Carolina is correct here with recommending a Victorian Floor Tile or Quarry tile. They do come in 100x100mm approx and are in a matt finish. Here is another option from Original Style https://www.originalstyle.com/victorian-floor-tiles/ If you require a sample please feel free to get in touch. Best Regards

I stumbled on it a few years ago, then changed phones and couldn’t work out how to use it 😂 😂 you just bring up google, you’ll see in the top right there’s an images icon, click on that it brings up the 2nd screen. Then click the camera icon and add your photo and it will search for the image. You sometimes have to change the narrative ie when I searched for your tiles it came up with rug?! I’m not a fan of Pinterest, I try and avoid it!

They do hexagon zellige tiles here so may be worth a few samples https://zellige-tiles.com/zellige-factory-stock/
