Lost round silver bracelet in Oxford

Please help! I lost a round silver bracelet in Oxford between 10.30 AM and 7.30 PM on 22 March, likely while cycling between Mount St/Jericho and Manor Rd/St Catz (via Lamb and Flag passage), or between Manor Rd/St Catz and Hill Farm/Marston (via the Marston bike path starting at Uni Parks, Crofton Road Playground). The bracelet is a bit less than half an inch of width and has a woven pattern in the middle (see photo). It has a stamp with 825 inside. It is jewelery I inherited from my late mum, so has huge personal value. REWARD OFFERED! Please email [email protected]
