Shine in the Pandora Nova 14k Gold Lab-grown Diamond Open Bangle. This open bangle is formed from a flexible tube of 14k gold with a 0.25 carat lab-grown diamond at one end, creating an elegant yet dynamic design. The round brilliant excellent cut lab-grown diamond is held within an asymmetric prong setting that that gives the illusion of capturing a precious fragment of light. The 14k gold bangle is flexible and should not be bent or squeezed; simply twist and slide it easily onto your wrist. Style it alone or stack together with its 14k white gold counterpart for a mixed-metal look. Each Pandora Lab-grown diamond is treated with a post-growth color enhancement called annealing.
