I also enjoyed this film.
[TREECE (Robert Shaw) discusses the potential value of a piece of jewelry found during a treasure dive with DAVID (Nick Nolte) and GAIL (Jacqueline Bisset).]
TREECE: The ocean’s not a jewelry store. You don’t get no receipts. You’ve got to prove that that’s authentic.
DAVID: (Exasperated). Well, anybody can see it’s authentic.
TREECE: You don’t understand me, boy. There’s a lot of counterfeit on the market today. I mean it’s real gold, it’s real gems, but it’s false. Now you have to establish a provenance. You got to do that first. You’ve got to find a proof that it’s real. Now if we could find in here (referring to the ship manifests) a verifying record, a description of any piece down there. That makes it all worth a bloody fortune.
