Hi Sswagonman,
which particular material is your trouble? Just the gems or 5* materials in general? However, the usual source for them are the loot missions in region 5. They give you a guarantee for a little gold, silk or damascien steel and also a little chance for gems and, even rarer, tablets.
However, you need to be patient. There often are also daily offers for rare materials in the shop, but it will take months until you will have forged all items for all your heroes.

Sorry, I just didn't realize what's the matter. "Pieces of Silver" is story mission 25, isn't it? The problem is you can't farm rare materials, because you haven't unlocked the Region 5 loot missions. In this case you'll need to keep trying, train your heroes and rank them up. 5* gear is a thing for players who are close to completing the story. Good luck!
