French authorities have launched an investigation after burglars stole around 20 rare pieces of jewelry worth an estimated €4 million from the Lalique Museum in Wingen-sur-Moder, northeastern France.
The break-in occurred in the early hours of Sunday, with the masked thieves targeting the museum’s jewelry gallery before escaping with valuable works linked to renowned French jeweler and glassmaker René Lalique. No arrests have been made, and investigators are reviewing surveillance footage to identify the suspects.
Thieves Targeted the Jewelry Gallery
According to investigators, the burglars forced their way into the museum at around 5:30 a.m., smashed six display cases and stole approximately 20 jewelry pieces. The stolen collection is currently valued at up to €4 million.
Officials believe the perpetrators knew exactly where to find the most valuable exhibits. Although the museum’s alarm system was triggered, the security company’s verification process took time. A cleaning employee arriving at the museum discovered signs of the break-in and alerted the gendarmerie.
Police Review CCTV Footage
French police are now examining CCTV recordings and other forensic evidence as part of the investigation. Authorities have declined to reveal details about the suspects’ escape route, the tools used during the burglary or whether they believe additional accomplices were involved.
The museum has been temporarily closed while investigators complete their work and security measures are reviewed.
One of France’s Leading Art Nouveau Museums
Opened in 2011, the Lalique Museum is dedicated to the work of René Lalique, one of the world’s most celebrated Art Nouveau and Art Deco jewelers and glass artists. Located near the historic Lalique crystal factory in Alsace, the museum houses more than 650 works, including jewelry, glass art and decorative objects.
Following the high-profile jewel theft at the Louvre in Paris in October 2025, French authorities had classified the Lalique Museum as a high-risk cultural site and placed it under increased security monitoring. Despite those precautions, the burglars were able to carry out the theft within minutes before fleeing the scene.
The latest heist has renewed concerns about security at French museums, particularly those housing valuable jewelry and decorative arts collections. Investigators continue to search for the stolen works, which experts say would be difficult to sell through legitimate channels due to their rarity and international recognition.
