About Brännhult

North of Älmhult in southern Småland province lies Brännhult, a black diabase quarry since the 1950s. Operations closed down in the 1970s but gathered momentum again in the late 1990s, and today Swedish Black Brännhult is our best-selling diabase. It can be found for example in the fountains at the One World Trade Center in New York, and clads the facade of the Swedish embassy in Berlin. In Sweden, diabase from Brännhult has been used to create beautiful floors, stairs and benches in Swedbank’s head office in Stockholm, as well as artist Pål Svensson’s sculpture Utblick/Insikt outside Malmö Central Station, to name just two examples.

The diabase from Brännhult also has a very low coefficient of expansion in temperature fluctuations, which makes it ideal for measuring plates, which are used in the manufacture of high-precision products.
