AI Appraisal Estimate

This item is a large goblet or water glass featuring a combination of decorative techniques on clear glass. The bowl of the glass exhibits a deep diamond-pattern cross-hatch cut on the lower half, which transitions into an etched or engraved floral and vine motif around the upper rim. The vessel sits upon a faceted, multi-knop stem that tapers down to a plain, circular foot. Its craftsmanship is stylistically consistent with late 20th-century lead crystal patterns from manufacturers such as Waterford or Mikasa, specifically those combining geometric cuts with delicate acid etching. The glass appears to have high clarity and light-refractive properties suggestive of lead crystal, though this would require physical testing to establish. There are no maker's marks, signatures, or acid-etched logos visible in the provided image; therefore, attribution to a specific manufacturer remains a hypothesis. The item appears to be in good vintage condition with no visible chips or cracks apparent from this angle. The exact dimensions cannot be determined from the image, but the proportions suggest a stately dining glass used for water or wine.

Based on my visual examination of the provided image, I have assessed this large goblet as a piece of high-quality lead crystal stemware, likely produced in the late 20th century. The glass features a sophisticated combination of deep-cut cross-hatch patterns and a delicate etched floral vine, a style reminiscent of makers such as Waterford or Mikasa. However, without a visible maker's mark or acid-etched signature—which I cannot verify from this photo—any specific attribution remains a hypothesis. The value is based on the assumption that this is a reputable lead crystal manufacturer; if the piece were determined to be a generic pressed-glass reproduction, the value would likely drop below $15. The estimate reflects current market interest in 'grandmillennial' aesthetics, though the market for single stems is generally softer than for complete sets. To provide a more precise valuation, I would need a physical inspection to confirm the presence of lead content via weight and ring-tone, as well as a magnifying search for microscopic etched logos on the base. The provided range assumes the item is in the good vintage condition described, as any chips to the faceted stem or rim would significantly diminish its secondary market appeal. Final confirmation of origin would require cross-referencing pattern books or obtaining provenance documentation.
