Inspired by BIRD OF PARADISE, the design draws from their colorful plumage, gracefully curved beaks, and jewel-like eyes. The square-shaped ring is defined by geometric forms, with a line of yellow gold evoking the crest feathers that appear only in special moments. - Made in Japan.- 925 Sterling Silver, 10K Yellow Gold.- Ring band width 1.26cm(approx.)- US sizing.
