"Bachelorette" fans rejoiced Monday night when Desiree Hartsock accepted a proposal from Chris Siegfried - and the 3.7 carat Neil Lane engagement ring that came with it wasn't too shabby either.

"I wasn't even paying attention to that!" Hartsock told ABC News Tuesday. "[But] it's a story, actually."

The bauble, which is comprised of intertwined platinum and rose gold bands, more than 200 small diamonds and a cushion-cut stone, was one of "a bunch" of options, Siegfried said, but this one had special meaning for him.

"I chose this ring because the bands are tight-knit and I felt like those were kind of like stories of both of us coming together," he said. "And all the jewels leading up to the single diamond are little experiences we've shared along the way. And it comes to one and that's the new experience we're sharing together."

"He's so romantic," added Hartsock. "I think he was so excited to tell me [his explanation] that he told me right after the proposal. He was like, 'There's a meaning behind it,' and he went into it."

There were aesthetic reasons behind his choice too. Not only is Hartsock a fan of rose gold, but Siegfried liked the effect it had on the sparkler.

"It kind of dulls it down and I didn't want it to be super powerful and bright for her," he said. "It's a big ring and it's showy but the rose gold kind of tames it."

Hartsock agreed - and added that when she did take the time to inspect the ring, she was thrilled with her fiance's choice.

"In the box it was like, huge," Hartsock said. "I was like, 'Oh my God!' [He's] the best. The best. The best."
