The two sentences in the middle are correct, however they have nothing to do with what I said. Hardness is not just a function of gold percent, it is also related to what you alloy it to and how you alloy it.
Look at some of the work Apple has been doing for example on 18k gold. ( I can’t post links but it’s easy enough to find)
