Etched Glass Goblet with Royal Cipher and Air Twist Stem

This item is an elegant clear glass wine goblet or chalice featuring a combination of sophisticated glassmaking techniques. The piece is constructed with three distinct parts: a rounded bowl, a decorative stem, and a flat circular foot. The bowl is intricately decorated with wheel-etched or copper-wheel engraved designs, most notably a prominent royal-style cipher or monogram topped with a crown and surrounded by scrolling foliate or floral accents. Below the rim, a decorative band of alternating floral or starburst patterns and oval 'lens' cuts provides a rhythmic border. The stem is a highlight of the craftsmanship, featuring a double-series air twist (opaque white or trapped air spirals) that winds vertically, characteristic of English or European glass techniques. In terms of condition, the glass appears to be in good vintage or antique state with high clarity, though minor surface scratches and base wear consistent with age and use may be present upon micro-inspection. This style is reminiscent of 18th-century English drinking glasses, though it may be a later 19th or early 20th-century high-quality revival piece or commemorative ware. The precise etching and complex stem design indicate a high level of artisanal skill.
