"The blue stone from "Bergslagen" in Sweden is unique. It emerges from a materia you only find in medieval foundry ruins. The colour shades are determined by remainders of the old rock. Each stone is cut and polished by hand. That's why the form of each stone differs from the rest and the reason why this jewel of yours is quite unique."
