The item is expected to fetch between 30,000 and 40,000 $35,500 and $47,300 when it goes on auction later this month.
He said there will probably never be another one like it during an interview with CNN. Back then, each ring was individual and unique, not mass produced like today. It is stunning. In 2019 the metal detecting board took up metal detecting again. During the second day of a field search, he had almost given up when he got a signal on his metal detector by a footpath.
The culprit looked like a sweet wrapper at first, but Board soon realized that it was a gold ring.
When he dug it up all covered in mud, Board said he thought it was just scrap metal and popped it into his pocket.
It was when I got home and washed it off that we realized it was a lot better than we thought, he explained.
Nigel Mills, a consultant in coins and antiquities at Noonans, said the ring is in perfect condition. The jewelery has a golden hoop of two entwined bands to symbolize the marital union and an inverted diamond set into it.
Inside the band is a medieval French inscription that reads, Ieo vos tien foi tenes le moy, translating as I hold your faith, hold mine, according to the auction house.
The Noonans' experts believe that Joan Brook's wedding ring was given to her by her husband, Thomas Brook, due to the location of the find and the quality of the ring.
Their marriage in 1388 brought great wealth to the Brook family, the release said, because Joan was the widow of Robert Cheddar, a wealthy cloth merchant and twice mayor of Bristol, a city in western England.
The item, known as The Lady Brook MedievalBrook Medieval Diamond Ring, will be auctioned on November 29.
The board goes out three times a week, weather permitting, in hopes of uncovering another great relic among the musket balls and King George I coins.
He said that it would be amazing if I did. He added that you never know what the next signal is going to bring. The discovery adds to a list of incredible finds made by detectorists in the UK.
