Blood Rubies, also known as Rich Stones (リッチストン Ricchi Suton) in the Japanese version, are a type of valuable ruby that are located in the bottom of the Land of Gurumes. Those rubies are cursed and deteriorate everything around them.
King Gurumes paid Bongo and Pasta in these in exchange for gathering the Dragon Balls for him. When Penny made a wish to Shenron to restore the land, all of the blood rubies were removed from the ground which seemed to have been behind all of the corruption.
