Vintage Bracelet Shell? Very Light Pinky Cream Tone

Inner circumference measures about 7.25". Metal has heavy discoloration/tarnish.

Preowned vintage 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.
