Steuben Crystal Glass Cup Appraisal

Steuben Crystal Glass Cup (presumably a tumbler or highball)

The item depicted is a clear crystal glass, specifically identified as a potential Steuben glass cup due to additional context. The glass is transparent and appears to be made of high-quality, lead-free crystal, characteristic of Steuben's craftsmanship. The design is elegantly simple, featuring a smooth, flaring rim that gently tapers down to a substantial, solid base. The interior of the glass shows concentric rings leading down to a convex center, which is typical for drinkware designed to be stable and aesthetically pleasing. A notable feature is a subtle etching or signature visible near the rim on the interior side, which, per the context provided, is a 'Steuben' signature. This etching confirms the manufacturer and indicates its authenticity as a genuine Steuben piece. The overall construction suggests a hand-blown or highly finished machine-made process due to its clarity and lack of visible seams, a hallmark of quality glasswork. There are no immediate signs of significant damage such as chips, cracks, or heavy scratching visible from this angle. The surface appears polished and clean, retaining its original luster, suggesting good care or minimal use. The visible reflection and refractive qualities point to a high lead content or a very pure, high-density glass composition, contributing to its brilliance. Given the context of a collection of 8 large and 18 small cups, all signed and with bags, these pieces likely date from the mid-20th century onwards, aligning with Steuben's period of producing such elegant barware and stemware. The presence of original bags further enhances their collectibility and suggests they have been well-preserved. The craftsmanship is evident in the uniform thickness and the smooth transitions of the glass, indicating a high level of skill in its production.
