This barber, who cuts hair inside a carwash, was from Samar and used to be a barber at the Hyatt. We got to talking about his rings. He wears them as pangontra or to protect him from evil spirits and kulam (curses).
One ring was crudely cast from bronze and purchased in Quiapo after he fell victim to a jealous neighbor's ill wishes (it's always about a jealous neighbor, I notice).
Apparently, bronze and gold can keep you protected. This was one of the reasons why old folks in Samar would put gold in their teeth.
