As a company steeped in tradition, J. Köhle has its roots in Pforzheim, Germany, where the enterprise was established in 1872. The company has been under the management of the Köhle Family since 1919.

 

In 1926 we began to focus our efforts on developing fascinating solutions in the form premium quality clasps.

 

Today, the many years of experience we have accrued paired with our technical and professional know-how are all evident in the exacting quality of our clasps and jewellery models. As the years passed, we have generated a one-of-kind JKa portfolio – your amazing to the world of jewellery.

 

At this time, the team at the helm of our company consists of members of the 3rd generation of the Köhle Family: Karina and Norbert Ratzlaff as well as Margit Kühnel are the managing directors of our successful enterprise.

 

Margit Kühnel is our trend scout. In numerous conversations with customers on location at domestic and international tradeshows she determines what they are and implements them in our corporate projects. As a result, our design language is distinct and clear.

Production

 

Jewellery and Clasps from a Single Source

 

Even in the 21st century, ideas for jewellery pieces and related technical solutions are still developed in our employees’ heads. They use ultra modern CAD technology to implement our ideas and come up with a variety of options:

 

• Different sizes

• Mirrored designs

• Different layer thicknesses

• Diamond and coloured stone alternatives

 

Thanks to all of these different facets and designs, we are in a position to offer a fascinating JKa jewellery model and clasp portfolio for our clientele to choose from.

 

Our data and designs, which are generated with the assistance of CAD systems, are transferred to our in-house rapid prototyping and CNC systems. Subsequently, we make the appropriate tools and ultimately manufacture the jewellery models and clasps.

 

Proprietary, ultramodern cast moulding processes enable us to draft small lot sizes or even free form pieces. Our own presses, embossing, stamping tools and devices, support the production of micro-precision larger numbers or functional parts.
