Is OTHER wrong in the post ? POST : All right, hear me out. Obligatory on mobile/throw away disclaimer. 

My partner (31m)  and I (29f) knew we wanted to marry each other pretty early on, so we had had numerous conversations about what kind of ring I wanted. Not a diamond. Not a diamond. Not a diamond. That's all I asked. While he was designing the ring, he was making jokes about how I didn't want a diamond. I actively didn't want something traditional. Fast forward to him proposing to me, it's a diamond.

Fast forward a couple weeks later we were talking about the ring because it was a little too small to begin with, and I was asking him why he chose to get me a diamond instead of anything else. He said he didn't want to have to explain to people why he didn't get a diamond, that the purchase really represents him and how he values the relationship. He had the ring custom built. He chose everything about the design and stones. I mentioned that the ring is really for the recipient and not for the audience and I think this was discouraging to him because he said he thought I could change my mind about diamonds and we can just get everything changed.

I don't want that, this is the ring he gave me, this is the ring he wanted to give me. It's an immensely beautiful and expensive gesture and I would never want something that he didn't want to give me. But aside from the size being too small, I genuinely do not like the design of the ring and I hate diamonds. I am blown away that he would go above and beyond to make getting me an engagement ring a massive, personal project. That's why I don't want another ring, the sentiment alone does it for me. We basically settled on he should have included me in the process.  He just wanted to make me happy, and he spent a lot of money to do it. (Which is another reason why I didn't want a diamond in the first place.)

Now, I'm picking out wedding bands, the design I want does not match the engagement ring, I do not want to wear them together. 

I don't want to wear my engagement ring at our wedding. It's too small to fit comfortably with another ring on the same finger. I don't want to wear it on my right hand. Point blank, I dont want to.

So, WIBTA if I was honest to those who ask where my ring is? If I said it's not really my style? Any other excuse would contradict the fact that Im probably not going to wear my engagement ring much after this. It irks me that so much about weddings is showboating and I don't want to pretend. I got something I didn't want half because my partner was worried about what other people would think, and now do I have to continue that facade? Both of our mothers know how I feel about the ring. And my partner knows I probably won't wear the ring much after we get married. If that matters at all.
