Once you get to Blosk, if you complete a quest for the weaponsmith there (quite simple, kill a few lab rats in the back of her store), she'll offer to forge some custom items for you. Each item requires 3 fine steel, 2 focusing crystals, and a few beautiful crystals, I think. She'll build you a Radiant Plate (which requires 2 gold bars in addition to the above ingredients), a Radiant Shield (2 emeralds in addition to above), Radiant Vambraces, or a Blessed Halberd. All are great items, and the Radiant Plate is one of the best armors in the game (in my opinion, a toss-up between it and the Emerald Chestguard).
