Handmade silver jewelry with a Swedish stone named Bergslagssten.
The stone is a residual product from Swedish iron production over three hundred years ago. Production took place in small coal-fired ovens, where the ore was melted to a liquid mass.
The stone is formed when the furnace has a sufficiently high temperature to glaze the ore. The rock is the slag that is formed during metal smelting. The slag floats at the top of the melt and is discharged from the blast furnace before the metal. The slag is available in all possible colors and textures. What distinguishes Berglaggsten is precisely the blue color and the texture.
