I believe this was originally Steuben, but I have looked and cannot find it........and it is about 100 years old. Im fairly sure it is American, but I am stumped. Excellent condition and finely formed and quality champagne stem. I cannot see any makers marks obviously. I believe it is clear cased cranberry glass on the bowl......stem is completely clear as shown. Great form and excellent quality. About 5 5/8" tall and 4" diameter bowl.
