Colmar Treasure

Jewish ceremonial wedding ring, from the Colmar Treasure, ca. 1300– before 1348.
Hidden for 500 Years, the Colmar Treasure Recalls the Persecution of Medieval Jewish People
The treasure is believed to have belonged to a family caught up in 14th-century violence that destroyed the thriving Jewish community of Colmar in Alsace. That anything at all survives is a miracle.
