Waterford Crystal Lismore Pattern Replacement Glass Stopper

This item is a replacement decanter stopper crafted from high-quality lead crystal, featuring the iconic 'Lismore' pattern characterized by its signature diamond and wedge cuts. The stopper has a classic conical or 'tear drop' shape with a pointed apex, tapering down to a ground glass plug base designed to create an airtight seal with a decanter neck. The crystal exhibits excellent clarity and high refractive properties, typical of high-end glass manufacturing. The cutting is precise, showing deep, crisp facets that catch the light efficiently. In terms of condition, the visible crystal portion appears to be in excellent state with no obvious chips or 'fleabites' to the sharp edges of the cuts. The ground glass frosted neck shows typical signs of use but remains intact. Measuring approximately 3 to 4 inches in total height, this piece is likely from the mid-to-late 20th century. While specific acid-etched signatures are not clearly visible in the photo, the pattern is unmistakably associated with Waterford Crystal of Ireland, known for exceptional craftsmanship and traditional style.

I have examined the digital images of this lead crystal replacement stopper featuring the iconic Waterford 'Lismore' pattern. Based on my visual inspection, the piece exhibits the characteristic deep wedge and diamond cuts associated with Waterford’s craftsmanship. The clarity and refractive quality appear consistent with high-lead-content crystal. The condition of the decorative head is excellent, showing no visible chips to the sharp mitered edges, while the ground neck displays normal superficial wear required for a functional seal. The Lismore pattern is one of the most widely produced and recognized crystal patterns globally, which ensures a steady secondary market for replacement parts. Current market trends for original Waterford components fluctuate based on the specific decanter model they fit (e.g., ships decanter vs. standard spirit bottle). Comparables from recent auction and specialty replacement sites typically range between $50 and $90. The primary value driver is the integrity of the cut edges; any small 'flea bites' would reduce the value by 50%. Limitations of this digital appraisal include the inability to verify the acid-etched ‘Waterford’ mark usually found on the base or side of the plug, which is often faint. I cannot confirm the exact fit without physical calipers or testing against a corresponding decanter neck. To fully authenticate this item, an in-person inspection under UV light (to check for the characteristic green/yellow fluorescence of vintage lead crystal) and a search for the signature would be necessary. This valuation assumes the item is an authentic Irish-made or early European-production piece rather than a later mass-market derivative.
