Vintage 1950's Hibiscus Brooch with Rhinestone Stamen

Vintage 1950's Hibiscus Brooch with Rhinestone Stamen I've been trying to figure out, for years, what kind of flower this is. The piece belonged to my mother. It seems to be a hibiscus with some added drama. It is 1 3/4" x 2 3/4". A silvertone stem decorated with small rhinestones, heads up to the goldtone flower with beautifully detailed petals drawn back. A large stamen in goldtone with a centerpiece of rhinestones sits at the top. All stones are there. A very unique brooch. in Good vintage condition.
