AI Appraisal Estimate

This item is a cylindrical glass vase crafted in a deep cobalt blue translucent glass. The form is characterized by five distinct horizontal raised rings or ribs that wrap around the circumference of the vessel, creating a stacked or 'beehive' profile. The glass appears thick-walled with a polished rim and a stable, flat base. In terms of condition, there are visible surface scuffs and minor abrasions consistent with shelf wear and previous use, though no major chips or structural cracks are immediately apparent in the photograph. The craftsmanship is consistent with mid-20th-century Scandinavian or Italian art glass traditions, potentially echoing designs by makers such as Riihimäki (Riihimäen Lasi) or similar European glassworks from the 1960s or 1970s. Because no stickers, maker's marks, or etched signatures are visible on the exterior or through the glass in this image, this attribution remains a hypothesis based strictly on its modernist aesthetic and color profile. Physical inspection of the pontil mark or base wear would be necessary to further narrow its origin.

Based on my visual analysis of the provided image, this cobalt blue glass vase exhibits a ribbed cylindrical form characteristic of mid-century European decorative glass. I can see a rich color profile and structural features that suggest a potential connection to 1960s-70s Scandinavian makers, such as Riihimäen Lasi, though I cannot verify this from a photo alone. Without a visible maker's mark or signature, this attribution remains a hypothesis. The value I have assigned is for a piece of this type assuming it is a vintage production from a recognized glassworks of that era. I can see surface abrasions and scuffs which indicate shelf wear; such condition issues generally exert downward pressure on market value. This estimate reflects the current stable demand for mid-century modern 'pop of color' glassware in the secondary market. To confirm a specific maker, an in-person physical inspection is required to examine the base for a pontil mark or specific wear patterns. If this item were later determined to be a modern mass-produced reproduction or a contemporary piece 'in the style of' the mid-century period, its value would likely fall to the $15.00 to $25.00 range. Establishing a higher valuation would rely on finding documentation of its origin or a verified designer mark during a hands-on examination.
