Red Raspberry Murano Ashtray Blown Art Glass

I'm not absolutely sold on this being Murano, but can't make an ID. I'm wondering if it's possibly Chribska or even someone else. The bottom is clear and unsigned. That said, you be the judge! It has 3 cigarette divets. It is free of all imperfections and measures 4" at the longest possible and 1 1/2" tall. Size: 4" across Condition: Pre-Owned Like New No imperfections I can see or feel.
