Crystal Fruit Bowl Rolled Rim ID? DATE?

I'm stumped, can you identify this beautiful HEAVY CLEAR cut crystal fruit or center bowl with rolled rim? It is 7" in height, approx 8" diameter. The base is hexagonal with a polished "pontil". Hollow stem! Can't find a mark, so far anyway. I found (online) two similar pieces shown on completed Skinner auctions described as "Anglo-Irish 19th century" but those had a square base. Also found a completed listing on RubyLane antiques website of a similar rolled edge piece (tulip vase) with fluted cuttings, described as Dutch circa 1836, this one had similar cuttings but on a sterling silver base. I see Dorflinger made some rolled edge pieces; I see Baccarat often made pieces with a hexagonal base. Thanks in advance to anyone who can identify and date this beautiful item.
