A San Antonio man made a special find during a business trip -- a two-carat diamond!

Clay Jarvis found it at the popular Crater of Diamonds State Park in Arkansas.

Jarvis found the eraser-sized diamond on the ground.

He named it Nona J after his grandmother, and now keeps it in a safety deposit box.

It's the fifth diamond this year weighing more than two carats found in the park.
