Some finds from a $5.00 bag of broken jewelry

I spent yesterday going through a one gallon ziploc bag of broken jewelry. I did find a Beau-Ster sterling and enamel pin in perfect condition, as well as 2 pairs of Monet earrings.

Of the jewelry that needed repair: One Marvella jadeite glass brooch, missing 6 faux pearls (4 were in the bag) and the bottom 5th of the jadeite was missing. I replaced the missing part with some green jadeite beads I had, then I reconstructed and filed the pieces to conform. I'll probably etch a little on it today.

There is a mystery sterling flower 6/8" with pale blue rhinestones. I had no blue stones, but I found clear rhinestones in the bag, fortunately the missing rhinestones were opposite each other, so the two clear rhinestones are symmetrical, which goes with this pin-- kind of, good enough for me to wear.

Also, a mystery scarf pin--fangs on the back?-- silver-tone and rhinestone, replaced missing rhinestones.

Finally, the starburst brooch which had a cheap, scratched pink stone in the center, also missing rhinestones. I almost put this brooch in the scavenge pile, but upon second glance, I noticed that it was just in need of TLC. I tested the awful stone in the middle, plastic. Since it was a scrapper anyway, why not replace the stone. I had a carnelian from an old pair of earrings, and voila, wearable and attractive.

Anyway, that was my $5.00 gamble. Any clues as to the provenance of the Starburst, flower pin, or the scarf clip would be greatly appreciated.
