Murano style hand blown art glass ashtray unsigned, aqua waves w/ yellow colorful glass

Beautiful beachy colors on this hand blown art glass ashtray! It's not signed, has no label - I don't know the maker or exact vintage of this piece, though it looks like Seguso to me. It's in very good condition, interior free of scratching or wear. No scratching to the bottom, though there's a couple of inclusions from manufacture. Measures 4 1/2" square, 2 1/2" tall.
