“Someone has stolen the duchess’ tiara!” isn’t something you usually hear outside of a BBC period mystery, but, recently, someone really did steal a German royal’s diamond-encrusted crown from a German museum’s throne room.

According to Associated Press, a jewel thief has hit the state-run Badisches Landesmuesum in Karlsruhe, Germany. They made off with a gold and platinum tiara that belonged to the late Grand Duchess Hilda von Baden, who passed away in 1952. The tiara was created in the early 20th century and is inlaid with an eye-popping 367 diamonds.

Valued at around $1.31 million, the tiara had been locked up in a cabinet in the museum’s throne room before it was discovered missing on April 29.

Local authorities don’t have any suspects so far, but they are asking anyone who might have seen something suspicious to come forward.
