Colored glass lampshade

Here is an object that keeps its mystery… I think it is a lampshade, but you will have to find the right base, or perhaps you have it and broke the lampshade. It can also be used to “top” a tea light, or simply placed on a shelf as a decorative object. I found it for its pretty colors and because I like investigations, but I must admit that this time, the investigation has not yet brought absolute certainties, nothing absolutely similar on the web, but some leads that evoke Murano glass. It is therefore a priori a molded glass lampshade composed of a multitude of pretty colored pellets, slightly iridescent. It is in perfect condition, no cracks or chips. It measures 12 cm in height, 14 cm in maximum diameter, 5 cm in diameter for the upper opening and 6.5 cm in diameter for the lower rim.
