Cobalt blue swirl scalloped edge art glass bowls set of 2

Beautiful pair of art glass bowls with a cobalt blue swirled and scalloped edge. Flat bases not polished. Heavy pieces. I would consider these to be dessert bowls. There are no chips or cracks in either bowl. Both bowls have bubbles and imperfections within the glass. One bowl has a black speck in the glass. The other bowl has an area with slight scratching and very faint marks on the base that looks like market. Unsure. Hard to photograph but can be seen in the photos. Request more if unsure. Otherwise these area a gorgeous set of cobalt blue art glass bowls! 5 3/4” diameter 3” tall
