Vintage Fashion Jewelry- flowers/crystal, 3 pieces

Matched set of 3 flower/crystal jewelry pieces. Stud earrings for pierced ears, bracelet, and double strand necklace. All items in original gift boxes. No idea of metal ... it is a dark brown color so plated something? Super pretty set. Necklace measures 16.5 inches (adjustable) and bracelet measures approximately 7 inches.
