925 Silver Temple Rings from online Medieval Poland (full set). Historical Reenactment

Temple rings are the most characteristic part of Slavic medieval dress. They are so called because they were worn on the headband, near the temples of a woman or a girl. Most were made of base metals such as copper alloys or iron, though silver and even gold were occasionally used.
