A carved piece of marble

 is a refined crafting material that is used to make the highest tier of marble-work. It's one of the few items that require faith in order to craft, making them relatively precious. They are also complex, meaning they have a variety of quality levels.

Regarding these varying qualities, carvings can be utilized within the church, or bought and sold from the vendor Cory, while the  carvings are used in a variety of applications regarding the Graveyard. The carvings are only employed during a quest for the Bishop; however, with the Game of Crones DLC, they are also used to craft higher-tier marble headstone sculptures.
