|
| Interior floors and stairs | Granite, marble, limestone, travertine, slate or quartzite | Traffic, abrasion, wet slip conditions, joints, level changes, finish and maintenance. |
| Kitchen worktops | Granite or verified natural quartzite; marble where its care requirements are accepted | Actual slab, staining and etching expectations, cutouts, edges, support and cleaning. |
| Wet rooms and pool surrounds | Suitable products from several stone families; do not select by name alone | Wet slip performance, drainage, waterproofing, cleaning products and exposure. |
| Exterior paving and steps | Suitable granite, basalt, sandstone, slate or other proven exterior products | Local climate, saturation, frost or salt where relevant, loading, drainage and surface finish. |
| Facades and wall cladding | Specified granite, limestone, sandstone, marble or other suitable stone | Panel dimensions, flexural performance, anchors, support, movement joints and exposure. |
| Backlit or decorative interiors | Onyx and alabaster; selected translucent marble products | Lit sample, backing, support, impact protection, lighting heat and maintenance access. |
Which stones are used for walls?
Suitable limestone, sandstone, granite and other stones may be used as part of a designed masonry system. Unit quality, bedding, mortar, connections and local design requirements all matter.
The stone is a finish supported by another structure. Ask who designs the anchors or adhesive system, substrate, joints and weathering details.
Marble, travertine, onyx and other materials offer different visual effects. Panel size, backing, weight and edge protection remain important even indoors.
Distinguish the structural wall from its stone facing. Drainage, soil loads and foundations require project-specific design; a stone name is not a retaining-wall specification.
Stone properties: which tests should you request?
Avoid relying on a generic strength figure copied from a stone-family chart. A useful report identifies the material and source, sample condition, test method and results. Ask your project team which tests and acceptance criteria apply to the actual use.
| Property or detail | Why it matters | Example evidence to discuss |
|---|---|---|
| Absorption and density | Moisture behaviour and the weight of stone pieces | Source-specific results, such as ASTM C97 where specified. |
| Compressive strength | Relevant to specified bearing and masonry applications | Testing such as ASTM C170; this alone does not establish whole-building performance. |
| Flexural performance | Important for panels and supported pieces exposed to bending | Testing such as ASTM C880, with the relevant sample condition and orientation. |
| Cladding anchors and support | The connection must suit the stone and panel design | Anchor testing such as ASTM C1354 where relevant, plus the fixing design. |
| Slip, wear and exposure | The finished product must suit foot traffic and the environment | Project-appropriate slip and abrasion testing; frost or salt exposure evidence where required. |

Check the slabs, finish and fabrication before shipment
- Identify the product. Record the commercial name, material type, source or batch, finish, thickness and any resin, mesh or filling.
- Approve representative material. Use samples for colour and finish, then review actual slabs or batch photographs. Agree on acceptable variation, vein direction and the layout.
- Resolve fabrication details. Confirm dimensions, cutouts, edges, joints and tolerances against the latest drawings. The installer should verify site dimensions and support requirements.
- Agree on inspection records. Define measurement checks, surface inspection, dry-layout approval where needed and piece numbering. Match labels to the packing list.
- Plan delivery and after-sales. Confirm crate protection, unloading arrangements, receipt inspection and the written claim procedure before dispatch.

What affects the price of building stone?
Price depends on the exact stone and selection, available slab sizes, thickness, finish, usable yield, cutting complexity and order quantity. Backlighting details, bookmatching, curved pieces and complex edges add work. Freight, destination charges and installation also change the final project cost.

Frequently asked questions about building stones
What are the main types of stone used in construction?
This guide covers granite, marble, quartzite, alabaster, basalt, limestone, sandstone, travertine, slate and architectural onyx. They cover masonry, paving, cladding and decorative finishes; they are not interchangeable structural materials. Other stones, including gneiss, are also used where their properties and the application are suitable.
What is the best stone for building a house?
There is no single best stone for every part of a house. Select separately for walls, floors, stairs, worktops and outdoor areas. Compare the actual product, exposure, finish, installation and maintenance requirements rather than choosing solely by appearance or a generic stone name.
Which stone is strongest?
Strength depends on the particular material, test method, sample condition and direction of loading. A compressive-strength number does not answer questions about bending, anchors, slip resistance or weathering. Ask for the tests relevant to the intended use and have the project team set the acceptance criteria.
What is the difference between quartzite and quartz?
Natural quartzite is a metamorphic rock formed from quartz-rich sandstone. Engineered quartz is a manufactured surface using mineral particles and a binder. Their fabrication, care and exposure requirements differ. Confirm the actual material rather than relying on a similar-looking pattern or a trade name.
Can marble be used outdoors?
Some marble products are used outdoors, but suitability depends on the stone, finish, climate, installation and tolerance for weathering. Require evidence for the proposed application. An interior-polished marble specification should not automatically be reused for an exposed facade or wet terrace.
Does every natural stone need sealing?
No. The need depends on the stone, finish, application and supplier guidance. A suitable impregnating sealer can improve stain resistance but does not make stone stain-proof or prevent acid etching of carbonate materials. Use the recommended cleaning and maintenance instructions.
Which stone is best for wet floors or pool surrounds?
Choose a finished product with appropriate wet slip performance and suitability for the exposure, rather than assuming a stone type is safe. Drainage, slope, installation, cleaning and any pool chemicals also matter. Ask for evidence for the exact finish you intend to buy.
Can I order stone from a small sample?
Use a small sample to discuss colour and finish, but approve a representative batch or actual slabs for the order. Natural variation can be substantial. For vein matching or bookmatching, approve slab sequence, cut positions and seams before fabrication.
Can George coordinate stone with other building materials?
George provides project material sourcing. Send the stone schedule with your other material requirements so the team can discuss available options, fabrication and delivery scope. Confirm the actual stone, technical documents, installation responsibilities and commercial terms in the written proposal.
Care reference: Natural Stone Institute: care, cleaning and sealing. Use the instructions for your specific stone and finish.
Before you leave: turn your shortlist into a stone specification
Choose a small number of suitable materials, then compare samples, technical information and a complete quotation. A clear specification protects the design intent and makes conversations with suppliers, fabricators and installers more productive.
Planning stone for a villa, hotel or commercial project?
Send your drawings, applications, quantities, preferred finish, delivery location and target schedule. George can help you discuss material options and prepare an itemized project proposal.
