A colossal emerald valued at almost $400 million is under lock and key in Los Angeles County while detectives try to figure out who owns it, the Wall Street Journal reports. Police managed to track down the 840-pound Bahia emerald after it was reported stolen last fall, but they also uncovered a web of competing claims for its ownership.
After two billion years in the ground, the emerald was unearthed by a Brazilian miner in 2001. It was later shipped to the US by a gem trader and spent weeks submerged in a New Orleans warehouse after Hurricane Katrina before being sent to California. Starting next week, a civil court will hear claims from at least five parties who say the gem belongs to them.
