About the stone
Getting to know Älvdalen Quartzite
A 1.4 billion year old quartzite quarried at Mångsbodarna in northern Dalarna. The veining runs in changing angles across each slab, so no two pieces read the same, and the colour moves from pink-red to a deep red-brown. Quartzite ranks among the hardest natural stones in the world, and Älvdalen quartzite among the hardest in Sweden; it clads Uppsala City Hall and the city library in Dortmund.
Where to use it
As a hard silicate stone, Älvdalen Quartzite is supplied for facades, external paving, paving slabs, setts, block steps, walls, interior flooring and interiors. For external surfaces we recommend a flamed, bush-hammered or blasted finish, which keeps its grip when wet. Thickness and format for paving depend on traffic load and bedding; we size them with your engineer against EN 1341 to EN 1343.
Finishes
- honed: smooth and matt, shows the pattern, for interior floors
- flamed: rough and slip resistant, for external paving and steps
- natural cleft: lively with good grip, for walls and landscaping
- bush-hammered: evenly textured, the classic finish for squares and plinths
- polished: deepens the colour, for interiors and facade details
Origin and geology
Dalarna in central Sweden is an old stone province, home to the quartzite of Älvdalen in the north and to sandstone quarried around Orsa since the sixteenth century.
Granite, quartzite, gneiss and diabase are silicate rocks: hard, dense and unaffected by acids. They are the stones for facades, squares, setts and steps, wherever stone has to take frost, de-icing salt and traffic.
Supply and documentation

Questions
Is Älvdalen quartzite a granite?
No. It is a quartzite, a metamorphosed sandstone. In construction it is classed as a silicate stone and behaves much like granite.
Can Älvdalen Quartzite be used outdoors?
Yes. It is used for facades, external paving, paving slabs. Choose a flamed, bush-hammered or split finish outside so the surface stays slip resistant in the wet.
Which finishes are available for Älvdalen Quartzite?
Available: honed, flamed, natural cleft, bush-hammered, polished. Other finishes on request.
