The Quartz Necklace is one of the Artifacts of Ascendancy, a necklace which gives the wearer the ability to manipulate the destiny of themselves and others. The method of using this power, however, is abstract and remains unknown to any mortals. It was first found by the Pi Tribe after arriving in the mortal realm.
In Dashed Koopa: Barter, the Quartz Necklace is the most major treasure in the game. At the beginning of the game, Dashed is framed with stealing it and is forced to pay back the value of the necklace in five days.
