Drinking service - cut crystal - Belgian Art Deco glassware

Magnificent set of 6 antique stemware glasses in cut crystal of Art Deco style, Belgian-made from the early 20th century, circa 1900-1920.
The shape, size and quality of the crystal strongly suggest a Val Saint-Lambert production, though not with absolute certainty
These elegant glasses are distinguished by their cut decoration with geometric lines characteristic of the period, as well as by their particularly refined faceted stem. The crystal is of remarkable quality, perfectly clear, transparent and luminous. It offers superb brilliance as well as a clear and crystalline tone, characteristics of fine old productions.
Under a 365 nm UV lamp and in total darkness, the crystal shows a green fluorescence characteristic of manganese, a decolorizer frequently used in the manufacture of quality crystal in the early 20th century
