We have to find our control where we can. lol! One at a time is a good start!!
You bring up an interesting question about which jewelry pieces we most easily justify. For me, it's necklaces and earrings. I wear and switch them daily depending on neckline, hairstyle, style of clothing, etc. But, I'm super picky and have a very nice collection. So while I'll buy when I'm tempted, it takes a lot to tempt me.
Bracelets are huge temptations but I restrain myself. When I'm working, they bang against the desktop so I end up taking them off. Plus cuffs and bangles (my favorite styles) get scratched from me moving through life so I'm always taking them in to get polished.

I usually restrict bracelets to my non work life.
Rings are lesser temptations. I have nice pieces and don't crave new ones. Also I usually don't like more than one ring on each hand. So that limits wear opportunities.
Last year, I decided didn't want any more costume jewelry. So, I went through everything and donated, gifted or pitched all of it except except for a very few pieces (and they're getting the side eye as I haven't found an occasion to wear what's left.) My goal this year is to replace most of those items with fine jewelry. My costume items were mostly casual, fun pieces. But, I decided I was big girl and could wear real jewelry casually without losing it. LOL! So I don't know that I'm tempted this year as much as deliberately completing my to buy list.
