Gold Diamond



Gold Diamonds are the most valuable treasures in Luigi's Mansion, worth 20,000,000G each. There are two in the game: Luigi must water a plant three times in the Boneyard (where Spooky resides): once when he first sees it, once after defeating Bogmire, and once after defeating Boolossus to make the now-flower bloom, revealing the diamond. The other can be found if Luigi captures all 50 Boos besides King Boo; the last Boo will drop the treasure right in front of him. If Luigi wants a good mansion to live in, he should collect both Gold Diamonds.

They are significantly larger than Blue Diamonds and Red Diamonds.
