A natural, gently wavy and highly light-reflective surface in a deep grey tone.

The slate is extracted from a large deposit in the bedrock between Rönnöfors and Finnsäter, near the Norwegian-Swedish border. The natural surface is created when the stone block is split by hand along natural layering without further treatment. All subsequent processing of format and thickness takes place locally at the quarry, ensuring consistent quality and a minimal climate footprint.

Place of origin Offerdal in Krokom municipality, Sweden Petrography Quartzite slate
