Königstone Explains “Stone Surfaces”

When specifying stone surfaces for kitchen projects, clarity around terminology and material characteristics is essential. Joanne Bull, Marketing Manager at Königstone, offers a practical breakdown of the main surface categories and what designers need to consider when working with them.

 Quartz/Engineered Stone surfaces

Often referred to interchangeably, quartz and engineered stone surfaces are man-made materials composed of natural minerals bound with resin. This resin content enhances flexibility which enables highly intricate edge profiles and long spans with large cut-outs.

These surfaces are virtually non-porous, delivering high stain resistance and a smooth, hygienic finish that’s easy to clean and maintain. While traditionally composed of over 90% natural quartz, newer formulations are evolving to include alternative minerals and recycled glass, reducing or eliminating silica content. As a result, the term ‘Quartz worktops’ is gradually being replaced by ‘Engineered stone surfaces’ across the industry.

Porcelain/Ceramic/Sintered Stone surfaces

These surfaces are manufactured by compacting raw materials under high pressure and firing them at extreme temperatures. Though marketed under different names, porcelain, ceramic, and sintered stone share similar production methods and properties.

Key benefits include:

• High heat resistance – hot pans can be placed directly on the surface.

• Scratch resistance – metal knives can be used without damaging the surface.

However, their hardness can make them slightly more brittle than engineered stone, and they often require additional joints in long runs or around large cut-outs. Most slabs are not full-bodied, meaning the design is printed on the surface. This affects edge detailing, making simple profiles like double bevels, shark’s nose, or mitred edges more suitable.

Their thin, lightweight nature also makes them ideal for wall cladding and feature furniture, such as stone-faced doors and drawer fronts.

Exotic Natural Stone

Exotic natural stones are prized for their dramatic colours, veining, and unique mineral inclusions. Each slab is one-of-a-kind, offering a bespoke aesthetic that’s difficult to replicate. Königstone’s KönigNaturals collection features three main types:

Exotic Granites

Formed from the slow crystallisation of magma, granites are rich in quartz, feldspar, and mica. Their striking veining is the result of natural inclusions and impurities.

Exotic Quartzites

Composed almost entirely of quartz, quartzites offer a hard, glassy appearance. While generally harder than granite, exotic varieties may contain mineral inclusions that create weak points. The perfect example is the Patagonia finish.

Exotic Dolomites

Dolomites are denser than limestone and often display soft pink or brown hues. Their hardness sits between granite and marble, but they are more prone to scratching and acid etching – making polished finishes less suitable.

Design considerations

Natural stone is inherently porous. KönigNaturals enhances protection with a ‘once only’ anti-stain treatment, but prompt cleaning remains essential – especially around mineral junctions. Narrow rails and corner cut-outs can be fragile, and while moulded edge profiles are possible, they may require repairs during production. Even the toughest stones can chip if mishandled, particularly around mineral inclusions.

At Königstone, we are committed to delivering high-quality surfaces with a focus on environmental responsibility. Our surfaces are designed for longevity, reducing the need for replacement and minimising waste. Many of our products including the KönigCeramic and Athena Collection ranges incorporate recycled materials and are virtually non-porous, requiring no harsh chemicals for cleaning, supporting healthier homes and a lower environmental footprint. We work with manufacturing partners who implement energy-efficient processes and water recycling systems. As part of our ongoing commitment to sustainability, we continue to explore innovative materials and practices, including low and zero silica Quartz options that enhance safety for fabricators and reduce environmental impact.
