Mid-century mod amethyst/crystal art glass dish or huge retro ashtray

Heavy handmade freeform glass dish or ashtray, Murano or Chalet glass style, not signed at all that I could see. It's about 9 1/2" across the widest point of the mod asymetrical shape, it very nice shape with only very faint surface scratching to the bottom underside where it stands.
