“Perfection occurs when passion meets experience”

The world of Leo Wittwer
Leo Wittwer epitomises the highest perfection in the jewellery industry, where standards in quality are very high. We only use the best materials during manufacturing and everything is made in our workshop under the same roof.

The concept

After some manual sketches have been made on the new piece of jewellery, the first draft is sketched by hand.

The model

The model of the designed piece of jewellery is handcrafted in gold


To increase the melting ability of the gold, the surface of the model is annealed


The "cast skin", which arises during casting and annealing, is removed by hand


Setting means that the diamond is firmly anchored in the metal


Individual components of the piece of jewellery are assembled


The closing is the creation of a closure, which is needed to open and close a necklace or bracelet

Quality control

Before a piece of jewellery can leave Leo Wittwer, it is checked by specialists for various quality features

More than a quality seal, it is a promise

"Made in Germany" bears the highest recognition and appreciation worldwide. The term is regarded worldwide as a seal of quality, durability and reliability. From its design to the final production, all steps must be undertaken in Germany!
