Claus Bjerring's career began with an apprenticeship in the workshop of Danish silversmith Georg Jensen. During this time of study, Bjerring learned how to work with precious metals and was taught to adhere to tradition, including the custom of removing every tool mark from his material in order to give it a clean surface. With recent pieces, Bjerring has worked more freely with his material, playing up the metal's inner qualities and allowing his work to develop more naturally. Exploring the plastic properties of gold, he now allows to take on an unfinished appearance, with marks from tools and technical procedures clearly visible as dynamic design elements.

In 2007, Bjerring was honored with a retrospective in the City of Copenhagen. More than 200 of his pieces were brought together in a singel exhibit that spanned three decades of work. His jewelry is in collections of Victoria and Albert Museum in London and the Museum of Art and Crafts in Copenhagen
