This is a beautiful sink!  I will warn you though, when installing, make sure to tell whoever is doing your install, DO NOT USE WHITE PLUMBERS PUTTY to seal the drain!!  It will STAIN THE SINK and I haven't found anything to get the stain out.  According to what I've read online (after the fact), clear silicone should have been used.  The plumber who installed my sink was obviously not familiar with quartz sinks.  It makes me very sad, because now my brand new sink, in our brand new house is ruined...unless I can find something to remove these white marks/stains.
