Joyce Chen Japan small ceramic Tea Cup vintage 2001 never used

Hand crafted small ceramic teacup by Joyce Chen Pottery Japan. My college boyfriend bought this for me at the Providence Place Mall Rhode Island in November 2001. I never used it, and we broke up over 20 years ago. Has been sitting on a shelf in my Mom’s house since then. It is a beautiful Forest Green base with a taupe ribbon pattern. Very nice, perfect condition. About 3 inches tall
