We are absolutely in love with these pieces of circa 1970s jewelry. They are very tribal looking with their brass patinated finish and chunky graduated coils and little ball tips. The choker has a 5.25-inch diameter, but its spring-like coils allow it to spring open to accommodate a larger neck as well. The diameter of the coil graduates from .25 inch at either end to .75 inch in the center.  The bracelet is 3.5 inches in diameter and fits me more like a bangle than tight like a cuff. It also springs open to easily slip onto your wrist and to accommodate a larger wrist as well. The diameter of the coil for the bracelet is the same .25 inch at either end and graduates to .5 inch in the center. This stunning set should be yours!
