Around 600 years ago, an aristocrat visiting a medieval castle lost an ornate piece of jewelry. But archaeologists recently dredged the unique amethyst set in fire-gilded silver from the muck of the old moat.
"I believe the item was originally part of a brooch or, less likely, a coronet or a crown," Lech Marek, an archaeologist at the University of Wrocław in Poland, told Live Science in an email, "which makes it so unique in a medieval settlement context."
