The carat indicates the amount of gold in the material the ring is made of. One carat indicates that the gold weight is 1/24 of the weight of the alloy. Thus, in 18 carat jewellery, the amount of pure gold is 18/24 (75 %).
The gold used at Guldbolaget
At Guldbolaget we use recycled gold, i.e. gold that has been revised. The value of gold is the reason why jewellery not being used, is sold and reused. The advantage of working with recycled gold is that the environmental impact is minimal when gold moves around in a cycle. The quality of the gold is not affected by the re-utilization, it is the exact same as with new gold.
At Guldbolaget we make every metal alloys (gold fusions) ourselves, in our own workshop. And we ourselves make all further processing into finished rings. The fact that we own the whole refinement process gives us the least environmental impact possible. The fine gold, which we use for our metal alloys, comes solely from different eco-certified providers who recycle and purify gold. Thus, we use the “gold from peoples’ drawers” only after the gold has been purified by an environmentally certified company.
The gold content in our alloys is continuously controlled by SP Technical Research Institute of Sweden, which ensures that we meet all requirements set according to gold content. A ring from Guldbolaget is a ring manufactured under the most optimum environmental control possible.
