While walking his dog with his mom, a 12-year-old boy in the U.K. made an unexpected discovery in a field — not a stick for his dog or an interesting rock, but a first-century gold bracelet from Roman Britain.

Unlike most other jewelry from the Roman era, the lustrous bracelet probably wasn’t worn by a woman, researchers later surmised. Instead, it likely belonged to a man who had received the accessory as a military honor, likely an “award for bravery,” according to a statement from the local Chichester District Council.

The cuff bracelet has been described as “exceptional” and “relatively rare in Roman Britain,” especially because it’s crafted from gold, according to the statement.

A newly announced analysis of the bracelet revealed that it was made from sheet gold with raised moldings, and it dates to the first century A.D., not too long after Roman emperor Claudius invaded Britain in A.D. 43.
