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.

Desiree and Chris

Engagement announced: August 2013

Desiree Hartsock was the girl next door that got sent home after a dramatic hometown visit on Sean Lowe's season of The Bachelor. Luckily for her, she found love as the bachelorette with Chris Siegfried, who proposed on the finale with a platinum and 18K rose gold "Romantic Entwined Ring" with 3.70 carats of diamonds, including a cushion-cut center stone and 204 round-cut accent diamonds. The happy couple is now reportedly planning an intimate for next summer!
