Set of 18k Diamond White Gold Stacking or Wedding rings

Matching set of 18kt white gold with diamond rings. A lovely open filigree design and diamonds go 3/4 of the way around the rings. Approximately size 7 - 7.25 (see picture) The last picture is a picture of the stamps that were on the rings before I got them sized up (which took the stamps off) Last photo - to show how they look with an engagement ring using another ring I have for sale.
