These gold hoop earrings are crafted from 14K yellow gold, giving them a luxurious and elegant look. Made in the United States, they showcase a classic style that is versatile and timeless. The high quality metal ensures durability and a beautiful shine, making these earrings a perfect accessory for any outfit or occasion. These were my mom's who wore only gold. I do not see any markings, but I do not know where they would put a marking on these. Returns accepted in case I am wrong :).
