Nine West Stretch Bracelet Silver Tone with Blue Gem

Nine West Stretch Bracelet Silver Tone with Blue Gem Inner circumference measures about 7" unstretched. I am unsure of the material of the gem. Light marks and signs of wear. Preowned bracelet, sold as shown - I am unsure of material type(s) because of this. Pictures show different angles for you to review - while I attempt to note any defects, some tarnish/signs of wear may be visible that are not otherwise stated.
