Who is the true owner of 380kg US$400mil emerald

LOS ANGELES: A California man is trying to prove he owns an 840-pound (380-kilogram) emerald dug up in the Brazilian jungle, but a group of businessmen say he's nothing more than a tourist who had his picture taken with it.

It's up to a Los Angeles judge to determine if Anthony Thomas really owns the $400 million Bahia Emerald, which has spent the past 10 years on a mysterious journey across the U.S.
