Most of the Stavangerflint and Figgjo Flint pieces I find are utilitarian - dishes, serving pieces, etc. They did produce purely decorative pieces as well, though, such as this small vase. It is marked Turi, Figgjo, Norway on the bottom.
One of the artists at Figgjo was Turi Gramstad Oliver; I don't know if this is her work, or simply named after her. I would assume it is hers - maybe someone can let me know.
