Pearl and Multiple Gemstone Flower Golden Pin

The item you are looking at is a multiple gemstone flower pin. The pin is golden in tone but I do not believe it is real gold or gold plated. The pin has a blue, green, red, purple and champagne brown. The pin also has three flowers with pearls as the center. The pin is 2.75 by 2 inches and is in good condition. The pin seems to be missing a gemstone, the smallest one, and im sure anything could replace.
