If you are a Game of Thrones fan or know someone who is, this is the perfect gift. Pandora has a line of jewelry dedicated to the show, and while I think they’re pretty cool I thought GoT peaked a while back?

This ring has the form of an astrolabe, a scientific instrument that preceded the  sextant and was meant to calculate latitude. So this ring has form but not function, as it were.

The site explains, “Show your strength with the Game of Thrones Spinning Astrolabe Ring. This spinning ring from the Game of Thrones x Pandora collection is plated with 14k gold and features spinning bands with intricate detailing, reminiscent of a true astrolabe. The two ring bands are connected by pins, allowing for movement. The intricate detailing adds a mythical touch together with the sparkling cubic zirconia. Inspired by the history of Westeros, it’s the perfect piece for the Game of Thrones fan in your life.”

This is priced at USD$115.
