One reality star's trash is another person's treasure?
The Lorraine Schwartz ring, which features a 16.21-carat center diamond and two 1.8-carat side diamonds sold for $620,000. Adding in Christie's markup, the anonymous online buyer will pay a total of $749,000 — still a big discount from the ring's initial reported $2 million price tag.
It was first reported last month that Humphries, 28, planned to sell the ring with which he proposed to Kardashian, 32, in May 2011. The couple, who split after just 72 days of marriage, finalized their divorce in May of this year.
