Refined Diamond Sales

As mentioned before, diamonds are only good for weapons. People arnt likely to make anything less than 120. Level 120 weapons require time pieces, which is rarer than diamonds atm. You also get 3 slots, which will be wasted if you dont use it. We all know 1 slot will be a diamond, the other 2 slots, well, primary stats and something else. Getting an advanced primary stat is harder than getting an advanced diamond (on average) so if anything, diamonds are just too common and too stocked up in GMS.
