Cutting marble mosaics

I’ve got a job using marble geometric mosaics about 10 mm thick. I’ve tried several blades to cut these but every one seems to chip and break the corners off the tiles . wet sawing seems to be better but still the same problem.and almost impossible to see the lines. I’ve bought a Montalit dry /wet cutting disk, but still the same problem.does anyone have any advice out there ?
I’m going to buy some plastic strengthening Self adhesive backers tomorrow for the tiles, but is there anything else I should be doing that can help? Any advice appreciated before I wreck 2.5k’s worth of tiles!!

Best to cut mosaic is using the wet saw and a good brand-new blade. When you cut them use a Wedi board under the mosaic. You will get good cuts.

1 Wet saw with plunge control so can score them first or
2 Pull them from the mesh backer and cut one at a time or
3 Cut oversize and grind to size &
4 Some way to reduce vibration & hold them down

Wow what are the make of tile to be that expensive? Or is it a huge area?
