Crown (King Boo)

King Boo's Crown is the final piece of jewelry Luigi collects before he saves Mario in Luigi's Mansion. In Luigi's Mansion, the crown holds a red diamond at the top. Officially, King Boo's crown also counts as a Red Diamond. The crown is worth the same amount as a single coin.

The crown has changed in the later Mario games it has appeared in. It is nowadays shown as a golden crown encrusted with jewels, similar to Princess Peach's crown. In the upcoming game, Luigi's Mansion: Dark Moon, however, King Boo appears to sport the crown's initial appearance.
