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 !!
