Stone Stretch Cuff Bracelet NWOT

This what I believe is natural stone with a bone color with brown veining throughout. I am not sure if it’s natural stone but it is cold to the touch and has some weight to it. Banded together with a double stretch band this cuff bracelet is such a pretty statement piece. Stone pieces are 2 3/4” wide with a 3” opening unstretched. NWOT
