I think everyone's situation is different, so only you can really decide whether you'd wear the ring enough to make it worth buying. So you hopefully will get a better feel for that once you see the ring. I will say that I have always loved jewelry. I didn't keep anything that I don't love. But yes, I have bought beautiful pieces that I never wear! My lifestyle is super casual and I no longer work. We have the daughters' weddings behind us, and those were the dressiest occasions we had. We may go to a wedding every year or two at this point, but most won't be ultra formal anyway. I think I wore a right hand ring to our daughter's wedding in 2019, and that's likely the last time I wore one! I only have a few, and I am saving them for my daughters and granddaughters and maybe selling one or two. I have other special things that I rarely wear that I'll give the girls over time for special birthdays. They likely won't be buying much jewelry themselves, so hopefully they'll treasure a few heirloom pieces.
The reality for me is that I wear a wedding set and earrings (studs or hoops mostly) on a daily basis, maybe a necklace/pendant and a bracelet if going out to dinner or something. I honestly think I could have a capsule collection of 10-12 pieces, and that would serve me well 99.9% of the time! All that is to say that I admire but will buy no more special occasion jewelry, because wearing something once every 2-3 years just isn't worth it.
I would love to have a diamond necklace for just that type of outfit!
