25x20mm Italian Real Shell Cameo of St Peters Basilica unmounted loose Genuine Hand Carved C303

I don't really know the age on this. Not new. I believe this is Saint Peter’s Basilica, located in the Vatican City, and is considered one of the Catholic Church’s holiest sites and foremost pilgrimage destinations, which marks the burial site of Saint Peter, Christ’s foremost apostle and the first ever pope. Condition of the shell seems to be good. I do not see any splits or chips. Seems solid.
