This is a very unique and beautiful ABP American Brilliant Cut Glass low bowl with shallow sides. We do not know the maker or pattern for this piece. It has a unique, squared stepped edge. It features a deeply cut, mini stars inside cut diamonds shapes. In the center of the dish is a grid of mini stars and cross hatched squares. This bowl measures 6 7/8 inches in diameter, is 1 7/8 inches tall and is a little over 1/4 inch thick. This bowl is in excellent condition, very clear and bright. No cracks, 2 square stepped tips have slight flake chips, one to the inside of the bowl and the other to the side. There are some wear/rough spots on various other tips around the bowl. The edge is very nice overall and does not lose its shape. This terrific, well-made bowl is a 'must have' for any brilliant cut period glass collection!
