Onyx Stone for Bold, Glowing Interiors

Onyx: the glowing statement stone

Onyx is a banded stone formed from mineral deposits, and its layers can be translucent, so it can glow when lit from behind. Its colours include honey, amber, green, white, red and multicolour blends, with swirls and bands that no designer could draw. Natural Stone Cart supplies onyx slabs for feature walls, bar fronts, reception desks, table tops and luxury interiors.

Onyx colours: black, pink, green and white bands

Onyx is one of the most luxurious and elite semi-precious stones, formed by black, pink, green and white parallel bands. It has been used since ancient times. We supply onyx slabs and cut-to-size tiles, and thanks to its transparent properties the stone is beautiful when lit from behind.

What makes onyx different

Onyx is softer than granite and more sensitive to scratches and acids, so it is mainly used on walls, decorative surfaces and low-traffic areas. Its beauty is in the pattern and translucency. When backlit with LED panels, thin onyx slabs glow warmly and make a space feel special. For this reason, onyx is often found in hotel lobbies, restaurants, bars and luxury homes.

Because patterns vary a lot, we show real slab photos so you can choose the exact slab.

Colour and pattern

• Honey and amber: warm, golden bands, great for lighting.
• Green onyx: fresh green with dark patches.
• White onyx: soft, creamy translucency.
• Red and orange onyx: bold, fiery bands.
• Multicolour onyx: dramatic mixes for statement pieces.

Slabs can be book-matched so that the pattern mirrors across two or more slabs, creating a striking wall.

How onyx is installed

Onyx is usually installed as thin slabs, often reinforced with a fibreglass or resin backing for strength. Fixing should be planned by an experienced installer. For backlit walls, discuss the lighting system early, because LED panel size and heat control affect the design. Always use a compatible adhesive, since some adhesives can discolour translucent stone.

We can supply backed slabs or cut-to-size panels to your drawings.

Care

Protect onyx from acids, abrasive cleaners and heavy impacts. Wipe with a soft cloth and a pH-neutral cleaner. Seal the stone, because onyx can absorb stains. Avoid hot pots on onyx surfaces. With simple care, an onyx feature wall stays beautiful for many years.

Packing and shipping onyx

Onyx is fragile, so we pack slabs in strong wooden crates or frames with protection on edges and corners. We ship from Mundra and Kandla and share photos of packing and loading. Customs classification is often under heading 2515 for blocks and 6802 for worked slabs, and your broker will confirm. Ask us for current availability, as onyx supply is limited compared with granite and marble.

Planning your container and shipment

A good load plan saves money. A standard 20ft container can usually carry roughly 25 to 28 tonnes, but the exact limit depends on the shipping line and on road and port rules in your country. Onyx is fragile, so we use extra protection and plan carefully. We calculate the load by weight and by size, so you do not pay for space you cannot use. Mixed containers are possible: you can combine different stones, sizes or products, which helps wholesale buyers keep stock varied.

We ship from the ports of Mundra and Kandla in Gujarat to ports around the world, and we share photos of the loading so you can see how your stone is secured. Sea freight time depends on the route and the shipping line, and we give you an expected time with each quote.

Export documents and customs for onyx

Clear paperwork keeps your container moving. For every shipment we prepare the commercial invoice, packing list and bill of lading, and where your country needs it, a certificate of origin and other documents. Packing wood is treated for export, and we can supply the treatment details if your port requires them. Onyx is generally classified under HS heading 2515 for blocks and 6802 for worked slabs; your broker will confirm.

Customs rules and duty rates differ by country, so please confirm the exact classification and duty with your customs broker or the official tariff of your country. If you tell us your port and clearing agent, we will send documents in the format they prefer, and we are happy to answer their questions directly.

Quality control, inspection and claims

Before packing onyx, our team checks size, thickness, surface, colour and edges. We separate pieces that do not meet the agreed standard, and we explain what is natural variation and what is a defect. You are welcome to arrange third-party inspection before loading, and we cooperate fully with inspectors.

If a problem is found when the container arrives, tell us quickly and send photos of the packing, the damaged pieces and the container condition. We look at each case fairly and work with you on a solution. Good packing, honest photos and clear agreements keep claims rare.

Working with architects, builders and fabricators

Professional buyers need more than a price. Architects want samples and clear specifications. Builders want the right quantity on the right date. Fabricators want slabs that cut well and match across a project. We support all of them with real photos, written specifications, labelled packing and honest delivery dates. Onyx projects usually need photo approval of every slab, so we share slab-by-slab photos.

For larger projects we can produce in batches, keep reference samples, and share progress photos. If you send a bill of quantities or drawings, we check the details and tell you early if something needs a decision, such as the size of a piece or the thickness of an edge.

Natural variation: what to expect

Onyx is a natural material, so no two pieces are exactly the same. Colour, grain, veins and small marks vary from slab to slab and from lot to lot. This variation is part of the beauty of the stone, and a good design plans for it. To reduce differences on a project, buy all material from the same lot, keep slabs in bundle order and lay pieces out before fixing them.

We tell you honestly what to expect from each stone, and we send photos of the real lot. If your project needs very tight colour matching, tell us early, and we will select accordingly.
