About

Our journey to create the most unique, ethically grown and Swiss Made diamonds began over 5 generations ago. 

The Ziemer family with five generations of diamond history looked to technology to better the diamond industry and increase quality from their home town in Biel/Bienne Switzerland. Together with Dr. Robert Chodelka considered a pioneer in gemstone quality HPHT lab grown diamond technology,  they have together steadily pushed the envelope of Swiss diamond technologies.

As a scientist Dr. Chodelka has spent over two decades perfecting the Bienne diamond formulas to deliver the widest range of color, cut and size of unique carbon based diamonds.

Bienne diamonds are grown by Dr. Chodelka and his team in Port Switzerland a municipality of Biel/Bienne. Combining craftsmanship, engineering, and scientific know-how the team at Bienne grown diamonds that are atomically identical to naturally occuring diamonds. Every diamond grown by Bienne is unique to the carbon source provided by our customers making each and every diamond a symbol of true provenance and luxury.
