A 10-year-old Israeli boy out on a school trip in Jerusalem unearthed a cross medallion between 100 and 200 years old. He found it in the city’s southwestern Ein Karem neighborhood, a venue venerated by Christians as the birthplace of John the Baptist. It was crafted using a micro-mosaic technique.
