Swedish green marble
Swedish green marble, or simply Swedish green, is a marble from quarries in Kolmården, in the north-eastern part of the province of Östergötland in Sweden. It is fine-grained, with a variable green colour and attractive veining, due to serpentines in the stone. It is considered one of the hardest marbles in the world. Swedish green has been used extensively in buildings and monuments in Sweden and abroad. The main desk in the General Assembly building of the United Nations features the presiding officials rostrum constructed from green marble, with a matching wall behind it. Swedish
