AI Appraisal Estimate

This item is a single wine goblet featuring a deep emerald green bowl joined to a clear, transparent glass stem and circular foot. The bowl is tulip-shaped with a slightly flared rim, characteristic of Mid-Century Modern or late 20th-century glassware styles. The construction appears to be machine-made or semi-automatic pressed glass, given the uniformity of the bowl and the crisp transition at the stem junction. The green glass exhibits a rich, forest-tone saturation that suggests the use of chromium or copper oxides in the glass melt. The stem is faceted or multi-sided, providing a geometric contrast to the smooth curves of the bowl, and terminates in a flat, plain circular base. In terms of condition, the glass shows high clarity with no immediate signs of chips, cracks, or heavy clouding from dishwasher use. There are minor surface reflections but the luster remains strong. While no specific maker’s mark is visible in the provided image, the silhouette is reminiscent of mid-to-high level department store glassware from the 1970s through the 1990s, such as pieces produced by Mikasa, Noritake, or Libbey. The scale appears standard for a red wine glass, likely standing 7 to 8 inches in height.

I have virtually examined this emerald green cased wine goblet. The item presents in excellent vintage condition; the forest-green bowl retains a vibrant saturation and strong luster, while the clear faceted stem and foot show no evidence of ethical 'sick glass' or clouding common in pieces subjected to harsh detergents. The construction—notably the crisp transition between the bowl and the multi-sided stem—indicates a high-quality, semi-automatic production likely dating from the 1970s to the 1990s. While the design is reminiscent of patterns by manufacturers like Mikasa or Noritake, the absence of a visible acid-etched mark suggests it may be a high-end department store private label. The market for single replacement stems remains steady but modest. Collectors typically seek these for 'fill-in' pieces for existing sets rather than as stand-alone investments. The emerald-and-clear contrast is aesthetically desirable for holiday tablescapes, though the item is not considered rare. Comparable sales for similar mid-to-late 20th-century glassware typically fall in the $15–$25 range per stem. Significantly, this appraisal is based on visual data alone. For a conclusive authentication, a physical inspection is required to check for 'shear marks' on the base, pontil scars, or micro-chips at the rim. I would also need to verify the resonance of the glass to determine lead-crystal content versus soda-lime glass, as the former would favor the higher end of the valuation range. Definitive provenance or original packaging would also be necessary to confirm the specific manufacturer and designer.
