Vintage Flower Starburst Brooch Pink Gems With Gold Color Tone

A flower shaped brooch. 

This brooch reminds me of a starburst. It is so pretty with pink gems and one white pearl type piece in the middle. It has gold tone leaves around the petals. Measures approximately 2.25". We obtained this item from an estate sale among other vintage jewelry pieces. It looks like there might be a makers mark on the back but it is hard to tell.
