Pentagold 3 cm

I just saw some of this Pentagold which has multiple Colors (http://www.g640.net) in it--yellowish gold, white, etc. The 3 cm looked different from the 2 cm. This was the only Pentagold I have seen after looking in multiple Granite (http://tanbrown.org) yards. Does anybody have experience working with it or know how it "wears?"
Thanks!
