Set of 8 crystal champagne glasses cut around 1900

Set of 8 vintage champagne glasses. They are late 19th to early 20th century. High-quality and very fine work. Crystal model cut with braces. The décor and quality makes me think that this is a work of the crystal factory of saint louis. But they are not signed (were not signed at that time) It is worth noting a small burst on the edge of one (see photo), in excellent condition for the rest. Height: 10 cms. Foot diameter: 7 cms. Drinking diameter: 9.5 cms. Weight of 8: 1360g. 10421/2.
