First, they did not install the stone properly. The dot
method used is not an approved standard.
Second, it's possible they used gray setting material
instead of white. This can cause bleed through in certain
stones.
Thrid. It could also just be moisture, if this is the case
it will go away
In either case, its not good and more than likely will need
to be replaced. I would perform a destructive test to see
whats going on underneath. Il bet they used gray setting
materials

Yes it is seagrass limestone, Im curious as to what caused the cloudy damage between the thinset dots, moisture collecting in the voids under the tiles? and then wicking up salts?

I've seen this before. I can't tell if this is limestone from this picture but it most likley is. We have a demolition service and thats where I encountered this problem before. In our case, and it looks to me like this is the same situation, the installer put 9 dots of thinset on the back of each tile instead of back buttering the entire thing. Also in our case, and most likely in this case as well, he (assuming gender...not politically correct...sorry...not really) didn't even bother to put thinset on the concrete (assuming it is a concrete slab). If he had there would have been a more uniform staining and maybe nobody would have noticed.It's likely poorly bonded to the concrete. I'd rip it out before I tried to fix it but then again, not everybody has a demo service. Having said that, I agree with Baird. I would probably try a good enhancer but managing expectations would be my priority.

Is that limestone? Looks like glue or mastic coming through perhaps. I would twst a few tiles with a good color enhancer. May not remove the issue but may make it easier to live with.
