I believe this was made in the Fredrick Carder era, circa 1930's; Corning N.Y made in USA. It has a ribbed pattern that makes it look scalloped, with a rolled edge rim, just gorgeous! Comes with underplate or drip bowl, it has a recessed center. The plate is 6 1/4" wide and 1" deep. The bowl is 4 7/8" wide and 2 1/2" deep. I have more Steuben glass listed in my store, also a large bowl that matches this color and pattern. Please take a look in my store, I have many vintage items. Thanks!
