AI Appraisal Estimate

This is a vintage stemware piece crafted from clear glass, likely dating to the Art Deco period, approximately the 1920s-1940s. The vessel features a flared bowl with a V-shaped or conical profile typical of cocktail or sherbet glasses of the era. The bowl is decorated with a distinctive wheel-etched or cut pattern consisting of a horizontal band of circular dots (thumbprints) set between multiple horizontal rings, suggesting a mid-century or late Art Deco aesthetic. One of its most striking features is the triple-ball or 'knob' stem, which consists of three stacked spherical glass elements that provide a sculptural and tactile quality. This style of stem was frequently used by American glass manufacturers like Heisey, Fostoria, or Cambridge, although no specific maker's mark is visible. The glass appears to have good clarity with light reflecting sharply off the etched surfaces. The base is a simple flat circular foot that provides stability to the elegant, vertically focused design. Regarding condition, the piece appears to be in good vintage state with no apparent cracks or major chips visible in the photograph, though fine surface scratches (wear) consistent with age and use may be present on the base. The thickness of the glass suggests it was intended for regular household use rather than purely ornamental display.

Based on my visual examination of this Art Deco era stemware, I have identified it as a clear glass champagne/sherbet coupe featuring a distinctive triple-ball or 'knob' stem and wheel-etched thumbprint-and-ring ornamentation. The design is highly characteristic of American 'Elegant Glass' manufacturers such as Fostoria, Cambridge, or Morgantown, dating roughly from 1925 to 1945. The clarity of the glass suggests a quality lead or lime glass composition, and the etched pattern displays the precision typical of mid-century machine or hand-guided wheel cutting. Condition appears good, with no visible clouding or significant 'sickness,' though the base likely shows minor shelf wear consistent with its age. This style currently faces a moderately soft market; while Art Deco remains popular for home bar styling, mass-produced elegant glassware from this era is plentiful. Comparables for single stems typically fall in the $15-$25 range at retail, though a complete set of 8 or 12 would command a premium. The triple-ball stem is a desirable feature that increases tactile appeal for collectors. I must note that definitive identification of the manufacturer is limited without a visible acid-etched maker's mark or specific measurement references to match against historical catalogs. A physical inspection is required to check for 'flea bites' along the rim and base that are invisible in photos. Furthermore, a blacklight test would be necessary to check for manganese or uranium content, which can sometimes influence price among specialized glassware collectors.
