Stripa hematite is a type of banded hematite (bloodstone) from the Stripa mine in Bergslagen. It is known for its striped structure with quartz bands and a dark hue, which gave the mine and the town their name—“stripa” refers to the striped ore bodies. The hematite has been mined since the 15th century in one of Bergslagen’s oldest mines, featuring striped, non-magnetic ore that differed from magnetite-rich deposits.

Bergslagssten, also known as Bergslag slag or slag stone, is a byproduct of iron production in blast furnaces and smelting houses. It was formed when iron ore was smelted with charcoal, and its blue hue arises from slow cooling, which gives it a glass-like, iridescent structure. Cobalt and chromium are responsible for the blue hues.

Our rich cultural heritage from the Vendel and Viking periods has inspired many so-called Viking jewelry pieces. The pendants with rock crystals are crafted in silver, just as the older originals were.
