Heptagram 7 pointed star plate Handpainted very rare OOAK

Have you ever spent a long time researching and writing something only to have the page disappear? This is a mysterious plate whose origins are uncertain, although very old it has no flaws & the back of the plate has no markings. It’s about 8 inches diameter and could be from Israel because the seven pointed star is Used in the Kabbalah. However it could be from Persia or some other place. If you know please share with us. I don’t recommend it as a kitchen item because I believe it to be more of a work of art. Extremely rare.
