1. Tiffany Bezet Yellow Diamond Ring
While it’s not technically from the Tiffany engagement collection, it’s still qualifies, in my opinion, as one of the prettiest and most unique engagement rings with colored stones. The brilliant yellow diamond is available in a range of carat sizes, from about a quarter-carat to more than two and half carats, cushion-cut in an 18-karat yellow gold bezel setting. How incredibly gorgeous!
