Ann Vien was a jewelry designer in Atlanta and her output was small. This is the second Vien piece I have found. The other was a bracelet made of aluminum. Nevertheless, her pieces command a surprising prices for a relative unknown. She has a bracelet set in Simonds, Collectible Jewelry, page 74, and a pair of earrings in Pittman, Jewelry Box 3, page 213. These earrings have 4 emerald cut rhinestones in red and green, 1" by 7/8". Marked Ann Vien on the clips. Excellent vintage condition. I feel a collectible urge coming on. Please contact me if you have information about this designer.
