Alsengemmer refers to diminutive glass setting stones found in both religious and secular environments. These are thought to have served as amulets for pilgrims. The term 'Alsengemmer' originates from the Danish island of Als - the location where these artifacts were first discovered. An alsengem dating back to the 13th-14th centuries, featuring three carved figures, was unearthed in Kalmar by archaeologists.
