Grease pencils, lead pencils, of course, colored chalk are okay to mark on marble. I suppose fast drying paint is okay too.
What is not okay is felt tip pens, or ink. Those materials will disperse through the stone down to the atomic level. It is common that ink could be seen contaminaring the stone tens of feet away from the oeiginal marking. This does take time but happens surprisingly fast. A magic marker might spread three feet in a couple of days. I found that out to my great dissatisfaction.
While white marble (Carerra as example) does has many naturally occurring greyish to black veins running through the stone, it is very easily discerned what is and is not naturally occurring. An expensive eyesore.
At a trade show I met two owners of a quarry in Italy. Over the next several days we became friends. They most warmly extended me the invitation to lodge at their home so I could observe their production of white marble. Regretfully I did not take the opportunity graciously presented before me.
We run things a bit differently here in North America. Wire sawing isn't nearly as popular for quarrying as in Europe, speed of the actual cut is fine, it's the setup time involved with drilling and setting the wire in the holes. Don't get me wrong, it's used here, just not everywhere like it is across the pond. Down in Texas they use a lot of Vermeer trenchers with carbide teeth. Chainsaws with diamond teeth are popular in harder stones. Us Hoosiers use a version of the chainsaw that wet cuts using a plastic belt with diamond segments embedded in it.
Quite a few in Italy too!
