What is my precious?

"My Precious" is a term often used by the character Gollum in J.R.R. Tolkien's "The Lord of the Rings" series to refer to the One Ring, which he has become obsessed with and considers to be his most treasured possession. The ring is a powerful and malevolent object that holds great influence over its owner, corrupting their mind and driving them to evil acts. Gollum's desperate desire to possess and protect the ring ultimately leads to his downfall. The phrase "my precious" has since become a popular cultural reference for something that is highly valued or cherished by an individual.
