Can you explain some options and why they are used?
Jewelcrafting: Use Remaining Gems? I can't even guess.
Mailing: Mail gems to alchemist ( Is this just mailing like tiger opals, sunstone, etc?)
Mail Gems to Banker (Is this crafted gems? like you craft bold primordial ruby and it sends to banker?)
Mail Rare Gems to Banker ( Are these all the rares from prospecting? I.E. Imperial Amethyst, River's heart, Vermillion Onyx?)
