An NFL star's diamond earring valued at more than $100,000 is now presumed lost on the murky bottom of a Georgia lake.

WXIA-TV reported Tuesday that Atlanta Falcons star wide receiver Julio Jones lost it when he hit a boat wake and took a spill while jet skiing in Lake Lanier 80 kilometres outside Atlanta.

He resurfaced but his pricey earring didn't.

SCUBA divers have been searching the lake bottom, hoping to capture a flashlight's reflection off the jewelry amid old trees that have been submerged since the man-made lake's creation in the 1950s.

So far, no luck.

But if Twitter is any indication, there are a lot of people willing to look for it.
