Velluto Onyx Polished Marble Slab 76863

Onyx slabs are best used for statement interiors where the stone is intended to be a focal point. Starel’s onyx slab range includes expressive materials such as Jurassic Green, Lavanda Violet, Velluto, Mint Green and Cashmere Onyx. These slabs are suited to backlit feature walls, powder room vanities, bar fronts, splashbacks, decorative panels, furniture details and luxury bathroom features. Onyx is chosen less for everyday practicality and more for depth, translucency, colour and visual drama. It should be specified carefully, especially where lighting, support, handling and fabrication need to be planned before installation.

Yes, many onyx slabs can be backlit because onyx is known for its translucent quality. When the lighting is planned correctly, the slab can glow from within and reveal veining, colour layers and mineral movement that are not visible in ordinary light. Backlighting should be designed early with the fabricator, lighting designer and installer because thickness, backing, LED placement, diffusion, access and fixing method all affect the final result. Not every onyx slab transmits light in the same way, so the exact slab should be tested before fabrication where backlighting is critical.

Onyx can be used in kitchens, but it is usually better suited to decorative or lower-impact areas than everyday working surfaces. It is softer and more delicate than many other slab materials, and it needs careful sealing, handling and maintenance. For a kitchen, onyx may be better used as a feature splashback, bar front, display island panel or decorative surface rather than the main preparation worktop. If the customer wants a practical, lower-maintenance kitchen worktop, quartz is normally the safer recommendation. If the customer wants a showpiece, onyx can be exceptional when specified correctly.

Choose onyx by looking at the exact slab, not just the material name. Onyx varies heavily in colour, translucency, banding, opacity, veining and mineral movement. A slab such as Lavanda Violet may suit a soft, expressive bathroom, while Jurassic Green or Mint Green can create a much bolder feature. If the slab will be backlit, ask for the material to be reviewed with light behind it before final approval. For fabrication, the customer should confirm the visible face, orientation, joins, cut-outs and whether the design depends on a particular section of the slab.

Yes, onyx needs careful sealing and maintenance. It is a natural calcareous stone, so acidic products, abrasive cleaners and harsh chemicals should be avoided. Use pH-neutral stone cleaners, wipe spills quickly and protect the surface from cosmetics, perfumes, wine, citrus, oils and aggressive bathroom cleaners. Onyx is often selected for luxury bathrooms, powder rooms and decorative surfaces, but it should be treated as a premium feature material rather than a hard-wearing utility surface. The right care plan should be confirmed by the fabricator or installer based on finish, location and exposure.

For Starel’s slab listings, cut samples are generally unavailable. With onyx, this is understandable because each slab is highly individual and often selected for a specific face, colour pattern or translucent quality. A small cut sample may not represent the final slab accurately, especially if the stone has strong banding or dramatic variation. Customers should view the slab in person where possible, request full-slab photos, ask for video, and, for backlit projects, ask whether the slab can be shown with light behind it. This gives a more useful understanding than a small sample.

Yes, travertine slabs can be supplied for trade, fabrication and bespoke interior projects, subject to stock, slab size and project requirements. Travertine is well suited to vanity tops, splashbacks, bath surrounds, fireplace surrounds, wall cladding, shelving and architectural details where the warmth of natural stone is part of the design brief. For larger orders, the Starel export notes trade pricing may be available for full bundles, complete batches or larger quantities. Designers, fabricators and contractors should confirm slab dimensions, finish, surface condition, delivery destination and installation environment before reserving or purchasing.
