This is a beautiful brooch. I believe it is from the early 1900s, possibly Victorian and the two pear-shaped pearls are freshwater pearls. The brooch is a rose gold color which I am assuming is gold fill and the fancy leaves in four places are lighter more yellow color. Victorian women were known to wear the necklace AND the brooch at the same time, along with other "bits". They loved their jewelry. It has a "C" clasp and a longer pin as in Victorian times. There is a small dent in the back near the hinge - please see my picture. The length is 3 inches and 1 1/2 inches wide.
