Aperçu du produit
Onyx Rainbow Polished (also known as “Rainbow Onyx” or “Arcobaleno Onyx”) is a rare and dramatic natural stone. Unlike granites or quartzites, this is a true sedimentary onyx, formed in caves over thousands of years. The stone features layers of calcite that create a distinct banded pattern, resembling a painting of a desert landscape or a colorful rainbow.
The defining characteristic of Rainbow Onyx is its Translucidité. When backlit with LED panels, the golden and cream layers glow with a warm, ethereal light, while the darker rusty veins create dramatic contrast. As a professional Stone Manufacturer in China, Caron Stone selects the most structurally sound blocks and processes them into premium polished slabs, reinforcing them with mesh and epoxy for stability.

Foire aux questions (FAQ)
Q1: Can I put lights behind Onyx Rainbow?
Yes! Backlighting is the best way to showcase this stone. The golden and cream areas will glow, while the red veins remain dark, creating a dramatic contrast.
Q2: Is Onyx suitable for kitchen countertops?
We generally do not recommend Onyx for high-traffic kitchens. It is softer than granite and sensitive to acids (lemon, vinegar). It is better suited for bars, vanities, or vertical walls.
Q3: Does Onyx scratch easily?
Compared to quartzite or granite, yes. It has a hardness of 3-4. It should be treated like a piece of fine furniture or art.
Q4: How do you ship fragile Onyx slabs?
Au Caron Stone, we use reinforced wooden bundles and apply extra fiberglass mesh to the back of every Rainbow Onyx slab to ensure it arrives safely.
Q5: Can I use it outdoors?
No. Onyx is a delicate stone. Exposure to freezing temperatures, direct sun, and rain can damage the surface and cause fading.
Q6: What is the price compared to marble?
Rainbow Onyx is considered a semi-precious exotic stone. It is generally more expensive than standard marble due to its rarity and the difficulty of quarrying sound blocks.
Q7: Does it etch?
Yes. Onyx is calcium-based. Acidic substances will etch the polish. We recommend using coasters and wiping spills immediately.
Q8: Do you sell Onyx tiles?
Yes, we can cut Onyx Rainbow slabs into tiles for flooring or wall cladding. However, large slabs are preferred to maintain the continuity of the vein pattern.
Q9: What is the maintenance like?
Clean with warm water and a pH-neutral stone cleaner. Re-seal frequently (every 6 months) if used in a wet area like a bathroom.
Q10: What is the lead time?
We stock blocks and slabs. Shipment is usually within 7-10 days for standard orders.
