Stone (Luigi's Mansion)

Stones, also called Jewels, are valuable collectibles found in the game Luigi's Mansion. There are three different colors of Stones: Blue (500,000G each), Green (800,000G), and Red (1,000,000G). Ten of each color can be found in the Mansion, totaling 23,000,000G. To find them all, Luigi has to water all the plants he can find, examine a variety of objects such as buckets, gutters and gold chandeliers, catch Speedy Spirits, and light up all the rooms in the mansion except for the third and Basement floor hallways.
