If they all love Kate Spade, I think it's nice! Is rose gold her thing, or are there Kate Spade necklaces in other metal tones? Personally even if I loved the designer, I wouldn't ever choose to wear rose gold, so that's something to consider.
I think it's pretty. I'd get it if I knew my girls would be into it. None of mine would wear it so I'm going to find something that they'd use and like more. You know your BMs best, do you think they'd love it?
I LOVE Kate Spade for things like handbags, and some of their jewelry. For necklaces though, I really like Kendra Scott. You can personalize each necklace with a different color/stone for the same price, that way you can make it more personal for each of your BMs. Just a thought!
^ Ooh just to piggyback on that idea, monogrammed necklaces were a thing a few years ago...I still think they're very pretty and a lot of people I know would love to have one.
Here is a Kendra Scott necklace similar to the color of the Kate Spade one! You can get a silver or gold chain and plenty of stones to choose from (and it's about $10 cheaper!)
I really love Kendra Scott jewelry and I think the idea of a customized piece is awesome. I just know that the girls would really be into a Kate Spade piece. This is so tough lol
