Mattel and American Girl are adding a little A LOT of sparkle to the holidays with one-of-a-kind collector dolls covered in thousands of Swarovski crystals.

There are three dolls, featuring formal gowns and accessories that were hand-embellished with more than 5,000 Swarovski crystals and crystal beads in 24 colors. The bidding for each American Girl collector doll starts at $5,000, with 100% of net proceeds going to the First Responders Children’s Foundation. Mattel and American Girl are also donating more than $1,000,000 in retail value of toys to the foundation’s Toy Express program, including 18-inch American Girl dolls and products from Hot Wheels, Barbie, and Mega Bloks.
