David Spohr, 55, had spent a fruitless morning searching through a cow field in Blandford, Dorset, with his metal detector and eventually decided to give up and take a lunchbreak. But as he was tucking into his sarnies, he heard its alarm sound.
At first, he believed it was just a sardine can that was causing the noise but as he dug deeper, David discovered a gold necklace.
The 3,500-year-old solid gold artifact is thought to be a lunula – a crescent worn by tribal leaders. The item is thought to be worth up to £20,000 and is only the fourth Lunula to be discovered in mainland Britain.
The money will be split between David, from Poole, and the owner of the land it was found on and is likely to end up in a museum.
Engineer David said: "I was amazed. You never expect to find a lump of gold. It's something you dream of, the find of a lifetime."
