De Beers deeply appreciates the transformative quality of diamonds - each stone is individually selected and cut by master diamantaires to ensure they're "as unique as its wearer." This 'Arpeggia' choker is crafted from 18-karat white gold and encrusted with 5.97-carats of round brilliant-cut diamonds that graduate in size to evoke the rolling notes in Beethoven's 'Moonlight Sonata.' It can be worn as a whimsical headpiece, too.
