Sorry for the late reply, I got the Cement Gray, it looks great! I think it might look better on a black Lumia than the white, but the contrast is so precision, I really have no complaints. As for the lip, it has a great over edge lip, completely protects the display, and allows you to put the phone face down with no fear of scratches.
One thing I will add, is that the case fits extremely tight, infact, I cannot take the case off without the back cover of the Lumia coming off as well! It's not a big deal, as once the case is off you have the flexibility to pull the cover off. There is no "scary feeling" of almost breaking something when pulling the cover off.
