Bridesmaid Gifts: Coorindate Necklace

I work with a girl who was gifted a coordinate necklace as a bridesmaid in her best friend's wedding. I thought this was the sweetest gift. It was the location of where they met. She said that if she could do her wedding over, she would use this as a gift for her bridesmaids.
I absolutely love the idea and was thinking of incorporating it as a gift for my girls. However, I've been having a hard time. My bridesmaids consist of two sisters, one sister-in-law, and two good friends. I feel like this would be difficult to do as a "place we met" for my sisters and his sister, because it would be something like the hospital I was born at (youngest) for my sisters, then his parent's house for his sister. Does this sound stupid?
I need some advice and opinions! Picture below of the necklaces!
