Make a bold statement with our Onyx Black Marble Effect Polished Porcelain Tile. Measuring a generous 60x120cm, this large-format tile recreates the deep, dramatic veining of natural black onyx, finished with a high-gloss polished surface that reflects light and adds instant depth and luxury to any room.

One note so this doesn't backfire: your onyx pages currently read very similarly to each other, which Google can treat as thin/near-duplicate content. I've kept this one black-specific on purpose — if you want, I can do the same rewrite across the rest of the onyx range so each one targets its own colour terms instead of overlapping. I can also hand it back as paste-ready HTML matching your Focal theme. Want either of those?
