Jimi looks good anywhere.
A metamorphosed limestone, I expect any calcium carbonate would react the same. Instead of micro-fracturing the surface like granite, marble is ablated.
Like @marmak3261 observed with Corian, I noticed tiny sparks - which turned out to be a very fine hot ash.
By the feel of my fingernail I would guess about a 100th" depth. The surface is bleached of all pigment and will receive color well. In this case trusty Krylon flat black spray.
What else do I have around here…?
