One Ring 18k yellow gold, 1 princess-cut diamond 0.4 ct | Reference Number 10RG3901

A classic engagement ring with a new twist: the One Promise ring from the Fine Jewelry collection is adorned with a 0.40 ct princess-cut solitaire. The secret to its radiance is the discreet setting with four prongs, which allows plenty of light to shine on the diamond from all sides. Together with the twisted ring band made of highly polished 18k yellow gold, this piece of jewelry has a modern and timeless character. A ring you will never want to take off.
