The main way currently to get Wrath gems is to prospect Wrath ores, usually Saronite. Prospecting a stack will yield an average of about one blue-quality gem, and while other ores may look more attractive, I've had trouble finding them in volume. Now that the cooldown has been removed, any jewelcrafter can make an Icy Prism with nothing more than a Frozen Orb and a couple of cheap Wrath green gems. Each prism will yield a couple of blue-quality gems, rarely a Dragon's Eye, and even more rarely, an epic gem.
The Dragon's Eyes don't look like they'll be usable for much, but considering the price of Frozen Orbs, the blue and epic gems certainly look like they're worth making the prisms for. One thing to note: The prisms are unique, so you need to open one before you can make another. If, like me, you had stockpiled almost a thousand Frozen Orbs in Wrath just in case they ever became worth anything, this means a lot of clicking.
