Cobalt Blue Glass Stemware with Nautical Etching

This item is a stemmed footed goblet or water glass featuring a deep cobalt blue bowl and a clear glass stem and base. The bowl is decorated with white etched or frosted nautical imagery, including a lighthouse and an anchor entwined with a rope border. The stem has a molded, ribbed, or 'baluster' shape, providing a decorative transition to the flat, circular clear base. Based on the deep blue color and the specific motif, the design is stylistically consistent with 20th-century American decorative glassware, possibly in the manner of Libbey or similar mid-century manufacturers. No visible maker's marks or signatures are present on the foot or bowl in the photograph to provide a brand attribution. The glass appears to be in good used condition with some minor surface dust and smudging visible. The etching shows clear detail, and there are no obvious chips or cracks visible in the provided image. The attribution remains a hypothesis based on aesthetic features and common nautical-themed glassware patterns produced between the 1950s and 1990s.

I have examined the image provided of the cobalt blue glass stemware with nautical etching. Based on what I can see, the glass appears to be a mid-to-late 20th-century decorative piece. The deep cobalt bowl and baluster stem are stylistically consistent with American glassware manufacturers like Libbey or similar secondary producers, though without a physical inspection or visible maker's mark, I cannot verify the specific manufacturer or production date from a photo alone. The value is estimated for a single stem as part of a set; should this be a single orphaned glass, the value would typically sit at the lower end of the range. General market demand for nautical-themed mid-century glassware remains stable among collectors of maritime decor and vintage hosting supplies. The estimate assumes the glass is in good condition without chips or interior clouding, which cannot always be detected in photographs. To confirm a specific attribution, I would need an in-person examination to check for ground pontil marks, manufacturer stickers, or acid-etched signatures on the base. If these were determined to be modern mass-market reproductions or contemporary 'in the style of' pieces from a discount retailer, the value would likely drop to $5-$10 per item. The final value depends on the confirmed manufacturer and quantity available, as a complete set of six or eight would command a higher per-item premium in the secondary market.
