The Tiffany® Setting Engagement Ring in Platinum

Style # 1
2 Carat

A true design masterpiece, the Tiffany® Setting is the world’s most iconic engagement ring. Flawlessly engineered, the six-prong setting virtually disappears and allows the brilliant diamond to float above the band and into the light, resulting in a ring so beautiful it has been a symbol of the world’s greatest love stories for over 130 years.
