Your mother reminds me of my mother in law, who was so worried that rubies were bad luck, that I almost had to have a different engagement ring to the one I wanted to placate my husband's mother. Has to be said, it wasn't the best start to our marriage plans. I wondered where else his mother was going to end up messing with what we wanted to do. Anyway, turns out she wasn't that bothered and I do have a ruby engagement ring.
