antique glass butter pats, tiny plates diamond block & fan brilliant cut glass

Pair of small butter pat plates 3" in diameter - I believe these are probably American brilliant cut glass rather than EAPG. These sparkle like crazy, which I had a very hard time trying to show in the photos!

They have no sign of utensil marks or scratching from use, and just a few small roughnesses - no serious chips. Very pretty late 1800s vintage glass, hard to find these days.
