Having trained extensively in traditional jewellery and silversmithing techniques at top institutions in Germany, Sweden and the UK, they now run successful jewellery businesses. Between them they have many years’ experience teaching and lecturing in the field of jewellery, design and business planning both in the UK and abroad. 

Katrin and Kelvin are passionate about training a new generation of contemporary jewellers to design and make work that is both creatively daring and technically outstanding. 


Katrin Spranger

Katrin Spranger_CHAIN_edited.jpg

Katrin Spranger trained and studied in Germany and holds an MA in Jewelllery from the Konstfack University College of Arts, Cafts and Design in Sweden. Working as a conceptual jewellery artist, she creates stories that comment on consumer culture, environment and science fiction. Focusing on resources that might become depleted in the future, she explores natural materials including crude oil, water and honey to develop wearable but also time-based and interactive jewellery. Her hybrid practice touches several disciplines like fashion, food, photography, performance and installations. 

Katrin has taught widely both in London and Germany. She has won numerous awards and has exhibited widely throughout Europe and North America.

Kelvin J. Birk studied jewellery making in Germany and holds an MA with distinction in Silversmithing, Jewellery and Allied Arts from the Sir John Cass Faculty of Art. He has exhibited at major exhibitions both in the UK and abroad.

He creates one-off bespoke pieces in silver, gold and crushed gemstones. Within his work, he consciously disregards what is traditionally considered precious, revelling in a lack of control, allowing chaos to take over and the nature of the precious materials to dictate the outcome of the pieces.  

Kelvin has taught extensively, running jewellery master classes and workshops internationally. He has tutored at the Kensington & Chelsea College, London, and was visiting lecturer on the Fashion MA at the University of Westminster, London and at the Kunstschule Liechtenstein. He is currently a part-time lecturer on the BA Jewellery & Silversmithing course at Metropolitan University London.
