- "The Eye of Despair! I have the entire gem at last!"
- ―John Stryke
The Eye of Despair was a large, red gem that was of great wealth. It was hidden inside a treasure chest in the Grotto of Despair.
John Stryke owned a piece of the ruby, which hid his deformed appereance. Later, he used the crew of the Black Pearl to lead him to the rest of the ruby. A swordfight ensued between Jack Sparrow and Stryke, which eventually turned out to favor Sparrow, with Stryke stuck in a treasure chest. During the duel, Stryke dropped the Eye into a pit.
