Gold Tone Rhinestone Flower Brooch Cameo Middle

A little bit of a different cameo brooch than others that I have come across. It is very pretty. Overall, it is in nice condition with good bones. A couple petals has a tiny spot of verdigris that would need some TLC and paint touch up. I am having trouble discerning the rhinestone spot on the cameo, even with a magnifier. I believe it may half broken off.
