Art glass decanter and tumbler set in the manner of Schneider or Le Verre Français

This set appears to be a seven-piece glass service featuring a central decanter with a matching stopper and six small drinking tumblers (arranged in three stacks of two). The glassware is characterized by a matte, frosted, or 'acid-etched' finish with a mottled color palette consisting of soft lavender and purple tones blended with cream or pale yellow inclusions. The decanter has a rounded, bulbous body that transitions into a long neck with a flared rim. Stylistically, the set is highly consistent with early 20th-century Art Nouveau or Art Deco 'cameo' or 'marbled' glass, specifically such as the 'Charder' or 'Le Verre Français' lines produced by the Schneider glassworks in France. The surface features organic, abstract patterns that could be interpreted as stylized floral or botanical motifs. No maker's marks, signatures, or etched names are visible in the provided image; therefore, attribution to a specific glassmaker remain as a hypothesis. The craftsmanship suggests a high-quality hand-blown or mold-blown technique common in high-end European art glass from approximately 1910–1930. The pieces appear to be in good visual condition with no obvious chips or cracks visible on the exterior surfaces, though the matte finish can often hide minor surface abrasions or interior mineral deposits.

I have examined the images of this seven-piece art glass service. Based on what I can see, the set exhibits characteristics consistent with the 'mottle' or 'intercalary' glass techniques utilized by the Schneider glassworks, potentially under the Le Verre Français or Charder lines. I observe a matte, acid-etched finish and a color transition from lavender to deep purple that is typical of French art glass from the 1920s. However, I cannot verify the presence of a signature or mark from these photos, and I cannot confirm the internal glass structure or weight without a physical inspection. The appraisal value of $1,200 - $1,800 is based on the hypothesis that this is a period-correct, multi-piece set by a major French maker in good condition. This value reflects general market interest in complete sets, which are rarer than individual decanters. This estimate is entirely dependent on future authentication; if found to be a later 20th-century reproduction or a contemporary 'in the style of' piece, the value would likely decrease to the $150 - $300 range. To confirm the attribution, an in-person examination by a specialist is required to check for 'Berlingot' cane marks or faint etched signatures, evaluate the wear patterns on the base, and verify the consistency of the glass batch. Market demand for high-quality Art Deco glass remains stable, though buyers increasingly prioritize documented provenance and verified maker signatures.
