AI Appraisal Estimate

This is a hand-cut crystal tumbler, likely a double old fashioned (DOF) glass, featuring a classic Bohemian or European 'Pinwheel' or 'Star' pattern. The glass is crafted from high-quality clear lead crystal, evidenced by the sharp refraction of light through the deep wedge cuts. The central decorative motif consists of a multi-pointed starburst or pinwheel surrounded by fine cross-hatching and vertical fan cuts that extend toward the rim. The base appears thick and weighted, a characteristic of premium barware designed for stability and feel. In terms of condition, the glass shows good clarity without obvious clouding or 'sick glass' syndrome, though minor shelf wear on the bottom and tiny flea bites on the sharp edges of the cut patterns are common for pieces of this age. This style was highly popular in the mid-to-late 20th century, particularly from makers in West Germany, Poland, or the Czech Republic (such as Nachtmann or Pinwheel Crystal). The craftsmanship is evident in the precision of the geometric cuts and the overall brilliance of the material.

Based on my visual examination of this lead crystal double old fashioned glass, I find it to be a classic example of 20th-century European cut glass, likely originating from Polish or Czech workshops. The 'Pinwheel' or 'Star' pattern is a traditional motif synonymous with Bohemian craftsmanship. My inspection reveals high brilliance and sharp light refraction, indicating a high lead content. The cuts appear deep and precise, though I noted minor 'flea bites' on the sharpest facets, which are typical for used barware but slightly detract from a 'mint' valuation. The market for this specific pattern is currently saturated due to its immense popularity between 1960 and 1980. While the quality of the weight and cut is objectively high, these pieces were mass-produced for the export market. Similar individual tumblers regularly sell on the secondary market (e.g., eBay, Etsy) for $15 to $25. Retail replacement value or 'set' pricing typically sees a slight premium. Limitations: Verification of authenticity and quality is limited by the digital format. For a definitive valuation, I would need to perform a physical 'ring test' to check for the sustained resonance unique to high-quality lead crystal. I would also inspect for acid-etched maker’s marks (such as Nachtmann or Waterford) which are often invisible in photographs. Without a signature or original provenance documentation (e.g., original stickers or boxes), this must be valued as 'unattributed Bohemian crystal.' Scientific testing via X-ray fluorescence could confirm the exact lead percentage, though the cost of such testing would exceed the item's market value.
