Small round glass-fronted silver reliquary theca housing second-class ex capsa (from the sarcophagus) relics of Saint Maria Domenica Mazzarello. The relic is affixed to a red silk background, surrounded by gilt paperolle ornamentation, and identified on a typeset cedula label as S. Geminiani Ep. Modena C. (Ex capsa / S. M. Mazzarello). On the back, under a protective cap, the theca is secured by a seal of red wax with a partially preserved imprint of a coat of arms of the Silesian Order.
