We recently reported that Emily Maynard is feeling super giddy these days about her man and her ring… and now we know why! Not only did the Bachelorette accept a proposal from Jef Holm while filming the show’s finale in Curacao, Wetpaint Entertainment can exclusively reveal that her engagement ring is the biggest and most expensive in Bachelor/Bachelorette history!

“It’s huge,” a source confirms. “It’s 100 percent the biggest any woman has received on either The Bachelor or Bachelorette.” We’re told the main stone, like Emily, is quite unique. It’s a very rare, geometric shape. And the band is made up of pave diamonds. Its retail value? Over $150,000.

Luckily for her Jef, he’s doesn’t have to pay for it all by himself. We hear he’s getting some help with the hefty bill.

As for Emily, we only have one piece of advice: insure that rock of yours… fast. And once you do, never take it off!
