Birks Sterling Silver and Cut Crystal Ashtray. Vintage Mid Century Modern

This stylish and understated crystal and sterling silver ashtray is one of a kind! Stamped "BIRKS STERLING" on the silver frame, it has a cut crystal base and a single silver cigarette rest. It measures 3" in diameter and is in fantastic condition. I have seen this same design as a set of coasters and am guessing this is a matching ashtray to that set but have not been able to find another one.
