Pierre Signed Rhinestone Pin RARE Signed Vintage Costume Jewelry Scorpion ?

Rare, vintage signed brown taupe, citrine and aurora borealis rhinestone pin. Signed Pierre. I couldn't find anything on Pierre until I contacted a jewelry identification website.

The gal told me that Pierre was a company in Canada and may be connected to Sherman. Sherman made quality pieces and is very collectible and sought after. The stones used are the same brilliance and quality as Sherman and some of them are open backed. The pin measures 2 1/4" long. Some minor wear to the aurora finish. No big whoop! The marquise stone points are all in tac. It kind of reminds me of a scorpion.

I only have two other pieces of Pierre. One other brooch and a stunning duet dress clip set that I purchased in Canada. They are listed in separate listings. So you may want to check those out also.
