OK !! Lets start with the mosaic bracelet,, it is from the 40`s and was someones craft project !! You could buy the blank bracelet forms and the beads to make your own !! Some were sold in kits with everything needed and a pattern which was not always strictly followed !! Trust me,, it gets a bit boring using a sewing needle to pick up and place all those tiny beads !! You can see the centers are not exactly full or as well placed as they should be !!
The next is the rhinestone broach which is about the same time period say 1940 to mid 50`s !! No mark which was not unusual but still nice costume jewelry !!
Then the good one !! This looks like early 1900`s but can not see the name well can you try to take a better pic please !! It may only say “Sterling” !!
