Yes, you read that right, rings are getting removed.
They simply did not fit well with the rest of both vanilla and TCC’s content, and there are many many reasons behind this decision I will not go into here. What matters is the replacements to rings:
Diamond rings (which increased health) have been replaced by fortitude potions
Ender pearl rings (which acted as item magnets) have been replaced by the tangling pearl
Amethyst rings (which made items glow on your death) have been replaced by the recovery compass rework
All other rings have been removed entirely with no replacement
Quartz (attack damage)
Boring, simple stat boost upgrade, invalidated strength potions
Prismarine crystal (attack speed)
Boring, simple stat boost upgrade
Emerald (increased saturation from foods)
Way overpowered
Lapis (increased experience from mobs)
Way overpowered
Echo shard (healing from mob kills)
Underpowered for an echo shard
Still considering a replacement for this ring variant
These were the gemstones you created by putting gems into stonecutters. They simply served no purpose aside from being another annoying step in crafting.
Replaced with using gems directly in the jewelry table
Base Ring Items
Don’t worry, I’m not talking about rings themselves. Just the rings without gemstones on them. Again, they served no purpose aside from annoyance.
Replaced with using ingots directly in the jewelry table
Pristine Rings
These were a bit annoying to make, requiring 20 amethyst dust. Additionally, once you had the 20 amethyst dust in the table, you couldn’t not make a pristine ring and use all 20 dust. Very irritating.
Replaced with netherite rings giving the double boost to ring attributes
Potion-soaked rings
These were very annoying to deal with when carrying around a ring in your offhand for the attribute. You would sometimes accidentally activate them, causing you to waste valuable potion durability.
Replaced with the much more organic and sensible diluted potions
