Jewish betrothal rings from Colmar, Erfurt, Weissenfels (14th c.), and later Italian or Eastern European examples (16th–19th c.) with intricate filigree gold work. Too large and heavy for daily wear, they were used once during the wedding ceremony (the groom placing it on the bride's finger) and afterward kept as a treasured heirloom. In place of a gemstone they include an architectural element, often with a hinged roof that opens to reveal the Hebrew words מזל טוב ("mazal tov," good luck) hidden inside. A nod both to the couple's future home and the Jewish Temple in Jerusalem.
