vintage metal black white gem boho asian bracelet

rare bracelet with beautiful white & black stones(possibly mother of pearl & onyx). approximately 8" long. stamped HAN China. I was told the bracelet is sterling silver but without the 925 stamp I can't be sure. *please view photos carefully before deciding to buy* it's very tarnished but could probably be cleaned up by polishing. please don't hesitate to make an offer on one piece or multiple items in a bundle. all reasonable offers will be considered. thank you for looking🤍🖤
