This is a very cool bracelet Made up of double swirl/ spiral shapes. Each one linked to the next…There are no rough edges.No hallmarks,had it tested at 925 sterling. It measures 7 1/2” long x 1” wide. The way it is constructed,it can easily be shortened,by taking a link or two out. One end is closed.the clasp is a hook…..it has not been cleaned,polished,altered or repaired..I left it au natural…..Check the pictures as they are part of the description…Ask questions prior to bidding..No refunds no returns..Thanks Tina Allthatshimmers
