Need suggestions please

Have you looked on Etsy?

I did something similar for my bridesmaids: our bridesmaids dresses were blue with a beautiful oversized floral pattern that pulled in additional shades of blues, purples, and champagne. After doing a little general snooping for 1. what color each girl would prefer and 2. what type of jewelry each would most likely wear again and again I came up with a solution: I chose a variety of pieces from the David Yurman "Chatelaine" collection in the Amethyst and Blue Topaz colors. The Blue Topaz and Citrine could be what you're looking for, or they have SO many other options on their site Of course all depends on what you like and your budget. Good luck!!

Have you looked on Etsy? Does it have to be the exact same set, or can it just be similar?

Have you tried making it? Such as finding just a charm that's blue or yellow and adding it into a necklace chain?

I also suggest Etsy, they a great variety.

I bought on Etsy. I bought each bridesmaid the same set, it was lever back earrings and a simple drop necklace, they were made with Swarovski crystals and you could choose the colors. There were many different styles of necklaces and earrings from that seller, so I mixed and matched and she boxed each set together. I’ll see if I can find her info.
