It's so wonderful to hear that your daughter loves her new necklace, and how exciting that you're picking up more as gifts. I checked into our collection for matching Strength earrings, but I don't see any that pair directly with that piece. I'm sorry about that. If you'd like, I can have a colleague take a closer look to see if there's anything similar or upcoming, or help you with your birthstone selection.
Thank you,\
