In the same way that lyrics and music effortlessly blend together, the 18k rose gold Tiffany Harmony® engagement ring pairs perfectly with its coordinating wedding band. The delicate four-pronged setting ensures the diamond shines brilliantly above the band and is complemented by the exacting proportions and tapered band of this ring that, when worn with its matching band ring, creates the perfect bridal duet. At Tiffany, we ethically source our diamonds. Integrity and social responsibility are at the core of our sourcing practices.
