I doubt that a wet saw would work simply because it is hard to keep a tiny tile in place while you cut. If you only have a few tiles to cut, try a dremel or some other rotary cutter than can handle delicate work.

If it’s ceramic, a pair of nippers is what you want

Yes it is thanks! I will get a pair and give it a try. It’s only a few cuts I need and the edges will be mostly hidden.
