The Alice and Louis Koch Collection of finger rings was originally collated by a jeweller from Frankfurt am Main, once described as the German ‘Cartier and Fabergé’. By 1909 the collection comprised 1,722 rings from Antiquity to 1900. René Lalique, a contemporary of the time, was included, undoubtedly as a moderniser of the ring form. In the past twenty-five years the fourth generation of the family continued where Louis Koch and his wife Alice left off and expanded the collection to include rings from the twentieth and twenty-first century. This publication will present the complete collection of contemporary rings, today kept in the Swiss National Museum, Zurich. Nearly 600 rings by artist jewellers from around the world document how these miniature works of art have become modern sculptures showcasing new materials and techniques, daring designs and current themes.
