"We've just been quietly enjoying it," David tells the site, even revealing the work he put in to choosing the perfect ring for Bitsie.

"It's over a hundred years old," the bride-to-be shared. "The diamond is from the 1890s, and the setting is from 1915, which is the year my grandfather was born."

Stunning! Congratulations to the happy couple!
