Kolmård-marble with its unique, green color and beautiful graining, makes it together with the superior wear strength, a attractive material. This beautiful stone is mined in Kolmarden, Östergötland, and is known both for its beauty and its quality over almost the entire world. Architects and builders have for centuries used this quality marble for both art and ornaments to the construction industry. Finishes may vary from the polished to the ground, blasted and carved.
For outdoor use it is recommended a rougher surface finish. Kolmård-marble has been used in large and important buildings, even far beyond Sweden's borders, and has been mined since the late 1600s. Mining ceased completely in the early 1970s, and it would take 20 years before Borghamns Stenförädling AB took up mining again. A new era in Kolmård-marble history has now begun. The green-veined marble is used in an increasing number of new projects.
