Cobalt Blue Glass Stemware, unverified maker

This piece features a striking two-tone or bi-color art glass composition, characterized by a deep cobalt blue bowl set atop a clear glass stem and circular foot. The bowl is shaped in a wide, dramatically flared, funnel-like silhouette reminiscent of a large cocktail glass or modernist centerpiece bowl. The clear stem displays a bulbous, molded shape with a tapering profile leading down to a flat, transparent base plate. The materials consist of colored and clear pressed or blown glass displaying typical light surface wear consistent with a secondhand or vintage retail environment, though no major chips, cracks, or structural repairs are immediately visible in the photograph. There are no visible maker's marks, stamps, or signatures apparent from this angle, and the identification rests purely on the visual characteristics of the glass color and form. The style suggests mid-to-late 20th-century decorative glassware production, potentially leaning toward contemporary art glass or decorative tableware, but without any physical hallmarks or documentation, its exact origin, manufacturer, and period remain unverified.

Based on what I can see in the photograph, this piece features a striking two-tone composition with a deep cobalt blue bowl and a clear glass stem and foot. I can note that the silhouette is wide and flared, while the stem has a bulbous, molded shape. However, I cannot verify from a photo alone the exact glass formulation, weight, exact period of manufacture, or whether any subtle maker's marks are present on the base. Because there are no visible signatures, stamps, or hallmarks apparent from this angle, the unverified maker attribution remains a working hypothesis. My value estimate of $40 to $80 reflects typical secondary market behavior for mid-to-late 20th-century decorative art glass stemware of this type, assuming the attribution is correct and the piece has no major hidden structural damage. General market demand for unbranded colored art glass tends to be modest, driven primarily by decorative appeal rather than collector-driven scarcity. To fully understand the piece and potentially establish a more precise valuation, I would need physical inspection to check for pontil marks, wear patterns, and subtle signatures, alongside potential consultation with a glass specialist. If physical examination reveals that the piece is a modern reproduction, a mass-market replica, or simply made in the style of mid-century modern glassware without the expected quality or vintage provenance, the value would likely decrease to the $15 to $30 range, resting purely on its functional and aesthetic merit as decorative tableware.
