Here's a rough breakdown:

Level 87 for Coronets (+2 skills, and you can also get 3-socket blues)
Level 92 for Circlets (+2 skills, but they can NEVER give 3-socket blues)

Amulets at 93 is the sweet spot for crafting, since gambling + crafting with a level 93 character will give you access to the best mods.
If you only gamble & don't craft, Amulets are best done at level 95+

Rings as far as I know can be rolled well even at 74+
