Kansas City, Mo. ? A national jewelry store chain is looking for a “nice way” to thank a Midwest Airlines employee who found a cargo bag with $266,000 worth of jewelry inside and took it to police.

Ramp agent Robert Lewis said he saw the Brinks cargo bag in the middle of the street as he left Kansas City International Airport for home Monday night.

Inside, Lewis found a 40-pound box marked “Helzberg Diamonds” and containing wedding rings, bands, sets and loose stones.

“I saw all the rings,” Lewis told Kansas City television station KMBC, “engagement rings, wedding rings, just unattached stone, diamonds, everything.”

He said he briefly thought about keeping the bag, then decided to turn it over to police.

The bag was being shipped to New Jersey.

North Kansas City-based Helzberg Diamonds has its jewelry back and has promised to show the company’s appreciation to Lewis.

“I’m sure we’ll come up with a nice way to thank him,” said Helzberg Chief Executive Officer Marvin Beasley.
