Purchased at an antique mall while living in the United States. It has been stored at home without being used after purchase. Fire King Jadeite Jane Ray Dinner Plate Diameter: 23cm, Height: 2cm No markings. No cracks or chips. Overall, it has a shine, but there are manufacturing-related hairline cracks, unevenness in the glass, and white spots. There are also cutlery marks.
