One is also vintage '80's, a dragonfly pin with Gripoix glass, by Deanna Hamro. I can't find too much info about her, except that she designed costume jewelry in the 80's & 90's, but otherwise designed fine jewelry.

The other is a Christian Lacroix sun pin, which I think may also be vintage '80's. I will probably sell this one on Ebay, but keep the Hamro.

I love how glitzy and glam the '80's were. Makes for great statement jewelry!
