She is based on the one-of-a-kind Gemma Stone Shopkin that was auctioned off in February 2015 as a benefit for the Toy Industry Foundation. Gemma's hair is white with streaks of very pale purple and blue. Sparkly tinsel is incorporated throughout. Dressed as a queen with a silver ring of pearls adorning the bottom part of her purple crown, Gemma wears a shiny blue and purple ombr dress that seems to shimmer. In addition, she wears a royal blue cape with white fur trim, and a pair of simple purple wedges that have blue diamond heels. She comes with four gemstone-themed Shopkins. Two are visible in the package, and two are in blind bags. Of the two that are in blind bags, there is a chance of getting any one of four different characters, including a chance of getting a limited edition one, Opaletta. She also comes with a diamond-themed purse that actually opens, and a removable cloak and skirt.
