Art Deco Carved Glass Mirror Terrier Dog Brooch Pin Unique Early C Clasp 1930s

This is a odd( In a good way) Pin

I have never seen another

I tried to capture the reflection in photos

It is a carved glass mirror Dog

Made specifically the back is a quality similar to rhodium plated typical of the 1930s pieces

C clasp

Very unique

Maybe French?

It’s something unique for sure

Good condition overall

Light age

In person it looks better than photos I have to admit

Research wise I have not found anything close to it
