The Red Stone of Asia

The Red Stone of Asia is a artifact from the second arc of JoJo's Bizarre Adventure. It is a flawless gemstone, capable of refracting the light that goes through it a thousand times, concentrating it into a single point to generate a powerful light beam. This rare gemstone was sought by Cars, leader of the Pillar Men (a powerful race of ancient beings), who needed it to use in conjunction with the Stone Mask in order to overcome his sunlight weakness and turn him into the ultimate lifeform. The stone was kept with the Hamon clan, the only ones who could fight them, but was not destroyed due to a prophecy that told destroying it would make fighting the Pillar Men even harder.
