The neck rings, which are 2,500 years old, were discovered in a grave during an archaeological survey in Marby, writes Arkeologerna, a department within the Swedish National Museums (SHM), on its website.
In recent weeks, archaeologists have been investigating parts of an ancient site east of Norrköping that includes graves, rock carvings and settlement remains from the Late Bronze Age. This is because new housing is to be built in the area.
The neck rings, known as wendel rings, appeared during the Late Bronze Age and are unusual finds because they are made of cast bronze.
"At Häradshammar in Östergötland, not far from our find, there is a deposit of two wendel rings found in a bog. But the fact that two neck rings were placed together in a stone setting with burials is unusual, perhaps unique," says Alf Ericsson.
The rings are believed to have been laid down as offerings. The neck rings were a status symbol and were most often worn by women.
In one of the graves, cremated human bones were also discovered, partly in an urn and partly in smaller pits in the ground.
