Onyx slabs supplier to the UK trade.

Onyx is the showpiece of the Turkish stone range — honey, amber and green-toned, banded, and prized for one property the other stones don't share: translucence. The Taurus mountains supply much of the world's onyx. Karpat sources it block-by-block, wholesale to UK fabricators, interior specifiers and hospitality fit-out, delivered duty-paid. It is a small-batch, project-matched material — never a stock line.

Specifying onyx

Plan against the block.

• Tone — honey, amber, green, ice (block-dependent; sample-approved).
• Format — resin-backed slabs and tiles, cut-to-size panels, backlit-ready sheets.
• Finish — polished is standard; honed on request.
• Continuity — bookmatch / sequential panels reserved from one block.

Lead time depends on current block availability at our producer network, so onyx is best sourced against a confirmed specification and timeline. Onyx enters Great Britain duty-free; we deliver duty-paid in GBP, or supply CFR/CIF for buyers with their own forwarders.

How we source

Producer-matched, project-specified.

Send the tone, panel sizes, quantity and whether the run needs to bookmatch. We approach Taurus-range producers on your behalf, confirm against available blocks, and dispatch samples ahead of order confirmation. Every shipment carries proof of preferential origin (declaration on origin, or EUR.1), CE Declaration of Performance, and the applicable BS EN test reports.

Specification & supply

Onyx formats, loads and lead times.

Onyx is supplied as polished slabs and cut-to-size panels, usually alongside marble in a mixed container.

Container loads

Stone loads by weight, not volume: a 20 ft container carries about 25 tonnes, so thickness sets how many square metres fit. Figures are approximate and confirmed line by line on every quotation.

Supply

• Lead time — stock items about 2–3 weeks order-to-door, cut-to-order 5–6 weeks, bespoke 6–10 weeks; a firm window comes with every quote (trade terms).
• Samples — a sample pack goes out with the quotation, and before shipping we send photographs and a slab or crate list of the actual material allocated to your order.
• Delivery & offload — delivered duty-paid to your yard or site and invoiced in GBP. Crates and bundles are offloaded by your forklift as standard; truck-mounted forklift or crane can be arranged. You can also collect from our warehouse at the Port of Tilbury or the Port of Liverpool.
• Ordering — from project quantities to full 20ft containers; smaller orders travel by groupage, and containers can be mixed across colours, sizes and finishes. 60% with order, 40% against shipping documents within 3 banking days.

Common questions

Onyx — what UK buyers ask.

Can onyx be backlit?

Yes. The lighter, more translucent onyxes let light through at 2 cm, and the effect varies from slab to slab — ask us for photographs of the actual slabs before committing.

Is onyx suitable for floors?

Onyx is softer and more delicate than marble. It is used for walls, bars, reception desks, feature panels and vanity tops rather than for floors that take heavy traffic.

What does bookmatched mean?

Consecutive slabs from the same block are opened like the pages of a book, so the veining mirrors across the joint. Order them as sequential pairs and they are cut, numbered and packed together.

Is there a minimum order for onyx?

Onyx runs from project quantities to full 20ft containers; smaller orders travel by groupage. Onyx often travels in the same container as marble or other stone.
