Cutting split face tiles

We are thinking of buying the Silver Grey Quartz split face tiles to decorate a wall in our newly refurbished kitchen. What should we use to cut the panels where required. An we want to hand a heavy Wall Art plaque over the quartz how would we best secure the hanging nail please?

Any natural stone tile will need to be cut using a good quality Diamond tipped cutting blade.

Where fixtures and fittings are to be installed onto the wall, always follow the manufacturers recommendations for suitable wall fixings.
