The width and artistic complexity of Sigurd Persson's artistry is almost overwhelming and makes him one of the greatest goldsmith and artists of the 20th century. After a long education in both Sweden and Germany he opened his own studio 1962 on Högbersgatan in Stockholm, but already in 1960 he gained international recognition with the exhibition "77 rings" at NK in Stockholm.
