A 1,200 × 600 × 20 mm (47 × 24 × 0.8 in) onyx top has a nominal mass of roughly 34.6–38.9 kg (76.2–85.7 lb) at 2.4–2.7 t/m³, before substrate and packing. Apply that range only after the slab, repairs and support are approved; “onyx” alone does not set structural safety.
What information should an onyx table quote include?
Approve the slab face, repair map, translucency, thickness and rigid support as one package before cutting.
| Item | What to confirm |
|---|---|
| Material label | Onyx is treated here as a commercial stone label; it is not a mineral guarantee for every named slab. |
| Onyx names | Options include Green, Pink, Blue, Honey, Persian, Rainbow, Tiger, Imperial Gold and Peacock Onyx. |
| Nominal mass | 34.6–38.9 kg (76.2–85.7 lb) at the stated size and 2.4–2.7 t/m³, excluding support and packing. |
| Backing and base | Specify which layer controls surface repairs and which rigid member carries the top. |
Which shapes expose onyx most kindly?
Simple outlines reduce cutting risk around a repaired slab.
Rectangular onyx tops
A rectangle gives a straight seating edge and efficient slab crop. Mark fissures and the preferred face before cutting. Resolve the replacement-top support with the edge.
Round onyx tops
A circle changes perimeter waste and may force the diameter away from a repair. Keep any light route inside the base footprint. Review the round marble format for proportions.
Oval and square onyx tops
An oval needs a banding-aware template; a square concentrates care at four corners.
The supplier image is one appearance reference, not stock proof.

Is onyx suitable for a frequently used coffee table?
It suits a controlled living room when the approved slab is backed, supported and used with care; it is less forgiving where children or heavy objects routinely hit the edge.
| Feature | Why it matters | Approval point |
|---|---|---|
| Translucency | Natural variation and repairs become more visible with backlight. | Inspect the slab behind the proposed light panel. |
| Fissures and fills | Repair loss can become a sharp edge or a visible line. | Map repairs and agree how they will sit in the finished crop. |
| Acid exposure | Calcareous commercial onyx can react to acidic drinks and cleaners. | Use coasters and confirm the care method for that slab. |
How should buyers choose among named onyx colours?
Choose by the physical slab first: two slabs with the same trade colour can differ in banding, translucency and repairs.
| Colour family | Examples | What to check |
|---|---|---|
| Warm | Honey, Imperial Gold, Orange Flower | Warm names do not promise the same intensity or translucency. |
| Cool | Blue, Green, Peacock | Approve the slab under room lighting and with the intended backing. |
| Pale | White Jade, Ivory, Athens White | Check marks near the seating edge and any visible repairs. |
What should an onyx coffee-table quote itemise?
The quote must identify the slab and every layer beneath it; a stone-only price does not show whether the table can carry its own span.
| Minimum order quantity | 1 piece |
| Production period | About 20 days production + about 30 days shipping; production starts after deposit receipt and drawing confirmation |
| Dollar range | Coffee-table quote on request through Contact |
Require slab face, repairs, thickness, edge, backer, rigid support, base, lighting and destination on one quote.
How does onyx differ from marble and travertine in furniture?
Onyx is a separate commercial family here; it should not inherit marble care or density simply because some suppliers sell it beside marble slabs.
| Stone | Distinct condition | Table choice |
|---|---|---|
| Onyx | Translucency, fissures and repairs vary by slab. | Approve backing and lighting slab by slab. |
| Marble | Carbonate-based and generally acid-sensitive. | Use it when veining matters and coasters are accepted. |
| Travertine | Pores or filled voids shape the surface. | Approve fill colour and edge treatment. |
How should an onyx coffee table be cleaned?
Clean the approved surface gently and keep moisture away from unprotected edges, repairs and any electrical cavity.
- Wipe loose grit before applying a cloth to the face.
- Blot spills with a soft cloth and avoid acidic cleaners.
- Dry around seams, fills and lighting apertures.
- Test sealer and cleaner on an unseen part of the slab.
What should be settled before an onyx table is cut?
The slab’s condition and the support beneath it matter more than the commercial colour name.
Does an onyx coffee table need backlighting?
No. Backlighting is only an option when the approved slab is sufficiently translucent and the light source can be accessed for service. Many commercial onyx tops are used without it. If lighting is added, approve the panel, heat clearance, wiring route and base cavity before fabrication, because a thin fissured top should not become an electrical enclosure by accident.
Is onyx more fragile than marble?
Some commercial onyx slabs contain fissures, repairs or thin translucent zones that need backing, but a blanket comparison cannot rank every slab. Marble also varies. Judge the physical slab, the span and the proposed substrate together. A mesh reinforcement controls surface repair while a rigid frame provides structure, so ask which function each layer performs.
Which onyx colours are available?
Amazstone offers White Jade Onyx, Green Onyx, Pink Onyx, Blue Onyx, Honey Onyx, Persian Onyx, Ivory Onyx, Rainbow Onyx, Tiger Onyx, Imperial Gold Onyx and Peacock Onyx, among others. These are commercial trade names, not a colour or translucency guarantee. Approve the slab face and its repair map before production.
Where should an onyx buyer go next?
Start with the room category, then follow the material, shape or lighting decision that remains unresolved.
