I just got the recipe for this from the advanced support NPC in the goldsmithing guild at level 53 the recipe is the standard of earth crystal + 2x aluminium ingot. If the ore is cheap or easy to aquire then this could be a god send for skill ups in the mid 50's. One piece has sold on Hades server for 500k, guessing the guy sold it to his mule.
Speculating the ores are a drop from the new ENM battles, and possibly mining in Newtown Movopolis.
