With degrees in Architecture, Urban Studies, and Industrial Design, it was only natural for Colleen Mauer to fall into a field of work that incorporated all three areas of study. Now as a jewelry designer, she constantly observes her surroundings and is subconsciously inspired by architecture, colors, contrasts, and textures in nature. Her design process is organic and unplanned, spontaneous, and surprising. We love that her pieces celebrate effortless angles and that she creates collections that complement any style.
