MY front entry has a white granite slab about 6 feet long and some one
area I guess a vein of differnt color causes a black like streak. I
thing I need a diamond disk for my drill. What would you suggest?
Other grits have no effect on it.

what are you trying to do? if you want to cut it out, yes, a cheap diamond
disk in a 4" side grinder will work or a 7" in your skilsaw. don't breath
the dust, it's really bad for your lungs and you're only issued 1 pair.

I don't want to cut it out, just smooth out the dark raised area. It
makes the step look dirty.

you're not going to smooth it out with a normal tool. you need a stone
polisher, sorta like

with a set of diamond pads for it. that will take it from a ground surface
down to a mirror shine, depending upon where you're going to stop.

note that if it's a dark vein, it could go to some depth into the stone. it
may not be on the surface only.
