A diamond is forever, but most reality TV engagements aren't. That doesn't mean we can't have some fun revisiting the stunning rings exchanged over the last two years by former Bachelor and Bachelorette contestants, though.

DeAnna and Jesse

Engagement Announced: July 2008

Called off: November 2008

When DeAnna became the Bachelorette (having been jilted by season 11's Bachelor Brad) she accepted surfer dude Jesse's proposal, along with a 2.5-carat princess-cut diamond ring set in platinum by Tacori, which she wore during their five-month engagement.
