Crystal Saint-Louis? Set of 4 antique crystal stemware etched with acid foliage 1900

This superb set of 4 stemmed glasses is a creation of a cristallerie, probably from saint-louis or baccarat.

These stemware with molded stems and rims decorated with scrolls of detailed flowers and foliage are embellished with a delicate acid engraving, called "rock crystal engraving". These glasses are in beautiful condition; they measure approximately 11.5 cm in height X 5 cm in diameter. These glasses are not stamped.
