Vintage French Possible Louis Rousselet Glass Dangle Brooch (A1785)

Vintage French Possible Louis Rousselet Glass Dangle Brooch Size: 2.75". Color: Gold; Pink Condition: Very good vintage Signed: Brevette S.G.D.G. Details: Beautiful glass, The clip is marked Brevette S.G.D.G. Very unique; not sure what the clip is; it does not move. It has a trombone c clasp. The metal work looks like Rousselet, but I could not confirm. The bottom piece is moveable. Please look at all the photos, as they are part of the description. I try my best to point out any flaws. Also please remember this is a preloved piece and may show signs of light wear, marks, scratches, etc. I will be posting a lot more jewelry, Keep checking back.
