First, don’t think this is about that massive blue-diamond necklace Kate Winslet donned for the 1997 movie Titanic. This necklace heist happened over the weekend to a real necklace worn by a survivor of the Titanic’s 1912 sinking.

While on display at Copenhagen’s Tivoli Gardens amusement park as part of the traveling “Titanic, the Exhibition,” a necklace believed worn by wealthy Briton Eleanor Widener was nabbed, according to Musealia, the company that owns the exhibit.

Officials believe the theft was the work of an amateur, as the necklace’s value of about $19,000 doesn’t signify the most expensive piece of jewelry in the exhibit. Even still, thieves made off with the gold-plated chain without tripping the alarm. But selling the piece will prove tricky, as the necklace is well known internationally. Musealia has put out a $1,000 reward for information on the theft of the Widener necklace.

The Widener family was reportedly one of the wealthiest on the Titanic‘s maiden voyage, which ended in the deaths of more than 1,500 passengers when the ship hit an iceberg on its way from England to New York.
