Q: This G. Argy-Rousseau lamp was a wedding present to my parents in 1929 and all my life, my mother has asked me to be careful of this lamp! I don’t know whether to keep it or auction it. There is a globe inside the lamp and a small glass cup for holding perfume. When the globe is turned on, you notice the lamp is an amethyst color with dark red flowers. The shade is in perfect condition but the perfume cup has a small chip on the outer rim. The lamp is 7 1/2 inches high and the shade itself is 7 inches high. How much is it worth?

A: G. Argy-Rousseau (1885-1953) was a French glass artist who made a variety of objects in the Art Deco style. In 1921, he formed a partnership that made pâte-de-verre and other types of glass. Pâte-de-verre means “glass paste” and is made by mixing powdered glass of different colors, pressing it into molds, and firing it to blend the colors. The partnership ended in 1931 and he opened his own studio, where he worked until 1952. A pâte-de-verre perfume lamp by G. Argy-Rousseau would sell for over $2,000.
