Slight water marks should dry, if the air can get to it, I would be more worried about any damage to the fixing of the stone and or substrate, any idea what it's fixed down to and with ? How has the water been dealt with ?

The water was sucked up with a wet dry vac, dehumidifier has been used it's a concrete floor primed with norcross prime bond,schluter ditra on top and the adhesive was norcros flex rapid and the grout is norcros flex grout I know this as they gave me the invoice The floor feels solid no cracks anywhere it's all dried out now been a month so the question is if it's sealed again will it improve the look

Water marks can sometimes be cut into using a mildly alkaline cleaning solution, we have power clean, dilute 1-10 test one stone and wash over with a white pad, also the impregnator may dull if there was a slight excess , looking like water marks. On darker stones can look like a misting to marbles, this would be the same as above to start, and move on to a stripping agent if required.
How long was the water sitting ,before removed?
Any dark shading?
Do you have any photos?

I will pop down tomorrow and take some photos and yes it looks like slight misting

Would be good to see the photos and comment further , even if possible salts have traced in the cappillaries this also can produce a misting or dullness this could be removed with mechanical polishing, so should be possible to recover, whichever
