Continuity mistake: When Joan's bus crashes, the film editing becomes chaotic: suitcases on the roof fall in one shot, then remain in place on the other; the stuff on the ground keeps appearing/disappearing randomly, and Joan's blue suitcase swaps from laying horizontally to diagonally.
Sacha Continuity mistake: After Joan's bus crashes, the parrot on the jeep keeps changing positions in every single shot.

Sacha Visible crew/equipment: During the opening credits sequence, where Kathleen Turner is at home with her cat, she opens a glass cabinet to take out a bottle of alcohol. Throughout this shot we can see a reflection of the camera man (wearing a red t-shirt) directly in front of her face.
Factual error: None of the "Colombians" speaks with a Colombian accent or uses Colombian slang.
Answer: Any emerald over 1 carat in that beautiful cut and condition would probably go for over 250 million. Real emeralds over 5 carats are rare and the price goes up exponentially after 2 or 3 carats. 305,000 per carat after 5. So yeah that one was probably like 800 or more carats.
