It is similar to murano, but could also be by moser or Václav Hanuš, bohemian glass.
It is light purple / violet colour.
Beautifully cut glass that shines on every angle.
It is 1960s.
It is in good condition for age, but it does have scratches, mainly underneath and some small chips on the spikey corners, shown in photos. Tiny chip on the top edge. Overall a really special ashtray!
