These are likely later Brilliant period, 1900-1915. Could be American; English also possible; I think Continental is less likely. There an image of a Stourbridge piece in this pattern (Harvard) in Hadjamach, but it looks to me like the crosshatching is left/right and up/down, rather than diagonal. Harvard was first used by Hawkes around 1900-1910.
The deep sharp quality cutting along with the thick wide foot is typical Georgian glass c1800
Definitely not Georgian! Neither the pattern or this type of rich cutting was done that early. Georgian patterns are simple by comparison.
Deep cutting was also popular in the 1930s but the cutting is usually not as sharp due to the cut piece dipped in acid to give the final polish, before this the piece was hand polished which was the most time consuming job.
Acid polishing was widely used in the US beginning around 1900, and acid polished pieces can be very sharp. The good quality ones were hand-buffed after acid polishing, as acid often left an unwanted pitted or watery texture on the surface. Some English or Irish pieces with cuts that aren't very sharp may have been fire polished. Waterford fire polishes their cut glass, though I don't know when the practice started.
