The clip comes from Hitman: Blood Money, the 2006 stealth game in the Hitman series, where Mark Purayah II is one of the rival assassins Agent 47 encounters. His single word line naming diamonds was isolated by players and shared on soundboards because it works completely out of context. Unlike longer Hitman quotes, this one needs no setup, so it travelled into gaming edits and reaction videos as a shorthand for greed, loot and sudden wealth. Its continued use comes from that portability and the character's unusually serious tone.
