I discovered this remarkably accurate Japor Snippet Pendant on Etsy for just $20. It's made of polymer clay and acrylics and the cord is adjustable making it wearable for most anyone. This is definitely the best representation of the necklace Anakin gifted Padme I have found yet. What a beautiful way to display your love for the couple who started it all!
