A Dupont Circle escalator is now even more expensive than Metro’s already pricey equipment: A ring worth an estimated $12,000 is apparently stuck inside. Alaina Van Horn lost a family heirloom Saturday afternoon while riding the escalator down into the station from the north entrance, as first reported by NBC Washington. She was pulling off a glove when the ring fell off.

“That’s the last anyone saw it,” Metro spokesman Dan Stessel told The Washington Examiner.
