Onyx Slabs

Onyx slabs are some of the most dramatic and visually captivating natural stone surfaces available. Known for their vibrant patterns, rich colours and striking translucency, onyx slabs add a luxurious, artistic touch to interiors and premium projects across the UK.

Ideal for feature walls, backlit installations, countertops, statement tabletops and bespoke design features, onyx creates an unrivalled look that allows the stone’s natural beauty to shine, especially when backlit to accentuate its depth and glow.

Applications for Onyx Slabs

Onyx slabs are most often chosen for high end and bespoke design applications, including:

• Backlit walls and panels creating luminous feature surfaces
• Statement countertops & islands
• Feature tabletops & furniture inserts
• Luxury bathroom vanities & wall cladding
• Decorative architectural elements

Due to its dramatic appearance and softer nature compared with some other stones, onyx is often used where it can be showcased as a focal point rather than in heavy wear flooring applications.

Frequently Asked Questions

Are onyx slabs suitable for kitchen worktops?

Onyx is softer than granite or quartz, so it is best used where it can be admired as a focal point, such as a statement worktop, island or vanity top. With careful use and proper sealing it can work beautifully in a kitchen.

Can onyx slabs be backlit?

Yes. Onyx is naturally translucent, which makes it ideal for backlit walls, panels and bar fronts. Backlighting brings out the depth and colour of the stone for a truly dramatic effect.
