Choosing a stone worktop is one of the most significant decisions you'll make in a kitchen or bathroom renovation. Get it right and it defines the space for decades. Get it wrong and you'll be reminded of it every morning over a cup of tea.
The challenge is that ‘stone’ covers a huge amount of ground. Granite, marble, quartz, quartzite, porcelain, slate, onyx, semi-precious - each one has its own character, its own demands and its own reasons to love it. What works brilliantly in a busy family kitchen may be entirely wrong for a statement bathroom, and vice versa.
This guide covers every type of stone worktop The Stone Family supplies, explaining what each material actually is, what makes it distinctive and where it performs best. If you’re just starting your research, this is the place to begin.
Granite
What is granite stone?
Granite is an igneous rock, formed deep within the earth’s crust as molten magma cools and solidifies over millions of years. The slow cooling process produces large mineral crystals - primarily quartz, feldspar and mica - which give granite its characteristic speckled appearance and grainy texture.
Because it forms naturally, no two slabs are ever identical. The colour, pattern and mineral composition will vary depending on where in the world the stone was quarried. This is part of what makes granite worktops so appealing: you’re bringing something genuinely unique into your home.
What are the key properties of granite?
Extremely hard and scratch-resistant
Heat-resistant - one of the most tolerant natural stones for kitchen use
Naturally porous, so periodic sealing is recommended
Available in a vast range of colours and patterns, from classic black and grey to deep blues, greens and golds
Each slab is unique
Where does granite work best?
Granite is one of the most practical natural stone options for kitchens. Its hardness means it handles daily use without flinching, and its heat resistance makes it well-suited to worktops near hobs and ovens. It also works well in bathrooms, utility rooms, and commercial settings.

Marble
What is marble stone?
Marble is a metamorphic rock formed when limestone is subjected to intense heat and pressure deep within the earth. Over time, the calcite crystals in the limestone recrystallise, producing a denser, finer-grained stone with the iconic veining marble is known for.
That veining is the result of mineral impurities - traces of clay, silt, sand and iron oxides - worked through the stone during its formation. No two marble slabs share the same vein pattern, which is why marble interiors feel so considered and personal.
What is the difference between marble and granite?
Granite is igneous (formed from cooled magma); marble is metamorphic (formed from transformed limestone). In practical terms, this means marble is softer than granite, more susceptible to etching from acidic substances and requires more careful maintenance. However, marble’s depth and aesthetic is great for many applications.
What are the key properties of marble?
Softer than granite - more vulnerable to scratching and etching
Can be affected by acidic foods and drinks (lemon juice, wine, vinegar)
Requires regular sealing and careful maintenance in kitchen environments
Available in white, grey, cream, green, pink and dramatic dark tones
Timeless aesthetic with unmatched visual depth and movement
Where does marble work best?
Marble works well in bathrooms, where it faces less daily use than in a kitchen. In kitchens, it suits those who appreciate a living surface - one that develops character over time - and are willing to maintain it accordingly. It’s also a natural choice for pastry and baking areas, as the cool surface is ideal for working with dough.

Quartz
What is quartz stone?
Quartz worktops are engineered surfaces, not purely natural stone. They’re made by combining around 90-95% crushed natural quartz crystals with resins, polymers and pigments under heat and pressure. The result is a highly consistent, non-porous surface that takes its aesthetic cues from natural stone while offering significant practical advantages.
What is the difference between granite and quartz?
Granite is 100% natural stone; quartz is an engineered product made with natural minerals. Granite has natural variation in every slab; quartz is manufactured to be consistent. Granite requires periodic sealing; quartz is non-porous and requires no sealing. Both are extremely durable, but quartz generally offers more predictability, while granite offers more uniqueness.
What are the key properties of quartz?
Non-porous - highly resistant to staining and bacteria
No sealing required
Consistent appearance across slabs which is useful for large or multi-slab installations
Extremely wide range of colours and finishes, including options that mimic marble and natural stone
Can be sensitive to very high heat - trivets are recommended near hobs
Not suitable for outdoor use
Where does quartz work best?
Quartz is an excellent choice for busy kitchens where low maintenance is a priority. Its non-porous surface makes it resistant to staining from cooking oils, wine and acidic foods, and it cleans easily. It’s also a popular choice for bathrooms and utility rooms.
We supply quartz from leading brands including Caesarstone, Silestone, Cimstone and CRL.
Quartzite
What is quartzite?
Quartzite is a naturally occurring metamorphic rock formed when sandstone rich in quartz is subjected to extreme heat and pressure. Unlike engineered quartz, quartzite is 100% natural stone - quarried directly from the earth and fabricated into worktops without artificial enhancement.
What is the difference between quartz and quartzite?
Quartz is sometimes confused with quartzite, but they’re fundamentally different materials.
Quartz is an engineered product; quartzite is a natural stone. Quartzite is typically harder than quartz and more heat-resistant, making it a strong choice for kitchens. However, because it’s a natural stone, it’s porous and will need sealing, whereas engineered quartz does not.
Quartzite also tends to have a more unique, natural appearance - often with subtle movement and veining - compared to the manufactured consistency of quartz.
What are the key properties of quartzite?
One of the hardest natural stones available for worktops
More heat-resistant than engineered quartz
Naturally porous - requires sealing
Unique veining and natural variation in every slab
Often resembles marble aesthetically, with greater practical durability
Where does quartzite work best?
Quartzite is an excellent option for those who want the beauty of natural stone with outstanding durability. It’s particularly well-suited to kitchen worktops and is increasingly popular as a premium alternative to both marble and quartz.
Porcelain
What is porcelain stone?
Porcelain worktops are made from refined clay minerals fired at very high temperatures - a process that produces a dense, hard and non-porous surface. Modern porcelain can be manufactured to replicate the look of natural stone, concrete, wood and more, often with a level of realism that makes it difficult to distinguish from the real thing.
Porcelain slabs for worktops are typically very thin - often 6mm to 12mm - and lightweight relative to natural stone, making them easier to handle and install in certain applications.
What are the key properties of porcelain?
Extremely hard and scratch-resistant
Non-porous - highly resistant to staining, bacteria and moisture
No sealing required
UV-resistant - suitable for outdoor kitchens and external use
Heat-resistant
Consistent appearance - patterns and colours are manufactured to specification
Available in very large format slabs for minimal visible joins
Where does porcelain work best?
Porcelain is one of the most versatile materials available. Its UV resistance makes it the standout choice for outdoor kitchens and al fresco entertaining spaces. Indoors, it works well in both kitchens and bathrooms, and its resistance to moisture makes it particularly suitable for wet rooms and shower enclosures.
We supply porcelain from Dekton, Neolith, Laminam, Lapitec and Ceralsio. Browse the full range on our Stone Finder.
Slate
What is slate stone?
Slate is a fine-grained metamorphic rock formed from shale or mudstone under low-grade heat and pressure. The result is a dense, layered stone with a distinctive cleft texture and a depth of colour that ranges from charcoal black and blue-grey through to rich greens and purples, depending on the quarry of origin.
Slate has been used in British architecture for centuries - most familiarly on rooftops - but it’s increasingly sought after as a worktop and cladding material for both interior and exterior applications, valued for its texture and character.
What are the key properties of slate?
Dense and durable - resistant to general wear and tear
Naturally textured surface that conceals minor marks and dirt well
Resistant to staining with appropriate treatment
Available in a range of finishes: honed, satin, riven, and polished
Naturally cool surface, similar to marble
More affordable than many premium natural stones
Suitable for internal and external applications
Where does slate work best?
Slate is a versatile choice that suits both traditional and contemporary interiors. Its dark tones and textured surface work particularly well in kitchens looking for a raw, natural aesthetic, and it’s equally at home in bathrooms, utility rooms and on external terraces. The naturally cool surface also makes it a practical choice for food preparation areas.
It’s worth noting that slate is softer than granite and quartzite, so care should be taken with heavy impact, and periodic sealing helps maintain its appearance over time.
Browse our slate range, including Black Slate Duro Satin and Black Honed finishes.
Onyx
What is onyx stone?
Onyx is a banded variety of chalcedony - a microcrystalline form of quartz - and one of the most visually dramatic stones available for interiors. Formed through the slow deposition of silica in gas cavities within lava, onyx develops its characteristic banding and translucency over geological timescales.
It has been used in architecture and decorative arts for thousands of years, and its combination of bold colour, strong banding and natural translucency makes it uniquely suited to statement interiors.
What are the key properties of onyx?
Striking banded appearance with strong colour and natural movement
Naturally translucent - highly effective when backlit
Available across a wide colour spectrum: amber, green, white, grey and black
Softer than granite and quartzite - more suited to lower-traffic surfaces
Porous - requires sealing and careful maintenance
Each slab is entirely unique
Where does onyx work best?
Onyx is best understood as a feature material. It performs beautifully on bathroom vanity tops, bar surfaces and feature islands - anywhere it will be seen and properly lit. Its translucency makes it one of the only worktop materials that genuinely transforms under backlighting, creating an effect that has to be seen in person to be fully appreciated.
Because onyx is relatively soft and porous, it’s less suited to heavy-duty kitchen use, but in the right setting it’s one of the most impressive materials available.

Semi-Precious Stone
What are semi-precious stone worktops?
Semi-precious stone worktops are made from gemstone-quality minerals including agate, amethyst, tiger’s eye, malachite and labradorite.
Like onyx, semi-precious stone slabs are often backlit to take full advantage of their natural translucency. The results are surfaces that appear to glow from within, and which function as genuine works of art as much as practical worktops.
Our Elite Range sits within this premium tier, featuring a curated selection of luxury stones, including Amazonite and Bardiglio, handpicked by our stonemasons for exceptional quality and visual impact.
What are the key properties of semi-precious stone?
One-of-a-kind aesthetics
Available in materials including agate, amethyst, malachite and tiger’s eye
Often translucent and highly suited to backlighting
Softer than granite and quartzite - best suited to feature and lower-traffic surfaces
Premium pricing reflective of rarity and visual impact
Where does semi-precious stone work best?
Semi-precious stone is chosen when the worktop is meant to be the centrepiece of the room. Feature islands, bathroom vanity tops and bar surfaces are all natural homes for these materials.

How to choose the right stone for your project
With so many excellent options, narrowing it down comes down to a few core questions:
How much maintenance are you willing to do?
Natural stones like granite, marble, quartzite, slate, onyx and semi-precious stone require periodic sealing. Engineered quartz and porcelain are non-porous and need no sealing at all. If low maintenance is a priority, quartz and porcelain are the most straightforward choices.
What kind of use will the surface see?
Busy family kitchens call for durable, forgiving materials. Granite, quartzite and quartz are all excellent here. Marble and slate suit lighter-use kitchens or bathroom applications. Onyx and semi-precious stone are best reserved for feature surfaces. Porcelain is the go-to for outdoor use.
What’s the aesthetic you’re after?
If you want natural variation and unique character, natural stone is the answer. If you want consistent colour and pattern across a large installation, engineered quartz or porcelain offers more predictability.
What’s the application?
Kitchen worktop, bathroom surface, outdoor kitchen, feature island - the usage matters. We’d always recommend discussing your project with our team to make sure you’re getting the right material for the right context.
