You can now buy a Body Vibe replica of General Leia’s ring from The Force Awakens (which she also wears in The Last Jedi). The “signet ring” (per The Last Jedi: The Visual Dictionary) features two blue stones paired in a gold band. It’s avaliable on Amazon for $29.99.
Maybe we’ll see some replicas of the jewelry from The Last Jedi in 2019? Until then, keep your eyes on Etsy…
