AI Appraisal Estimate

This item is a clear glass vessel with a flared rim and a stemmed base, stylistically consistent with late 20th-century pressed or cut glass patterns. The body features vertical linear fluting that transitions into a mid-section band of diamond-shaped geometric cuts, followed by a lower section of vertical panels. The stem is relatively short and fluted, leading to a circular, footed base with radiating rayed patterns on the underside. The glass appears to be clear and colorless, though the weight and lead content cannot be determined from the image. No maker's marks or signatures are visible on the exterior surfaces shown, making a definitive attribution to a specific manufacturer like Waterford or Mikasa impossible without physical inspection of the base for an etched mark. The item shows no obvious chips or cracks in the photo, appearing in good condition. The design is reminiscent of 'Lismore' or similar traditional patterns often found in crystal giftware from the mid-to-late 20th century. Hedged language is used because glass patterns are frequently replicated across different manufacturers and price points.

Based on my visual analysis of the provided image, this vessel features a combination of vertical fluting and geometric diamond cuts consistent with traditional patterns such as 'Lismore.' The piece appears to be in good condition without visible structural damage. However, from a photograph alone, I cannot verify the lead content, weight, or the presence of a faint acid-etched maker's mark, which are essential for distinguishing high-end lead crystal from common pressed glass. While the design is in the style of manufacturers like Waterford, I must treat any specific attribution as a hypothesis. My value estimate of $25.00 to $65.00 reflects the typical secondary market range for a single stem of this type, assuming it is a recognized crystal brand. If a physical inspection were to reveal a brand signature, the item would likely sit at the higher end of that range. Conversely, if the piece is an unattributed glass reproduction or shows signs of machine-pressed seams not visible here, the value would typically decrease to $10.00–$15.00. The market for mid-to-late 20th-century glassware remains stable but relies heavily on brand recognition and the 'ring' of quality crystal. To establish a more precise value, an in-person examination is required to check for hallmarks on the base and to assess the clarity and refractive index of the material. This report does not assert authenticity, and the estimate is contingent upon the item being a genuine lead crystal piece from a reputable glassware manufacturer.
