AI Appraisal Estimate

This item is a tall highball or tumbler glass crafted from heavy, high-quality lead crystal, showcasing the iconic 'Lismore' pattern commonly associated with Waterford Crystal. The glass features a classic cylindrical form with a slight taper toward the base. The decorative program is divided into distinct sections: the upper third of the glass is left clear and polished, while the lower two-thirds are heavily ornamented with deep wedge cuts. The central design consists of alternating long and short vertical 'leaf' or 'diamond' cuts, topped by intricate multi-pointed starburst or 'rosette' motifs. Below these, a band of traditional diamond cross-hatching adds depth and refractive brilliance. The base appears thick and stable, characteristic of mid-20th-century luxury glassware. The material exhibits high clarity and a bright, silvery luster typical of leaded crystal. No major chips or cracks are immediately visible, though minor surface scratches (shelf wear) on the bottom are common for an item of this age. The craftsmanship suggests a high level of skill in hand-cutting, with sharp, precise edges that catch and play with the light. This style reached peak popularity in the mid-to-late 20th century.

Based on my visual examination of the provided description and image, I have identified this as a Highball Glass in the 'Lismore' pattern by Waterford Crystal. First introduced in 1952, Lismore is the most recognized and sought-after pattern in the history of lead crystal. The glass displays the signature wedge and diamond cuts that distinguish this line. Condition appears to be Excellent; the clarity of the lead crystal is high, suggesting it has been well-maintained without the cloudy 'sickness' often found in machine-washed glass. Market demand remains stable due to the pattern's popularity for replacement services and wedding registries. While individual highball glasses are not rare, they hold their secondary market value better than newer, lighter crystal brands. Factors impacting value include the presence of the etched 'Waterford' acid mark on the foot and the absence of 'flea bites' or rim chips. Limitation Note: This appraisal is based on photographic evidence alone. Without a physical inspection, I cannot confirm the presence of an authentic acid-etched signature or verify the tactile 'ring' (resonance) associated with high lead content. A full authentication would require an in-person examination to check for microscopic 'seeds' (bubbles) in the glass, verify the weight, and document any provenance. Scientific testing is generally not required for this caliber of crystal unless pieces are suspected to be contemporary imitations with lower lead content.
