This necklace was designed very carefully so that the balance of each design element is pleasing to the eye whichever way you would like to rotate it. The first two photos show the necklace with the clasp directly at the back of the neck. The photos after that show the necklace rotated in various ways with the clasp showing in front. Decide which way is your favorite, or switch it up every time you wear it. Total length is 19.5 inches - this one is not length adjustable due to the design.
