The world's largest luminous crystal

The world's largest luminous crystal has been on display in Xi'an, capital of northwestern China's Shaanxi province, during the National Day holiday.

The translucent crystal has a diameter of 1.6 meters and weighs 6.2 tons. It emits green and white light at night, which makes it look like the moon in the nighttime sky.

The crystal has attracted many visitors' attention and become a hit of the Antiques and Art Exhibition in the ancient city.
