Just compiling a list for everyone so feel free to add to it for your job.
There is a new Magician Moogle in Ru'Lude Gardens that you can get the quests from. He will give you lvl 30 neck piece and list the requirements needed for each trial. You do not need to be the job quested to unlock the trial though he will only list the jobs you have over 30. Once you complete the trial you will receive a permanent key item job emote and you can toss your neck item from the trial if you want to.
