has a sort of angular and simple art deco appearance - I like it, but as for maker, sorry, not a clue. I'd suggest opalescent rather than opaline, but stand to be corrected on that. May we please see a picture of the underside if possible, and is there any wear, and is there a 'sunset glow' when held to a strong light? It won't help remotely with attribution etc., but folks here are usually keen to know the dimension/height.
