Best way to level Accessory Crafting?

Idk what earrings require,

3 plates for the 40/45 earrings. Above that they need item crystals too. If you happen to have a lot of intermediate item crystals, you can make half earrings though, everything else is bought from the NPC and you get top tier pots.

Plus since they only take 2 each, you can probably disassemble them and get the monster crystals back, if you're that cheap. I think it's better potential-wise to fuse the non-pot ones though.
