Gets softer as you go up the 24K scale though! Dammit! Someone needs to come up with virtually scratch proof gold with at least 75% content, mix in the super-hard material in the "other" 25%. I'd sign up for that. Then Rolex can take adapt it for their precious metal watches, come up with some fancy UltraHard(On)Gold(TM) name and use that as part of their pitch!
