Carnival-ish...like the word? It looks like watercolor paint in the design, but has an iridescent/opalescent sheen to it. The inside is white like milk glass, the rim is clear, and the outside painted and glazed or stained? I've never seen anything like it. It's unmarked, but it's a fun one because it's so pretty!
Very easy on the eyes. It's 7.5" tall with lid, 5.25" tall without lid.
