UNDATED (CNN) -- It's like something out of an adventure novel, but the difference is this story is true!
A young mountaineer stumbled upon a hoard of mysterious jewels worth as much as $330,000.
The climber, who wants to remain anonymous, came across the stash inside a metal box on top of a glacier in France.
French media say the stones were rubies, sapphires and emeralds. Authorities say they might be from the 1950 crash of an air India flight during a storm.
If no owner is found, the mountaineer could be allowed to keep a portion of the jewels' value.
