Turquoise has been a persistent presence in jewelry because it carries cultural weight that most stones don't - it sits at an interesting intersection of Southwestern heritage and contemporary fashion. The lab-created version offers the same opaque blue-green color with consistent hue across every stone, which is actually an advantage in an eternity band format where stone matching is visible at close range. Rachel Zoe's design bezel-sets the lab-created turquoise stones around the full circumference of the band in 14K gold over sterling silver, the continuous color creating a strong visual statement that works as a standalone ring or as a distinctive stackable piece. Lab-created means consistent color, no treatments required.
