This ring should be uncommon because the ring of warmth is and it gives resistance to cold damage and another thing.

Fire resistance.

Also the Periapt of Proof Against Poison grants immunity to poison damage and condition, doesn't need attunement, and is a rare item.  Much stronger than option 7 of this item. 

Just because two things are rare doesn’t make them equally rare. The Periapt of Proof Against Poison (which I’m going to call PPAP) is probably rarer, but not quite very rare. But yes. It is much better.

Combine the ring of Psychic resistance with a totem warrior barbarian for resistance to everything

already did also adeded in mantel of spell resistance

 that is what i was thinking for my character when i came to this page

Ten resistance options, people tend to have ten fingers, someone with one of every resistance ring could, in theory, wear all of them.

Only could attune to 3 at a time, but, tiu can wear unattuned rings as, say, cosmetics to show off.

Or maybe to confuse which 3 resistances you have.

Ring of Resistance maybe should have varying rarities like other items like Ioun stones. Poison resistance is far weaker than say acid, fire, or cold resistance (not even as good as a ring of warmth which is uncommon), especially considering the Periapt of Proof against Poison is also rare, gives total immunity to poison, and doesn't ever require attunement. I might even go so far as to say all rings of resistance would be uncommon.

Fire resistance.

The Brooch of Shielding is also a straight upgrade to the Ring of Force Resistance while only being uncommon rarity. 

Agreeing with all the folk saying Ring of Warmth & Brooch of Shielding neeed errata to make them Rare.

This straight up doesn't require attunement???

Craft one for each digit

So am I the only only slightly confused by the 2024 Ring of Resistance attunement change?  I'm guessing its a mistake given removing attunement would be huge for these rings.  Also, while the general item entry has no attunement, every specific ring entry (Ring of Fire Resistance, Poison Resistance, etc) does list attunement as a requirement. Maybe they wanted to allow for other lesser rings of resistance that might not require attunement in the future?

Seems to be a bug in the DMG since if you hover over the each individual ring of resistance type, it does say it requires attunement

This is one of the only ways in the game to get resistance to force damage; it's classified correctly for sure
