there is a fellow with a nice raster to vector program that has done quite a bit of 3d engraving in granite, I will try to find the link. If memory serves he was using half round (D shaped) carbide tools he was grinding himself , slow process but loooked really nice

Mach3 have plugin Impact/Laser engraving.You must have impact engraver (solenoid and plunger) with solid carbid tip mounting on Z axes.
You can see http://www.machsupport.com/artsoft/Yahoo.htm , message # 76210 for more information about it.

In years past they used a rubber mask and sandblasted the openings in the mask.

they do it all the time with hand held routers. Diamond bits,lot of water it would be a mess unless you were geared for slop.Ask some questions at a shop that works stone counter tops or search lapidary supply.AL
