Val St. Lambert Intaglio Frosted Crystal Mallard Duck Paperweight

This is a vintage clear and frosted crystal art glass paperweight, commonly attributed to the Belgian glassmaker Val St. Lambert. The item features a freeform, asymmetrical shape with a flat bottom and a curved, faceted top. The focal point is an intaglio-style engraving on the reverse side, showing two mallard ducks or waterfowl swimming. The design utilizes a contrast between polished clear glass and frosted/acid-etched textures to provide depth and detail to the feathers and surrounding water scene. The piece appears to be heavy, solid crystal, measuring approximately 3 to 4 inches in width. The craftsmanship is indicative of Mid-Century Modern European glass production, likely dating from the 1960s to 1980s. Notable features include the smooth, beveled edges and the intricate internal relief work. While the surface shows some light superficial scratches and shelf wear on the base, it remains in generally good condition with no major chips or cracks visible in the provided image. There are no immediate signatures visible from this angle, though such pieces are typically signed with an acid-etched mark on the base.
