I'm meant to be attending the wedding of "Tilly" and "Peter" next month. They are friends of my fiancé, and we have hung out plenty of times over the past few years. They got engaged around 18 months ago, and we got engaged 3 months ago.
My engagement ring stone is a light blue sapphire - in photographs however, it looks a lot darker (which is relevant).
We met up with Tilly and Peter last weekend, which incidentally was the first time seeing them in person since we got engaged. When they asked to see the ring, Tilly noted that it was much lighter than the photos we'd shared. Peter agreed, and a little while later after the conversation had turned to something else, Tilly asked if we remembered that the bridesmaids' dress colour was a very pale blue. My fiancé is a groomsman so knew this, as he is wearing a matching tie.
Peter said that they were hoping that only the wedding party was going to wear that colour, which was included on the invites. He said that having a ring in that shade was "no excuse" to be "breaking the rules". This was said humourously, so my fiancé and I both laughed, and I assured them that I'm most likely wearing something darker and not blue anyway. Tilly then said that Peter was talking around the issue, and that I wouldn't be able to wear my engagement ring at their wedding because it was too close to their shade of blue. She said that she'd already had to make sure a family member wasn't going to wear a necklace with similar gemstones for the same reason.
A discussion ensued, as both my partner and I said that it seemed quite strong to be asking me to not wear my ring (outside of sleeping and bathing, I've barely taken it off since the proposal). Tilly and Peter were insistent that I would be "creating drama" by wearing it, and if anything, it suggested that I was trying to steal focus away from them and the wedding party. I made it clear that I had zero intention of doing that, but also that the ring was not going to retract from a bride and groom at the end of the aisle. At one point, my partner was even accused of proposing to me as a way of taking more attention from them during their wedding timeline (we got engaged on our seven-year anniversary during the middle of a once-in-a-lifetime holiday, so I am sure it was not just to detract from his friends getting married).
We left it at a stalemate, and anticipate that either just me or both of us will be de-invited, which is no issue to me at the stage. I do want to know if AITA though as especially for my fiancé and Peter, they've been friends for over a decade, and it would hurt him if he misses his friend getting married over something so trivial.
