The "E80" stamp on the inside of a gold ring typically indicates the metal's purity and the manufacturer's mark. The "E" could represent the jeweler or brand, while "80" usually signifies that the ring is made from 80% gold, which corresponds to 18 karats. It's important to verify with the jeweler for specific meanings, as hallmark conventions can vary by region and manufacturer.
