Bluestone Signature Grey Marble Slab 48656 is a full-scale natural marble surface for interiors where a darker neutral palette and quieter stone movement are preferred to highly expressive veining. Measuring 160 × 298cm, with a 20mm thickness and approximately 4.76m² surface area, the slab has a polished finish that gives greater definition to its smoky slate-grey colouring and subtle cloud-like mineral transitions.

The result is a grey marble with enough natural variation to provide material depth, but without the strong directional pattern found in more dramatically veined slabs. This makes Bluestone Signature Grey particularly adaptable across kitchens, bathrooms and wider interior schemes.

What does Bluestone Signature Grey Marble help you achieve?

Its main benefit is the ability to introduce a substantial natural-stone surface without making strong veining the dominant feature of the room.

The relatively controlled movement means the marble can work across larger areas while still allowing cabinetry, furniture, brassware or surrounding architecture to remain important.

Bluestone Signature Grey can help you:

• create a composed grey marble kitchen worktop or island
• fabricate a darker vanity top without moving to black stone
• extend the same material into a splashback
• introduce natural depth to a fireplace or feature panel
• create bespoke table tops and furniture surfaces
• build a coordinated blue-grey material palette across different formats

Because this is a full slab rather than a repeating manufactured surface, the finished piece still retains individual natural variation.

Where does this marble slab work best?

Starel positions slab 48656 for bespoke vanity tops, worktops, splashbacks and other fabricated interior pieces. Its wider marble-slab range is also intended for kitchen islands, bath surrounds, fireplaces, feature walls and bespoke stone furniture.

Kitchen worktops and islands are particularly relevant where a calm grey surface is wanted across a broad horizontal area. The 298cm slab length provides useful scope for larger components, subject to the final measurements and fabrication plan.

In bathrooms, Bluestone Signature Grey can work as a vanity top against lighter ceramics or as part of a more tonal scheme using Bluestone tiles. Used vertically, it can provide a restrained backdrop around a fireplace or feature wall without the highly graphic effect of strongly veined marble.

Final suitability depends on measurements, joints, cut-outs, edge profiles, support, access and the requirements of the individual project.

Why choose this exact Bluestone slab?

The key distinction is the balance between depth of colour and restrained natural movement.

Starel describes Bluestone Signature Grey through a deep smoky slate-grey field with fine grain and softer, cloud-like transitions rather than pronounced veins. This gives it a different role from statement marbles where contrasting veins become the principal feature.

The polished finish increases the visual definition of the grey and blue tones while providing a stronger finish contrast against honed Bluestone products elsewhere in the room.

This exact slab should still be selected and planned at full scale. Natural marble varies, and a small sample cannot communicate the complete distribution of tone and movement across a 160 × 298cm surface. Starel therefore states that cut samples are unavailable for its slab material.

Which Starel Stones products complement it?

The strongest pairing is the Bluestone Marble Tile Collection. Starel offers Bluestone in several honed and tumbled formats for interior walls and floors, including bathroom and kitchen applications.

This creates a useful finish relationship: the polished slab can provide greater surface definition across a vanity or worktop, while honed tiles create a softer backdrop across larger floor or wall areas.

For decorative detail, the Bluestone Geo Marble Mosaic uses a honed 305 × 305mm format and introduces smaller-scale geometric pattern.

The Bluestone Marble Penny Round Mosaic provides another option where softer circular geometry is preferred, particularly around selected bathroom or feature areas.

For architectural finishing, Bluestone Marble Honed Skirting can continue the stone family at floor level, while the wider Bluestone collection also includes pencil trims, dado mouldings and numerous additional mosaic formats.

These products coordinate through the broader Bluestone family, but exact tone and markings should not be expected to match perfectly because natural stone varies.

Slab selection, fabrication and care

Fabrication should be planned around the actual selected slab. Starel’s bespoke quote process allows drawings, dimensions and project requirements to be reviewed before the stone is cut.

Vein and tonal placement, cut-outs, joints and edge details should all be considered during this stage.

As natural marble, Bluestone Signature Grey should be sealed as appropriate for its final application and maintained with pH-neutral, stone-safe products rather than acidic or abrasive cleaners.

Bluestone Signature Grey Marble Slab 48656 is ultimately suited to projects that need natural marble with a quieter visual language: a substantial polished blue-grey surface that can anchor worktops, islands, vanity areas and bespoke interiors while connecting directly with Starel’s extensive wider Bluestone collection.

Trade pricing available for large quantity orders such as full bundles, complete batches or quantities exceeding half a container.

Note: Cut samples for this product are unavailable.

What are marble slabs best used for?

Marble slabs are best suited to projects where natural movement, veining and material character are central to the design. They are commonly used for kitchen islands, bathroom vanity tops, splashbacks, fireplace surrounds, feature walls, table tops and bespoke stone furniture. Compared with standard tiles, a marble slab gives a more continuous, architectural finish because larger sections of stone can be cut from one piece. Each slab is unique, so customers should select the exact slab where possible, especially when veining, bookmatching or colour tone is important. Marble is widely used for countertops, floors, walls, hearths and windowsills.

How do I choose the right marble slab for my project?

Start with the use of the stone, then choose the look. For a kitchen island or vanity top, your fabricator will need to understand the slab size, thickness, cut-outs, edge detail and any joins. For a feature wall, splashback or furniture piece, the movement and direction of the veining may matter more than surface wear. White Calacatta-style slabs create a brighter, refined look; darker marbles such as Nero or Picasso-style slabs create a stronger statement; beige, pink and warm-toned marbles soften a room. We recommend viewing marble slabs in person where possible, as photographs cannot fully show depth, surface finish or natural variation.

Can marble slabs be used for kitchen worktops and islands?

Yes, marble slabs can be used for kitchen worktops and islands, but they should be chosen with a clear understanding of how marble behaves. Marble is a natural calcareous stone, so it can mark, etch or stain if it is not sealed, cleaned and maintained correctly. For design-led kitchens, many customers choose marble because of its veining and timeless appearance, accepting that it will develop character over time. For high-use kitchens where low maintenance is the priority, quartz may be a more practical alternative. Marble surfaces should be sealed where appropriate and cleaned with suitable stone-safe products.

Do marble slabs need sealing?

In most interior applications, marble slabs should be sealed with a suitable natural stone sealer after fabrication and installation. Sealing helps improve resistance to everyday spills, oils and dirt, but it does not make marble stain-proof. The correct sealer depends on the stone, finish, location and use. Polished marble, honed marble and textured marble may absorb and wear differently, so your fabricator or installer should confirm the right sealing process. For kitchens, bathrooms and vanity areas, customers should also use coasters, trays and pH-neutral cleaners to protect the stone in daily use.

Can Starel deliver marble slabs to my fabricator?

Yes, marble slabs can usually be delivered to your chosen fabricator, installer or project site, provided the receiving address is suitable for heavy stone delivery. This is common for customers who select a slab from Starel and then ask their own fabricator to cut, finish and install it. Before dispatch, provide the fabricator’s full address, contact name, phone number, delivery access notes and unloading requirements. Marble slabs are heavy and fragile, so the receiving team must be prepared with the right handling equipment. For best results, confirm slab dimensions, bundle number and project requirements with your fabricator before ordering.

Are cut samples available for marble slabs?

For many slab listings, cut samples are not available. This is because slabs are sold as individual pieces or bundles, and cutting into a slab can reduce its usable area, commercial value and suitability for fabrication. Instead, customers should view the slab in person where possible, request additional photos or videos, or ask the team to show the slab in natural and showroom lighting. With marble, this is especially important because veining, tone, mineral markings and surface movement can vary significantly across a single slab. A tile sample from the same stone family should only be treated as a guide, not an exact match.

Is marble suitable for trade and larger project orders?

Yes, marble slabs are highly suitable for trade, design and development projects where multiple surfaces, matched pieces or full-bundle supply may be required. The product export repeatedly notes trade pricing for larger quantity orders, including full bundles, complete batches and quantities exceeding half a container. This is useful for interior designers, architects, developers, fabricators and contractors who need batch consistency and project planning support. For larger orders, speak to Starel early so the team can confirm slab availability, bundle numbers, lead times, delivery options and whether the selected material can be held, reserved or supplied as part of a wider stone package.

What are quartz slabs best used for?

Quartz slabs are best used for high-use surfaces where durability, consistency and lower maintenance are important. In the Starel slab export, quartz is listed as Cimstone quartz, with polished finishes and 2cm / 3cm options. Quartz is particularly suited to kitchen worktops, islands, utility rooms, bathroom vanity tops, commercial counters, hospitality surfaces and other practical interiors where customers want a refined stone look with more predictable performance. Cimstone describes its quartz surfaces as hard-wearing, non-porous, stain-resistant and easy to clean, making them a strong option for busy residential and commercial projects.

How is quartz different from marble?

Quartz is an engineered surface, while marble is a natural stone. Marble is selected for natural veining, unique slab movement and classic material depth. Quartz is selected for consistency, lower porosity and easier day-to-day maintenance. If a client wants dramatic natural variation and accepts the care requirements, marble is often the preferred choice. If the project needs a practical kitchen worktop, a cleaner finish, colour consistency or stronger resistance to everyday staining, quartz is often more suitable. Cimstone quartz contains natural quartz, one of the harder minerals used in engineered surfaces, and is designed for long-term surface performance.

Do quartz slabs need sealing?

No, quartz slabs generally do not need sealing because they are engineered to be non-porous. This is one of the main reasons customers choose quartz for kitchen worktops, islands and bathroom surfaces. Unlike many natural stones, quartz does not usually require periodic sealing to resist everyday spills. Routine cleaning is normally simple: a soft cloth, warm water and mild detergent are usually enough. Harsh abrasives, steel wool and aggressive cleaners should still be avoided, as they can dull or damage the surface finish over time.

Are quartz slabs good for kitchen worktops?

Yes, quartz slabs are one of the most practical choices for kitchen worktops and islands. They offer a strong balance of design, durability and ease of care. In Starel’s catalogue, the Cimstone quartz slab range includes marble-look designs such as Calacatta styles, as well as neutral, dark and architectural finishes. This makes quartz useful when a customer wants the visual language of marble but with a more consistent and lower-maintenance surface. Quartz is also well suited to busy kitchens because of its low porosity and resistance to staining from everyday food and drink spills.

Can quartz slabs be fabricated by my own worktop specialist?

Yes, quartz slabs can be supplied to a customer’s chosen fabricator or worktop specialist, provided the order, delivery and handling details are confirmed in advance. The fabricator should confirm the slab thickness, measurements, cut-outs, edge profiles, joins, sink type, hob type and installation requirements before the slab is ordered. Quartz fabrication should only be carried out by competent professionals with the correct equipment and safety controls. Cutting or processing engineered stone can create hazardous respirable crystalline silica dust, and HSE guidance requires proper controls when working with natural, artificial or engineered stone.

Should I choose 2cm or 3cm quartz slabs?

The right quartz thickness depends on the design, support structure, edge detail and fabricator’s recommendation. In the Starel export, Cimstone quartz slabs are structured with 2cm and 3cm variation options. A 2cm slab may be used where a slimmer profile is desired or where the fabricator plans to build up the edge detail. A 3cm slab gives a thicker, more substantial appearance and may be preferred for some worktops, islands and commercial counters. Your fabricator should confirm the best thickness based on span, substrate, support, cut-outs and final installation method.

Is quartz suitable for trade, commercial and hospitality projects?

Yes, quartz is well suited to trade, commercial and hospitality projects because it offers predictable colour options, practical maintenance and strong performance for high-use interiors. Designers, contractors and developers often choose quartz for kitchen worktops, apartment schemes, bar counters, vanity tops, reception counters and rental properties where the surface needs to look refined but remain practical. The Starel quartz range is built around Cimstone slabs, giving customers a clear material family with multiple colourways and thickness options. For larger projects, trade customers should confirm availability, slab sizes, batch consistency, delivery timing and whether full-bundle or project pricing is available.

What are travertine slabs best used for?

Travertine slabs are best used where the project calls for warmth, texture and a softer architectural feel. Starel’s travertine slab range includes Light Travertine and Pink Travertine, both positioned around natural tonal movement, pitted texture and a more organic finish than polished marble. Travertine works well for bathroom vanities, fireplace surrounds, wall cladding, table tops, bath surrounds, shelves and selected flooring or interior features. It is especially effective in Mediterranean, soft-modern, spa-inspired and natural interiors. The stone’s linear movement and earthy palette make it a strong choice when a room needs warmth rather than high-contrast veining.

Why does travertine have holes or pits?

Is travertine suitable for bathroom vanity tops and wet areas?

Travertine can be used for bathroom vanity tops, bath surrounds and selected wet-area features, but it needs correct sealing, installation and maintenance. Because travertine is a natural calcareous stone, it can react to acidic products and can absorb moisture if not properly protected. In bathrooms, the fabricator and installer should confirm sealing, edge detailing, drainage, substrate preparation and whether the finish is suitable for the level of water exposure. Travertine is often chosen for bathrooms because its warm tones and tactile surface create a softer, spa-like feel than many colder stones.

What is the difference between honed and polished travertine slabs?

A honed travertine slab has a smoother, more matte surface that feels natural, calm and understated. It is often chosen for bathrooms, floors, wall cladding and interiors where a softer finish is preferred. A polished travertine slab has more shine and reflects more light, which can make the stone feel richer and more formal. In the Starel export, the travertine slab group includes both honed and polished finishes. The right finish depends on the project style, required slip considerations, maintenance expectations and whether the surface is being used vertically, horizontally or as a working surface.

Can travertine slabs be used for kitchen worktops?

Travertine can be used in kitchens, but it is usually better suited to carefully considered, design-led applications rather than heavy-use, low-maintenance worktops. It is more porous and textured than quartz, and it needs proper sealing and careful daily use. For a kitchen island, breakfast bar or feature surface, travertine can be beautiful, especially where warmth and natural banding are important. For a busy family kitchen where stain resistance and ease of care are the priority, quartz may be more practical. Customers should always confirm suitability with a fabricator before choosing travertine for a kitchen surface.

Are cut samples available for travertine slabs?

For slab listings, cut samples are generally unavailable. This is particularly important with travertine because its movement, banding, voids, fill, tone and texture can vary significantly from one area of the slab to another. The best way to choose travertine is to view the specific slab, review detailed photos or ask for a video showing the full face and surface finish. For trade and fabrication projects, always reference the bundle number and confirm whether the selected slab has enough workable area for the intended pieces, cut-outs and edge details.

Can Starel supply travertine slabs for trade and bespoke fabrication?

Yes, travertine slabs can be supplied for trade, fabrication and bespoke interior projects, subject to stock, slab size and project requirements. Travertine is well suited to vanity tops, splashbacks, bath surrounds, fireplace surrounds, wall cladding, shelving and architectural details where the warmth of natural stone is part of the design brief. For larger orders, the Starel export notes trade pricing may be available for full bundles, complete batches or larger quantities. Designers, fabricators and contractors should confirm slab dimensions, finish, surface condition, delivery destination and installation environment before reserving or purchasing.

What are onyx slabs best used for?

Onyx slabs are best used for statement interiors where the stone is intended to be a focal point. Starel’s onyx slab range includes expressive materials such as Jurassic Green, Lavanda Violet, Velluto, Mint Green and Cashmere Onyx. These slabs are suited to backlit feature walls, powder room vanities, bar fronts, splashbacks, decorative panels, furniture details and luxury bathroom features. Onyx is chosen less for everyday practicality and more for depth, translucency, colour and visual drama. It should be specified carefully, especially where lighting, support, handling and fabrication need to be planned before installation.

Can onyx slabs be backlit?

Yes, many onyx slabs can be backlit because onyx is known for its translucent quality. When the lighting is planned correctly, the slab can glow from within and reveal veining, colour layers and mineral movement that are not visible in ordinary light. Backlighting should be designed early with the fabricator, lighting designer and installer because thickness, backing, LED placement, diffusion, access and fixing method all affect the final result. Not every onyx slab transmits light in the same way, so the exact slab should be tested before fabrication where backlighting is critical.

Is onyx suitable for kitchen worktops?

Onyx can be used in kitchens, but it is usually better suited to decorative or lower-impact areas than everyday working surfaces. It is softer and more delicate than many other slab materials, and it needs careful sealing, handling and maintenance. For a kitchen, onyx may be better used as a feature splashback, bar front, display island panel or decorative surface rather than the main preparation worktop. If the customer wants a practical, lower-maintenance kitchen worktop, quartz is normally the safer recommendation. If the customer wants a showpiece, onyx can be exceptional when specified correctly.

How do I choose the right onyx slab?

Choose onyx by looking at the exact slab, not just the material name. Onyx varies heavily in colour, translucency, banding, opacity, veining and mineral movement. A slab such as Lavanda Violet may suit a soft, expressive bathroom, while Jurassic Green or Mint Green can create a much bolder feature. If the slab will be backlit, ask for the material to be reviewed with light behind it before final approval. For fabrication, the customer should confirm the visible face, orientation, joins, cut-outs and whether the design depends on a particular section of the slab.

Does onyx need sealing and special care?

Yes, onyx needs careful sealing and maintenance. It is a natural calcareous stone, so acidic products, abrasive cleaners and harsh chemicals should be avoided. Use pH-neutral stone cleaners, wipe spills quickly and protect the surface from cosmetics, perfumes, wine, citrus, oils and aggressive bathroom cleaners. Onyx is often selected for luxury bathrooms, powder rooms and decorative surfaces, but it should be treated as a premium feature material rather than a hard-wearing utility surface. The right care plan should be confirmed by the fabricator or installer based on finish, location and exposure.

Are cut samples available for onyx slabs?

For Starel’s slab listings, cut samples are generally unavailable. With onyx, this is understandable because each slab is highly individual and often selected for a specific face, colour pattern or translucent quality. A small cut sample may not represent the final slab accurately, especially if the stone has strong banding or dramatic variation. Customers should view the slab in person where possible, request full-slab photos, ask for video, and, for backlit projects, ask whether the slab can be shown with light behind it. This gives a more useful understanding than a small sample.

Can onyx slabs be delivered to my fabricator or installer?

UK slab delivery

Starel Stones can arrange UK slab delivery for marble, quartz, travertine and onyx slabs, including delivery to your home, project site, fabricator or installer of choice.

Slabs are specialist products. They are large, heavy and often selected for a specific face, vein movement, colour tone or fabrication requirement. For this reason, slab delivery is handled separately from standard tile and sample orders.

Before dispatch, our team will confirm the delivery address, site access, receiving contact and unloading requirements. Slabs may require specialist vehicles, A-frame transport or suitable unloading equipment depending on the material, slab size, quantity and destination. If your order is being delivered directly to a fabricator, installer or contractor, please provide their full delivery details before the order is released.

We strongly recommend that the receiving party is prepared for the delivery before the slab arrives. The site should have suitable access, enough space for safe unloading and an experienced person available to inspect and receive the material. Slabs should not be booked for fabrication or installation until they have been received, checked and approved.

For customers purchasing slabs for worktops, vanity tops, splashbacks, bath surrounds, feature walls or bespoke stonework, delivery can be coordinated around your project timeline where possible. Lead times may vary depending on stock availability, fabrication requirements, delivery location and the number of slabs being supplied.

If you are unsure whether your property, site or fabricator can receive slab delivery, speak to our team before placing your order.

International slab delivery

Starel Stones can support international slab delivery for selected slab orders, subject to destination, order size, product availability and transport requirements.

International slab orders require careful planning. Natural stone slabs must be packed, handled and transported correctly to protect the material during long-distance freight. Depending on the destination and project scope, slabs may be supplied to private clients, interior designers, developers, contractors, fabricators or commercial project teams.

Before confirming an international slab order, our team will review the material, slab dimensions, quantity, destination country, delivery address, freight requirements and receiving arrangements. Where the slabs are being sent to a local fabricator or installation partner, we will need their full business details, contact information and unloading requirements.

International customers should allow for additional lead time, freight coordination, customs clearance and any duties, taxes or local charges that may apply in the destination country. These costs and responsibilities should be confirmed before the order is finalised.

For larger international projects, full-bundle or multi-slab supply may be available. This can be especially useful for designers, developers and trade professionals who need consistency across bathrooms, kitchens, hospitality spaces, feature walls or wider stone packages.

Fabrication

Starel Stones offers in-house fabrication options for customers who want a more complete stone service beyond slab supply. Our fabrication service is designed for projects that require precision cutting, finishing and made-to-measure stonework. This can include vanity tops, splashbacks, kitchen worktops, island tops, bath surrounds, shower walls, feature panels, table tops, shelves, niches, steps, risers and other bespoke stone details.

Working with our fabrication team allows you to move from material selection to finished stone element with greater clarity. Once the slab or material has been selected, we can review the intended use, dimensions, drawings, cut-outs, edge details, finish, access requirements and delivery destination. From there, we can prepare a quotation based on the material, fabrication complexity and project scope.

Fabrication is especially valuable when the stone needs to work across several parts of a room. A marble vanity top can be paired with a matching splashback. A slab selected for a kitchen island can be planned around vein direction, visible faces and edge treatment. A bathroom scheme can be developed with coordinated stone surfaces, from wall panels and bath surrounds to shelves and niche details. Each material is assessed according to its use. Marble offers natural veining and timeless movement, but requires careful sealing and maintenance. Quartz is a practical choice for high-use worktops and commercial surfaces. Travertine brings warmth, texture and architectural softness. Onyx is best treated as a feature material, often used for decorative panels, powder rooms, bars and backlit stone applications.

All fabrication work is quote-based. Final pricing depends on the selected slab, required cuts, measurements, edge profiles, cut-outs, polishing, finishing, handling and delivery. Production should only begin once the specification has been confirmed, the quote has been approved and any required payment terms have been met.

For accurate pricing, please provide drawings, measurements, site photographs, product references and any design requirements when submitting your enquiry. Where needed, our team can advise on the most suitable material, finish and fabrication route for your project.

If you already have a fabricator, Starel can supply slabs directly to them. If you would like Starel to handle fabrication, our team can guide you through the next steps and prepare a tailored quote.
