Armed with his metal detector, a retired fishmonger from Derbyshire, England uncovered buried treasure in the grounds of the Peak District's Castern Hall in February 2018. Speaking about his find, the unnamed 64-year-old said: "I got a strong signal and started digging down but hit a large, round, flat stone. When I lifted it up, I found the mammoth gemstone".
What he’d unearthed was a 400-year-old ring (pictured). Set with a purple-blue chalcedony stone, the ring is carved with the initials "GL" and depicts three candles. Dating back to around 1600-1650, family records suggest the first owner of the ring could possibly be Geoffrey Lowe, the former squire of St Mary’s Church in Denby, who died in 1637. The ring has been valued at between £25,000 ($31.7k) to £35,000 ($44.4k).
