Antique Bar Brooches Pot Metal C-Clasp Barrette Hair Pieces Silver Bow

This is an interesting lot of vintage and antique jewelry pieces consisting of 2 c-clasp brooches and one clip, or clasp or barrette. I'm really not sure what it is used for. Please see pictures. Condition - excellent The first piece is a 3 looped rings made in what appears may be copper. I don't believe it is rose gold. C-clasp. Very small. It would like neat on a collar. Condition - excellent, a little darkening near the clasp on the underside. .75" The second piece is a silver bow style clasp or barrette. I'm not sure how this is used but could clasp together strands of a necklace or used in the hair. See the clasp. No markings but it looks very much like silver to me. I have not tested it. Condition - excellent 1.25" The third piece is silver bar pin or brooch with a c-clasp. It is set with shiny pieces that may be mica or mirrors. They are not faceted. I am unsure of the metal type but it may be pot metal. Condition - excellent 2.75" jewels3-32 checked
