Hi,

Unless I'm mistaken, you can't evolve items from D->C or C->B as the stones currently don't exist. If you want to evolve higher grade equipment, your best chance is to get B grade equipment from maps (or even A or S if you're lucky) or buy A or S grade equips from the shop (using gold and gems respectively). I hope that helps
