About Mojo Design
Mojo Design is a goldsmith workshop in Winterthur that crafts individual wedding rings, engagement rings, and unique jewelry by hand. The pieces are mostly forged in the workshop itself; some come from fellow goldsmith friends. The largest share of the gold processed comes from fairtrade-certified mines in Peru; the workshop is itself fairtrade and fairmined certified and also works with recycling gold and precious scrap from its own purchasing. Services include individual jewelry fabrication, jewelry remaking including setting existing precious stones, engraving of jewelry and watches, repairs, and appraisals of jewelry and precious stones. In addition to manufacturing, the workshop offers workshops where customers can forge wedding rings themselves. As a training establishment, Mojo Design trains future goldsmith and is committed to topics such as circular economy, climate protection, and transparent material sourcing.
