It's ya boi, Ben Affleck. The iconic 2000s couple first met on the set of Gigli and, in 2002, Ben proposed with a (now famous) 6.10 carat pink diamond, created by Harry Winston. The coloured stone popularised tinted diamonds, with the centre rock flanked by two white baguette gems and set in a platinum band.
The estimated cost? Over $1 million. The couple ended their engagement in 2004 and JLo reportedly gave the ring back to Ben.
