Maybe these will help you in making lemonade out of the lemon (which I don't think it is)Where else are you putting the beige tiles? And where are you putting the mosaic.Perhaps ramping up the black in accents will legitimize the beige and blackhttps://www.houzz.com/photos/jane-lockhart-interior-design-kylemore-model-home-dublin-traditional-bathroom-toronto-phvw-vp~1267669

if you lighten the cabinets etc, then the stone will appear more prominent. if that is what you want, that is fine. I sensed that you did not like the current counter. I would contact a marble/granite installer to see if they think that the cracks can be filled and polished out. it is pretty common to do this on new installations if it is feasible. they may try to charge you as as much as you would spend on a fabricating a counter out of a new slab if they did not do the original installation.

When it comes to lightning it pays to spend a bit more. I see it as an investment and it usually is such a great conversational started

I forgot that curved countertops are a possibility within the kitchen. Makes it look classy.
