Julio Jones has a big problem -- he lost a $150,000 diamond earring during a jet ski ride at Lake Lanier this week ... so he's hired a full DIVE TEAM to hunt it down!!
The ATL Falcons wide receiver told WXIA-TV he noticed he lost the earring after he fell off the ski -- but didn't want to just walk away without making a real, solid effort to find it.
The dive team jumped in the water on Tuesday evening -- scouring the 65-foot deep water. So far, no luck.
Jones seems shockingly calm about the whole thing ... probably because he's in the middle of a $71 million contract.
