The Stone

See the natural beauty of Black Slate Honed up close — the surface texture, colour depth, and veining that make this marble unique.

A dark charcoal natural slate with industrial-chic character and a practical honed matte finish

Black Slate Honed is a dark, brooding natural stone that brings an industrial-chic character to kitchen design. Commercially traded alongside marbles, this is actually a slate — a fine-grained metamorphic rock formed from compressed clay sediments — which gives it a distinctly different texture and personality from true marble. Its uniform dark charcoal base is punctuated by scattered fine white crystalline veins, while the honed matte finish provides a contemporary, non-reflective surface. The non-glossy surface is both visually striking and practically beneficial — fingerprints, water marks, and minor wear are far less visible on a honed slate surface than on polished marble. This makes Black Slate Honed an excellent choice for homeowners who want a dramatic dark worktop without the high-maintenance requirements of a polished finish. The stone's masculine, architectural character pairs beautifully with concrete-effect walls, timber cabinetry, and brushed metal fixtures.

Frequently Asked

Questions About Black Slate Honed

Is Black Slate Honed actually slate or marble?
Black Slate Honed is actually a genuine slate — a fine-grained metamorphic rock formed from compressed clay sediments. It is commercially categorised alongside marbles for the worktop market, but its geological properties and character are distinctly different from true marble.
What are the advantages of slate over marble for worktops?
Slate offers some practical advantages: its naturally non-porous structure requires less frequent sealing than marble, it is less susceptible to acid etching, and its honed matte surface conceals fingerprints and watermarks well. However, it can be slightly more brittle and should be handled with care during installation.
What does the honed finish mean on Black Slate?
Honed means the surface has been ground smooth but not polished to a high gloss. This creates a matte, non-reflective surface with a tactile, natural quality. For a dark stone like Black Slate, the honed finish provides a contemporary, industrial-chic character that is both striking and practical.
How should I care for a Black Slate Honed worktop?
Clean regularly with pH-neutral stone cleaner and a soft cloth. Seal every 6-12 months with a quality penetrating sealant. Although slate is more resistant to acids than marble, we still recommend wiping spills promptly. The matte surface is low-maintenance and hides everyday wear well.
Does Black Slate Honed come in other finishes?
Yes, this stone is available in three distinct finishes: Honed (matte), Satinato (satin-brushed), and Riven (natural cleft). Each finish transforms the character of the stone dramatically. Visit our showroom to compare samples and find the finish that best suits your kitchen design.
