By Karin

My name is Karin Springer, goldsmith in heart and soul, with 45 years of experience in creating and reparing jewellery. Since 1990 I work in my own studio 'Het Hamertje' in Rotterdam.
In 2007, the idea came up to combine my two passions, forging jewellery and cycling, in Sportsieraad,
a collection, of custom designed and handmade jewellery inspired by cycling. A range of unique designs of several other sports followed shortly after.
In addition to continuous expansion of the sports jewellery collection I also like to work on assignment, like creating wedding- and friendship rings. But whether you choose custom-made jewellery or a collection piece, it always has personality and quality.
In short: Made by Karin!
