They are significantly larger than [[Blue Diamond]]s and [[Red Diamond (Luigi's Mansion)|Red Diamond]]s. Each Gold Diamond is worth 20,000,000G, which is the highest value of any collectible in the game. One of the Gold Diamonds is obtained after Luigi waters a plant three times in the [[Boneyard]], specifically if he does so before the battle with [[Bogmire]], after the battle, and lastly after defeating [[Boolossus]] for the flower to bloom, revealing the diamond and several other treasures. The only other Gold Diamond is obtained after Luigi captures all [[List of Boos in Luigi's Mansion|50 Boos]]. If Luigi captures the final Boo and the player saves the game, the Gold Diamond's location is saved as being on the ground, so if the player does not save the game again, the Gold Diamond is lost permanently if either the game is turned off or the player receives a [[Game Over]].
