Kim displayed a close-up photo of her ring on Instagram on Tuesday with the stadium screen in the background. She simply captioned the photo, "YES!!!"

Humphries, whom Kardashian filed for divorce from after 72 days of marriage in October 2011, proposed with a 16.21-carat center diamond and two 1.8-carat side diamonds from Lorraine Schwartz. (Kardashian, not Humphries, initially paid for the ring.) The ring's initial reported worth was $2 million, but sold for a total of $749,000 at a Christie's auction in New York City on Oct. 15. A portion of the proceeds from the sale was going to charity.

Though the rings may be similar, the proposals were very different. West popped the question in front of Kardashian's family and friends at AT&T Park in San Francisco by projecting "pleeease marry meee!!!" on the stadium screen. NBA player Humphries proposed in May 2011 in Kardashian's bedroom with candles and rose petals spelling out, "Will you marry me?" His proposal aired on an episode of Keeping Up With the Kardashians.
