So how are you supposed to get emeralds? There's no emerald card I've seen yet and I've finished every quest in the first page but the villager one (because emeralds) and the 1000 pink dye one. The chemistry quest says making emeralds with minechem is 'easy' but the only way to get all of the materials for emeralds is by decomposing emeralds or by using fission/fusion reactors which seems a bit much. I've got several quests, including the entire essentialcraft page blocked by diamonds. I got 8 free emeralds by completing the emerald chemistry quest by getting two emeralds from a thaumcraft bag and decomposing one for the parts and submitting the other, but the 8 ran out immediately without actually being enough to finish any of the other quests. Not sure what to do here.
edit : Huh, looking through my quest book carefully, it looks like I was given an emerald card and somehow lost it in the shuffle at some point. I just cheated myself another one and it's all good now.
