Ruby as a Light Source
In ancient Asia, the ruby was called the glowing or lamp stone because of its luminous quality. It was believed that an Emperor of China used a ruby to light his bedroom. In Greek mythology, Heraclea's kindness to a female stork was rewarded with a ruby so bright she was able to light her bedroom with it. One Burmese king is said to have owned so many rubies that when he took them outside to absorb the moonlight, the rubies lit up the night sky above the city. Interestingly, today rubies are used in lasers.
