This is one of the bracelets known as all the colors of jade. In fact none of the semi precious gems are jade. When I started buying jade I was living in Asia and I saw all the quality levels of jadeite and nephrite and the prices. The bracelet listed has 2 purple amethyst, the white is tourmaline, 2 green chrysoprase, and the yellow is iolite. All are considered semi precious gems, and were tested by my Presidium Electronic Gem Tester. The fittings are sterling and marked 925 and FAS on the clasp. The bracelet is 5/16" wide and 7 1/4" long. Closes with a tongue clasp and 2 omega flips to secure the bracelet. Excellent vintage condition.
