Vintage Silver Tone Rhinestone Flower Brooch Large

This belonged to my mother in law who was born in 1942.

I'm not sure if it was hers or passed down from her mother/grandmother.

It does have an aged patina.

Lightweight like aluminum.

I would guess it's from the 1960s or before, but not sure.

Unknown metal, has silver tone.

Some tarnishing spots as shown in picture.

Approx. 3 inch width.

This item is sold from a vintage boutique in Hanson, Massachusetts.
