A group of amateur archaeologists unearthed the largest ancient Viking gold treasure trove in Denmark.

According to Tech Times , a group of archaeologists named “Team Rainbow Power” found 7 Viking-era necklaces in a field in the city of Vejen in Jutland.

The ancient necklaces include six gold and one silver necklaces, estimated to have been created in the year 900, according to the National Museum of Denmark. With a total weight of about 900 g, this is the largest Viking gold treasure ever discovered in this country.

Marie Aagaard Larsen, one of the archaeologists, said she found the first necklace after searching the field for about 10 minutes. Next, Larsen, along with her husband Christian Nedergaard Dreioee and close friend Noergaard Pedersen, discovered many more necklaces.

After collecting the first three necklaces, they asked expert Lars Grundvad at the Sønderskov Museum for help. Grundvad said two of the seven necklaces were made in the Jelling style associated with the aristocracy of Viking society.

According to Peter Pentz, a Viking expert at the National Museum of Denmark, the necklaces could have been gifts from the Viking king to loyal servants or allies. They may have been buried during a ritual or buried by someone for safekeeping purposes.
