Jilin Province, China—Last year, Mr. Zhang’s beloved pet dog Hu Zhi (Tiger) suddenly stopped eating and died for reasons unknown. As Mr. Zhang was burying his companion, he noticed a hard lump protruding from the dog’s stomach.
When Mr. Zheng took the dog in for an autopsy to find out the cause of the protrusion, a gallstone about the size of a chicken egg inside was found in his stomach. Mr. Zhang decided to keep the stone as a memento. However, Mr. Zhang was soon informed of a shocking fact: the stone removed from his dog’s stomach has a value of nearly 500,000 Yuan (US$76,487).
Why is this stone worth so much?
