Could the mosaic be this California Gold that I found on efloors.com?

If you can't find exactly what you want, you might see if you can find two different combos of tile...one lighter and one darker, and mix them yourselves to get a greater variation in color. Just make sure they are the same dimension...length, width and depth.

This one looks pretty colorful...

they look like they are about a 4 inch square block and you might not find and actual pattern sold like that you may need to buy a few different types of tiles to get your look you want

Is there any designer or installer info on the houzz pic?

could the smaller tiles be a porcelain look alike??

That strongly resembles Marazzi Imperial Slate Black/Rust mix mosaic

The tile you like is 2" x2" slate mosaic tile that is sold almost any where. I've seen it at Home Depot & Lowes. It's fairly inexpensive and easy to install.

I was going to suggest Meredith Tiles--but it turns out they've gone out of business at least five years ago. Too bad--they had wonderful tiles...
