The Chinese call them yemengzhu or legendary luminous pearls. These are not true pearls but spheres of a rare kind of glow-in-the-dark fluorite, a mineral which is sometimes used in jewelry making. The Chinese believe good luck and fortune will come to those who touch these legendary luminous pearls.
This record breaking pearl, currently being exhibited in Hainan province, weighs 6 tonnes and is about 1.6m high. It took 3 years to grind the specimen into a large round ball. It has been valued at 2.2 billion yuan or $331 million. Any takers?
