A great success was celebrated by the Long Night of Gemstones in 2022 and 2023. We invite you to experience the uniqueness and expertise of Idar-Oberstein during the 3rd Long Night of Gemstones.

On Saturday, April 12, 2025, selected institutions and locations in the jewelry and gemstone industry of Idar-Oberstein will open their doors free of charge to visitors from 7:00 PM to midnight in a pleasant evening atmosphere. At the various stations, there will not only be relevant information but also an attractive supporting program with readings, guided tours, musical performances, and informative contributions.

The Long Night of Gemstones will be officially opened at 6:45 PM by the German Gemstone Queen Vivian Heidrich, Dr. Heide Rezepa-Zabel, and Julian Schmitz-Avila. The venue will be announced later.

The Idar-Oberstein Trade Fair is organizing bus shuttles, allowing visitors to independently decide which and, above all, how many stations they want to visit that evening. Alternatively, the stations can be reached by private car or on foot. There are capacity limits for the guided tours. Therefore, online pre-registration through the Idar-Oberstein Trade Fair is required for those interested. The possibility for pre-registration and details about the participating institutions will be published here about two months before the event.
