Trivia: The film was written by Diane Thomas. Thomas was a struggling waitress and actress, and had been working odd jobs to make ends meet when she wrote the script. While there is some dispute over how it happened, eventually the script made its way to actor Michael Douglas, who championed Thomas and helped get the movie made. The script was so well-liked, she ended up getting numerous offers, and at one point was even attached to help write one of the "Indiana Jones" sequels. Sadly, she was killed in a car accident only a year after this movie's release, and it remains the only film she was credited for writing.
Question: What is it likely that the stone (an emerald, I gather) was worth in 1984 US dollars?
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.
