This is a gorgeous bracelet, blue with a luminescent, tiger's eye quality. The material is a hard plastic, and I am uncertain how it was made to incorporate the changing tiger's eye patterns. The bracelet measures 2-1/4 x 2-1/8 on the inside, and is 1" wide. It has a slide-in clasp, and also a safety chain. The inside of the band is marked "Hong Kong." There is some slight age-related wear on the inside of the band, but otherwise the bracelet is in excellent vintage condition. The pictures do not nearly do it justice. It will be shipped in a gift box.
