We at Maren Jewellery exclusively use recycled gold, so no new gold needs to be mined for our jewelry pieces. The recycled gold is sourced from our RJC certified refinery. C.Hafner, which recovers gold from old jewelry, electronics, or dental gold and fuses it into a new, recycled gold alloy. The materials for this come 90% from Germany and 10% from neighboring EU countries. Also our Gießerei Kauselmann works exclusively with recycled gold, thus preventing new gold mining. Therefore, our Mini Sphere ball earrings are of course made only from Urban Mining gold.
