Our History
Our development over the last 120 years
A beginning full of passion
The story of Gerhard Hahn begins in 1901, when Otto Hahn laid the foundation for the company in Paris. With a deep passion for gemstones and an unwavering pursuit of quality, he created the basis for a brand that still stands for excellence and trust today.
A new beginning
Between 1930 and 1933, Gerhard Hahn learned the craft of gemstone processing and international trade under the guidance of his father Otto in Paris. In 1934, Gerhard Hahn took over the management of the family business and moved the company headquarters to Berlin. With a clear focus on quality and a growing vision, he began to lead the company into new markets.
Miachael Hahn - A Generational Change
In 1978, Michael Hahn followed in his father's footsteps and took over the management of the company. With fresh ideas and a deep-rooted passion for gemstones, he continued the family tradition and strengthened Gerhard Hahn's position as a reliable partner for high-quality gemstones.
Alexandre Hahn – A New Era
Since 2014, Alexandre Hahn has led the company with a focus on innovation, such as the introduction of blockchain technology in 2023, which redefines transparency. During the pandemic in 2020, the range was expanded to include indigo blue tourmalines from Namibia, followed in 2023 by rare yellow diamonds from the same region. In the same year, Gerhard Hahn was awarded the Inhorgenta Award for "Gemstone of the Year" - proof of the outstanding quality and exclusivity of the gemstones.
