Kris Humphries puts Kim Kardashian's $2 million engagement ring up for auction: Report

A sparkling engagement ring matching the description of Kim Kardashian's symbol of marriage has been listed in an auction called "Magnificent Jewels" that’s slated for Oct. 15 at Christie’s in Manhattan, according to RumorFix.com. The high-end auction house declined to name NBA player Kris Humphries —Kardashian’s ex-husband — as the seller, saying only that "a gentleman" was behind the listing.

The former Brooklyn Net and current Boston Celtics' forward presented Kim K with the ring on her reality show Keeping Up With The Kardashians.  Their August 2011 wedding was featured in two separate and highly viewed E! specials and lasted a whole 72 days. Their divorce came a few months later.

After filing for divorce, 32-year-old Kardashian wanted to keep the ring but Humphries sought the jewel’s return as part of his fraud claim.

The Lorraine Schwartz design features a 16-karat emerald cut center stone flanked by 1.8-karat trapezoid side diamonds — in case you are in the market for some tainted bling.

The ring goes on view Oct. 11 at Christie’s in Rockefeller Center and is expected to fetch only about $500 K.
