Rare ring pricing guide?

Hi,

For example i have mediocre roll ring with good attributes, mediocre ll, nice str and dex, mediocre all res, mediocre extra res. What properties are needed for rare rings of

Vex+ value and what rolls?.
I want to learn how to price my rings. Thanks.

edit: Oh sorry, not a help with value but getting an idea in general what actually does have high value

thanks man. Now i have max sigma 1.24 decent what does that mean, how much approx is that?

Sorry if it was misleading, thought the site would suggest a value too.
I also struggle to put a price tag on rare and crafted Items.
You could just run a price check on it .

I think if that website tells you it's "decent" it's probably not worth anything for trade.
I think it's pretty hard to find buyers for anything but really good rare rings, because everyone tends to have decent rares lying around.

I run my entire collection of rare rings through that site keeping only ones closing to green. I am left with just few rings . But it feels so relieving to get rid of garbage.

The only rare rings I tend to keep are 1: dual leech rings with other various stats (attack rating, resistances, strength, dex, life, mana) and 2: 10 faster cast rate with various stats (strength, dex, resistances, life, mana)
