The Ruby Ring was one of the gifts given to Graham when he gave Grandma some Chicken Soup. It was a gold ring with an enormous red ruby. The initials 'C.D' were engraved inside the gold band. It once belonged to Count Dracula. It is unknown how it got into Grandma's possession. While wearing it with the Black Cloak graham was able to fool the Ghoul Ferryman into letting him cross over the Poisoned Lake over to the island where Castle Dracula was located. They also fooled the Ghosts into letting Graham into the castle.
