When returning unique jewelry items, or items containing a 1.00 ct center diamond or larger, Costco warehouses may require additional time to verify the diamond, in which case a refund will be approved upon positive verification and as long as the item is not damaged or changed in any way (i.e. resized or reset). This process may require two to five business days.
