1.p154

If a monk pick up with his own hand a jewel, or the setting of a jewel, or if he cause some one to pick it up for him, except within the precincts of the monks garden, or in a place of entertainment (i.e., a lodging-house), it is pācittiya. He may only pick up such articles in the places named, with a view to their restoration.
