Kris Humphries to auction off Kim Kardashian engagement ring

Kris Humphries is set to sell the engagement ring he gave to Kim Kardashian prior to their ill-fated 72 day marriage.

The NBA star is said to be selling the Lorraine Schwartz ring that he gave to Kardashian at an upcoming Christie’s auction in New York.

The ring is expected to sell for between $300,000 and $500,000- which is less than a quarter of the price that the ring was said to have cost originally.

An “impressive” ring made by Lorraine Schwartz, a designer and Kardashian family friend, is featured as part of the upcoming October 15 auction titled “Bright and Beautiful”.

Humphries has yet to confirm that he is selling his ex’s ring, and the owner of the item is only listed as “the property of a gentleman,” but the dimensions of the ring are the exact same as that of the ring that once belonged to Kardashian.

It is made up of a 16.21-carat rectangular cut diamond which is then flanked by a 1.80-carat diamond on either side.
