American Brilliant Cut Glass refers to a style of glassware produced in the United States from the late 19th century to the early 20th century. This glass is characterized by its intricate designs, deep cuts, and brilliant clarity, often resembling diamonds. It was primarily made from lead glass, which allowed for the sharp, reflective surfaces that define this art form. The production of American Brilliant Cut Glass peaked between 1876 and 1910, with many artisans and factories contributing to its popularity. Notable manufacturers included Steuben Glass Works and Libbey Glass Company. Today, this glassware is highly collectible and valued for its craftsmanship and historical significance.
