Chloe Kim tore up PyeongChang's icy half pipes for the 2018 Olympics, and now she's iced out again for the ESPYs ... rocking a new chain that's worth its weight in gold.
The U.S. Olympic gold medalist recently hit up celeb jeweler Ben Baller for some new bling to wear to the sports award show ... where she's got 3 nominations including Best Female Athlete.
Ben whipped up something special for Chloe -- an 18k gold diamond Cuban choker, with 24 carats in diamonds and weighing 300 grams in gold.
