I don't Think this would be considered as American Brilliant Glass. Sometime this can be hard to tell from a picture for sure. First American Brilliant glass is late 1800's to early 1900's in age, and is cut glass or crystal glass. Run your fingers along the design motif and if it has sharp edges it is cut, from the picture it appears your is pressed crystal or Glass. Under most cases This early glass will jump out at you, far more then the contempory glass of today. So much of this pattern glass is around, that it can be hard to find the maker, if no marks are apparent. There are 100's of Crystal Glass and Glass makers making what is considered as pattern glass. Yours would be considered as a compote or sometimes called a comport, and it appears to be Crystal Glass, a light tap on the edge with a fork, and listen to the sound will tell you if it is crystal and after a while even the quality of the crystal. The quality will fall into 3 basic catagories, Glass, Crystal Glass, and Lead Crystal. Hope this helps a bit.
