French Paperweights by Saint Louis (Compagnie des Cristalleries de Saint Louis). One of the greatest glassworks of all time, Saint Louis, located in Moselle, Lorraine, France, began producing crystal paperweights in the 1840s. They continued producing fine paperweights until about 1867. Due to increased collector interest, Saint Louis went about the task of re-learning the art of crystal paperweight manufacture in the early 1950s. An estimated 300-400 lampwork and millefiori weights were made there between 1952 and 1955. Paperweight production resumed at Saint Louis in 1965 and continues to the present, with most weights produced in limited edition.
