Rousseau Brooch Vintage Round with Gold Tone Swish Green Blue Rhinestones

Vintage Rousseau gold tone and silver tone brooch with blue and green rhinestones. Video is last picture. There is what I call a swish in gold tone with a little design. The swish goes over and under the circular silver tone piece that holds three rows of rhinestones - two green and one blue. The Rousseau hallmark is on the back. This is an estate sale find and in good used condition. All the rhinestones are in tact, there is some wear to the swish as you'll be able to see in the pictures. The pin has a little bump in it that can probably be carefully straightened out. Dimensions: 2-1/4"
