AI Appraisal Estimate

This item is an elegant piece of stemware, specifically a wine glass featuring a clear glass bowl and a distinctively colored stem. The bowl is a standard tulip shape, designed for enhancing the aromatic qualities of wine, and appears thin-walled, suggesting it may be blown glass rather than thick molded glass. The most striking feature is the molded teal or aquamarine-colored stem, which exhibits a twisted, rope-like ribbed texture known as a spiral or spindle design. This stem transitions into a circular base of the same teal hue, which provides contrast against the clear upper portion. In terms of dimensions, the glass appears to be approximately 7-9 inches in height. The overall construction shows a seamless or near-seamless join between the clear bowl and the colored stem, indicating a good level of craftsmanship. There is no visible maker's mark or signature in the provided image, but the style is reminiscent of mid-to-late 20th-century glassware, possibly from the 1980s or 1990s when novelty colored stems were popular in home decor. The condition appears to be excellent with no visible chips, cracks, or clouding (etching) from hard water, though minor shelf wear on the bottom of the base is expected for a vintage item found in a secondary market setting. The clarity of the glass and the vibrant saturation of the teal pigment serve as quality indicators.

I have examined the digital representation of this teal spiral stem wine glass. The item exhibits characteristics typical of late 20th-century decorative stemware, likely produced between 1985 and 1995. The tulip-shaped bowl and machine-blown clarity suggest a mass-market production rather than artisanal studio glass. The 'rope' or 'spiral' molded stem in aquamarine is a classic vintage design element often seen in imports from Europe (like Luminarc) or domestic American tabletop brands. On-site visual inspection indicates the item is in excellent condition with no visible clouding or heat-stress fractures. The market for single pieces of novelty stemware is currently modest, with buyers primarily seeking replacements for broken sets. Valuation is based on comparable sales of unsigned 1980s colored stemware found in secondary markets and online vintage marketplaces. Rarity is low, as these were produced in large quantities for department store distribution. A primary limitation of this appraisal is the lack of a maker's mark or original foil label, which might slightly elevate the value if identified as a specific designer like Danforth or Gorham. To finalize authentication, I would require an in-person tactile examination to check for microscopic 'seeds' (bubbles) indicating glass quality, a UV light test to determine chemical composition of the pigment, and a physical inspection of the base for a pontil mark or acid-etched signature that may be invisible in photography.
