[You can get a discount here with Oslo Explore] Create your very own ring from scratch! In Grünerløkka, you’ll find an intimate and creative jewelry workshop. Over four hours, you’ll learn to shape a wax ring, cast it in sand using molten tin, and then sand and polish it until it shines. The class and space are warm and social, with good music and room for around eight participants. The process is surprisingly meditative – and you’ll leave with a personal piece of jewelry the same day, beautifully packaged in a box.
