From our collection of classic solitaire engagement ring settings, this 18KT white gold low gooseneck solitaire measures 2.3mm wide at the peak of the shoulders, before the ring pinches to the setting, and tapers to 1.7mm wide at base of the band. The matching wedding band, W1272, is from our collection of simple wedding rings. While this setting is pictured with a 6 prong head (JTO), it can be ordered with a variety of heads to fit any shape/size center stone. Our engagement ring settings are also available in 14KT yellow and rose gold, 18KT yellow gold, and platinum. Center stone not included in carat weight.
