Onyx Arco Iris is a Mexican onyx in honey, gold, orange and brown tones. It is used above all for backlit wall compositions, counters, bathrooms and prestigious interiors.
Onyx Arco Iris is a stone for rooms that need warmth and light. The colour palette ranges from honey through gold to orange and brown, often with soft transitions and banded zones. This makes the material appear lively without being restless. Polished, a deep, almost amber-like impression unfolds; backlit, the stone develops its real strength. At ROSSITTIS we stock Onyx Arco Iris for interior projects in which natural stone is deliberately used as an eye-catcher.
The material is quarried in Mexico, among other places in the Zacatecas and Oaxaca areas, depending on the variety and trade designation. Typical of onyx is its translucent structure on a calcareous basis. Unlike a granite or quartzite, Onyx Arco Iris lives not on maximum hardness but on colour, play of light and decorative depth. It is therefore specified above all where the visual effect is more important than an uncompromisingly robust everyday surface.
Technically, Onyx Arco Iris should be treated as a sensitive interior stone. It reacts to acid, is more prone to scratching and calls for a clean substructure as well as careful working of edges and cut-outs. For heavily loaded kitchen worktops or rough external applications it makes only limited sense. Its strengths lie in the prestigious surface, not in a robust utility character.
At ROSSITTIS, Onyx Arco Iris is available as a raw slab, as a backlit wall slab, vanity top, counter front, table top and as a made-to-measure interior fit-out element. The stone works particularly well in bars, lounges, bathrooms, spa zones and reception areas. Anyone planning a calm interior can set strong accents with selectively used partial surfaces without overloading the room.
Our honest assessment: Onyx Arco Iris is not a material for every building site. Anyone looking for robustness, acid resistance and everyday tolerance is on safer ground with quartzite or granite. If, on the other hand, you want warm, luminous depth and a genuine statement character, Arco Iris is a very strong choice in design terms.

Guide values for the stone type, taken from manufacturer and test reports. Natural stone is a natural product — individual batches and slabs can differ. For critical applications, request slab-specific test data.
Onyx Arco Iris is available in a range of finishes. The finish affects appearance, feel and the care it needs.
Polished
Polishing is the preferred finish for onyx — the mirror-smooth surface brings out the material's varied colour character in full. The highest possible colour intensity and deep light reflection. Onyx is acid-sensitive and softer against scratches than marble — recommended for wall cladding and designed visible surfaces, less so for worktops.
Care & fabrication
You should clean and care for Onyx Arco Iris carefully, because the surface is acid-sensitive and comparatively soft. An impregnation makes sense for bathrooms, tables and decorative slabs. Clean only with pH-neutral natural stone cleaners and soft cloths. You should avoid vinegar, citrus cleaners, abrasive agents, intensely coloured stains left over a longer period and hard impacts on edges.
Frequently asked questions
Is Onyx Arco Iris suitable for backlit walls?
Yes, for that the stone is particularly suitable. The warm honey and gold tones gain considerably in depth and luminosity through backlighting.
Where does Onyx Arco Iris come from?
Onyx Arco Iris is quarried in Mexico, depending on the variety above all in regions such as Zacatecas or Oaxaca. In the trade the name stands for warm, gold-orange onyx images from Mexican deposits.
Can Onyx Arco Iris be used as a kitchen worktop?
Only with a clear expectation regarding care and sensitivity. Onyx is more acid-sensitive and more prone to scratching than hard rocks. For prestigious kitchens this can work; for hard everyday use there are more robust materials.
How do I care for Onyx Arco Iris?
Clean the surface with pH-neutral natural stone cleaners and renew an impregnation regularly. Acids, abrasive agents and standing stains should be avoided.
Onyx Arco Iris or a golden quartzite?
Onyx Arco Iris is translucent, softer and more decorative. A golden quartzite is more robust and more suited to everyday use, but does not have the same effect in light. The decision depends on whether you prioritise effect or tolerance in use.
For which rooms is the stone best suited?
It works most strongly in bathrooms, bars, lounges, reception areas and wherever it can be staged as a visual highlight.
What does Onyx Arco Iris cost?
The price depends on the batch, thickness, surface finish and fabrication — with natural stone there is no serious flat rate per square metre. Business customers see prices once their B2B account is activated; private customers receive a complete quote through a fabricator near them.
