Comparing Natural Granite, Marble, Quartzite & Slate

Natural stone worktops and surfaces are highly sought after for many applications throughout the home and public spaces.

Natural stone has strong weather resistance which allows them to be used both internally and externally. It is a versatile choice for many projects and available in a wide range of colours and patterns that cannot yet be matched by engineered stone.

Viewing Natural Stone Materials

Viewing natural stone slabs are strongly advised due to variations in veins and patterning. With natural materials, the colouration and veining can be substantially different from each end of the slab, this can occasionally be true also for engineered materials, especially those with veins.

Orientation of the slab, direction of veins, and pattern positioning is all very important, as in many cases, the slab can be cut in at least 2 different orientations. Naturally, we match veins as closely as possible during fabrication whilst maximising materials to keep costs within a budget. If you have the time, our stone worktop fabricators would be happy to see you at time of cutting to ensure you get the cuts just the way you want them.

Granite Worktops & Colours

As one of the toughest natural stone worktop surfaces, granite is highly resistant and durable, suitable for flooring and external use.

Natural Stone

Marble Worktops & Colours

Adds luxury to any home project, its wide diversity of colour, patterning, and veining makes it perfect for worktops, flooring and cladding.

Natural Stone

Quartzite Worktops & Colours

A very hard natural stone with strikng veins and colours great for indoor and outdoor applications.

Natural Stone

Slate Surfaces

Durable, heat-resistant, timeless, and naturally rustic slate is particularly well known for roofing, floor tiles, and coping.

Other Natural Stone Materials

We also fabricate a wider range of natural stone surface materials including: Onyx, Limestone, Sandstone and Travertine - Contact us if you require an estimate or would like to discuss stone options.

Natural Stone Resistances & Hardness

Resistances of a natural stone kitchen worktop are paramount when it comes to choosing a solid stone for your kitchen.

Pores & Fissures

Natural stone contains a network of pores and, in some materials, natural fissures that can allow fluids to penetrate the surface. Heavily veined stones such as quartzite may contain natural fissures where dirt and moisture can collect.

Liquids can carry staining substances into these areas, potentially affecting the appearance of the stone. Appropriate sealing reduces fluid absorption and helps protect the surface from staining and everyday moisture.

The level of porosity and sealing required varies between stone types, so maintenance should be matched to the specific material and its application.

Natural Stone Comparison

Quartz mineral content directly relates to a natural work surface scratch resistance

Scratch resistant

  • Marble: 30% Average Quartz Content - 4/10 hardness
  • Slate: 30% Average Quartz Content . 5/10 hardness

Highly scratch resistant

  • Granite: 40% Average Quartz Content - 7/10 hardness
  • Quartzite: 85% Average Quartz Content - 8/10 hardness

Fissures in this quartzite worktop in place of veins provide good reason to seal worktops to prevent ingress of dirt and grime.

Environmental Conditions

Natural stone forms over long periods under extreme heat and pressure deep within the Earth.

Geological processes such as tectonic plate movement, volcanic activity, and ocean floor sedimentation determine how different rock types form. Over unthinkably long times, weathering and erosion recycle existing rock material in a process known as the rock cycle.

Quartz Mineral Content & Colour

The colour and pattern of natural stone are determined by the minerals present during its formation and the environmental conditions at that time. These minerals create a wide range of unique combinations and patterns, ranging from plain tones to highly veined designs, from white to black.

How material clarity and colour affects costs

Several factors influence the cost of slabs used for fabricating natural stone worktops and natural surfaces. A clean white marble slab with evenly spaced, desirable veins is usually graded as high-end material, making it more expensive than an uneven grey background or complex veining. Material type, slab size, and thickness also affect cost — for example, large granite and quartzite slabs tend to be more expensive than smaller ones or slate slabs.
