PRISTINE! Very Heavy Crystal Champagne/Ice Bucket with matching set of 4 Whiskey Tumblers (American Brilliant?)

This is a very heavy, substantial crystal champagne ice bucket with 4 matching whiskey tumblers in pristine antique/vintage condition. It's a WOW statement set that looks very much like American Brilliant cut crystal with elements of the hobstar pinwheel patterns throughout. It passes the ring test when tapped, sparkles in the light and would be a beautiful addition to a bar. I could not find a mark or an exact pattern match to confirm the maker so it's priced accordingly. Bucket measures 7 1/2" tall, 7" wide at top, 5 1/4" wide at base, and 9" wide from handle to handle. It weighs 8 lbs. Each tumbler measures 3 3/4" tall by 3" wide.
