Vintage Italian green red marble onyx round ashtray heavy

First picture is bright overhead light, the rest are in natural lighting. Gorgeous green and red Italian marbled onyx ashtray. Perfect condition. This ashtray has the most amazing colors and patterns. Reds and greens stripe a lovely cream color. Carved rim around the bottom. Fairly heavy. Beautiful on a stack of coffee table books, or on a bookshelf. Part of my Round Top, TX collection
