Vintage Blue and Green Rhinestone Silver Tone Brooch

This fun vintage brooch features a center collection of marquis cut rhinestones of 4 bright blue, 3 yellow green and 1 soft aqua. The center rhinestone does appear to be glued so this might be a possible replacement. These rhinestones are above a silver 4 cornered design of curling shapes and more green and blue round rhinestones. The brooch is approximately 1 3/4" square and rises about the same 1 3/4" depth, and has a rollover safety clasp. My sister-in-law was an avid collector of so many things, jewelry was just one category. She knew everything about each and every one of her pieces but unfortunately she is no longer able to tell us. I'm not an expert - I just offered to help find new homes for her beloved pieces. This is a vintage piece and has evidence of wear that is appropriate for its age. Please examine all photos closely for condition.
