"Bennifer," the 6.1-carat pink diamond engagement ring actor Ben Affleck bought for Jennifer Lopez, is on the block a year after the couple broke up.

New York Jeweler Harry Winston reacquired the ring, which has a price that's available only to "serious buyers," a spokeswoman for the jeweler told World Entertainment News Network.

Lopez reportedly gave the $1.2 million pink solitaire dubbed "Bennifer" back to Affleck when they split up in early 2004.

Lopez married salsa star Marc Anthony last June. Affleck has been dating "Daredevil" co-star Jennifer Garner.
