mod vintage art glass ashtray, Murano red / pink opalescent cased glass

Beautiful unusual color on this vintage Murano glass ashtray - it's a opalescent white to pale pink over the red. It's not marked or signed that I could see, though it's probably 1970s, I think.

It's heavy and solid, measures about 6 1/2" long x 5" wide. There's a few light scratches to the interior, and scratching to the bottom where it stands.
