I’m pretty sure the mosaic bracelet isn’t an arts and crafts project as it was in it’s own Roma box when i got it but,you never know!
The second brooch definitely isn’t from the ’40’s or 50’s,the clasp tells you that,in fact that dates it somewhere between 1870 and 1910.It is stamped with a triangle but it isn’t easy to spot!
And the bar brooch is sterling silver from the same time period.
Thanks for your help:D

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” !!
