Kim Kardashian was in Chicago Tuesday night to help promote a contest being held by renowned jeweler Michael Hill.

Kardashian, wearing a serious (borrowed) rock, was promoting the "Search for the World's Best Couple" contest being held by Michael Hill jewelers.

The winner of the competition will receive an extremely rare sparkling 22.25 carat diamond ring. The ring will be presented to the winners at an exclusive ceremony on Dec. 16 in Chicago at Water Tower Place.

"The contest is open for couples whether engaged, married or even just romantically inclined to enter," Hill told NBC Chicago.
