Sell my old ring for a new one?

So my fiancé and I got engaged July 2019. We both decided when we were going to get engaged and I went and picked out the ring and then he asked me a few days later. When we got the ring we had to get it resized and we had a few issues with it coming back missing a diamond so that I had to re-order it in the correct ring size and we were getting a lot of pushback and it was making me very upset with the whole ring ordeal. So I wear my ring all the time and sometimes question if I love it because my favorite thing about my ring is a little swirl carriage like design that’s under the diamond and halo that only I can see. Fast forward to today and we walk by the store having a 70% that location is closing sale. I see the ring that I really loved a few years ago still in the case and I asked the lady how much it is and it ends up being the same price that we bought the other ring for. I’m contemplating switching them out that in there but I just can’t do it because I don’t want people to judge or think that it’s irresponsible even though it’s the same price. So we leave and I end up going back a little later and buying a ring for myself in case I did wanna decide this later on because there’s no way I was going to find that ring at the same price ever. I don’t know if I want to actually keep both because I want to wear the new one since it’s more my style. My fiancé doesn’t care he thinks we should sell the old one since I love the new one so much and then just use that money to pay for the new one. He also doesn’t care because he said he’s not the one wearing it, I am. As long as I still marry him we’re good. I also feel funny questioning something that’s so materialistic but at the same time I’d wear forever. I could’ve walked away and note even bought it but it was a 4K ring at 1k... So, should I sell it? Wait on it a bit?
