white will also have scratches, just not so obvious.

how about black galaxy granite... ?

will it have this same problem also?

hmmm....Black Galaxy.......Nice piece. It is very solid and durable. Very hard material and should not be scatch easily. But advise to maintain it as dry as possible. Though water mark will disappear after sometime, but if you take closer look, those shining metallic content will oxidize when come it contact with water for too long and become dull; yellowish like unpolished. Choosing Black galaxy should go for small little sparky spot that spread evenly, not those with big patch of shining metallic content. galaxy are not blue pearl or emerald pearl which the shining metallic content should be bigger and evenly spread

The problem with white is that it will turn yellow for the water spots. I've seen it at a friend's place, his basin is made of solid surface, the area where the water drips has a yellow streak. It also stains, if you have a blue wrapper and you leave it there, the color will stain your white solid surface ....
