My heart says it's perfect but my sister says "it's okay"

Okay I found this ring on etsy & as soon as it popped up on my screen I was just like "holy guacamole! that's the ring for me" the thing is, when I asked my sister about it she said "it's okay lol" so I'm a bit self-conscious about liking it so much. She is a bit more traditional than I am. My ex got me a very traditional ring & I kinda hated it so I know that's not for me.

The first photo is the ring I swooned over & the second photo are the colors I might prefer, with blue I'm the center & purple/pink on the sides? In not sure. If I go with blue I would get definitely get yellow gold. If I get the pink one I would stick with rose gold because it is absolutely lovely.

Anyways I'm just looking for a bit of advice & opinions. Thanks 😁
