Finding another identical is not necessary for value !! You want similar size, condition, similar time period, and similar mounting (sterling) !! I only found one and they were asking $135. !! But with the number of new Wedgwood pieces on the market I think getting that amount may be difficult !! But give it a shot,, you never know !! Use your best marketing skills and make your description sound like its one in a million !!

This may help you,, much easier to understand that the others !! From what I can tell your bracelet was probably made around 1920 but I can not see the mark to be sure !! Read about the additions and see if your mark fits any of those !! Especially the little mark that is under the Wedgwood name !!
There are pics that you can look at to see what it should be !!
