エイジャの赤石 (えいじゃのせきせき)

Distinctive red gem from Part 2 of [[Jojo no Kimyou na Bouken]].  Sought after by the Pillar Men, as it is key in their quest for perfection. Often seen as a [[necklace]] on [[Lisa Lisa]].

Given Hirohiko Araki's fondness for musical references, it is not unlikely that the object might be named for either the album [i]Aja[/i], Steely Dan's sixth, released on 23 September 1977, and the song "Aja" on said album.
