for blushes I'd suggest reading bruises - a tendency towards a slight opaqueness caused by impact damage - and it may well be that a 'British' attribution, at least for States collectors, might enhance the value.
This 'point and arch' style of rim, along with 'Van Dyke' and 'fan escallop' are loft overs from the C18 - and were the sort of cut glass feature that the pressed manufacturers added to give a look of quality. However, I'd agree that it looks to be a pressed celery.
I don't know what C19 States pressed celeries looked like - maybe they were different to European - and combined with this style of rim suggests this to be British rather than American. Just my opinion though.
But the description certainly should win an award for exuberance.
