AI Appraisal Estimate

This is a substantial hand-blown art glass vase, measuring approximately 12 to 13 inches in height. The piece is crafted from a transparent apple green glass featuring an internal white swirl or 'latticino' style decoration that spirals diagonally around the body. The form is characterized by a wide, flared rim that tapers into a short neck, which then expands into a bulbous shoulder before narrowing down to a weighted base. A notable manufacturing feature is the presence of a rough, unpolished pontil scar on the bottom, indicating traditional off-hand glassblowing techniques rather than mold-pressed production. There are no visible maker's marks, signatures, or labels. The glass contains small seeded bubbles and minor striations consistent with artisan craftsmanship. While the style evokes Mid-Century Modern aesthetics, particularly Italian or American studio glass from the late 20th century, the lack of a polished pontil often suggests a more contemporary or utilitarian studio origin. The condition appears excellent with no visible chips or cracks, though the rough pontil remains as a sharp, unrefined element of its original construction.

I have examined the images and descriptions of this 12-13 inch hand-blown apple green swirl art glass vase. The piece exhibits characteristic traits of late 20th-century studio production. The presence of a rough, unpolished pontil scar is a critical diagnostic feature; while it confirms the piece was hand-blown, the lack of a ground and polished 'button' or a signature generally indicates a mid-market decorative item rather than a work by a high-end atelier like Murano's Venini or a recognized American studio artist. The 'latticino' style swirl and vibrant apple green color are hallmarks of the Mid-Century Modern revival style, which remains popular for interior design. The condition appears commensurate with careful display, with the seeded bubbles and striations being inherent to the artisanal process rather than defects. Current market demand for unsigned art glass of this scale is steady but capped by the lack of attribution. Comparable sales for similar unsigned 'rough pontil' vases in this size range consistently fall within the $45 to $75 bracket at auction. Without a signature or original label, the piece is valued primarily on its aesthetic and decorative merit. Please note that this appraisal is based on photographic evidence and descriptions. A definitive valuation would require an in-person inspection to verify the glass's weight, ultraviolet fluorescence (to check for specific chemical compositions of older glass), and a closer look for micro-signatures or acid-etched marks that may not be visible in photos. Provenance, such as original purchase receipts from a specific studio, would be necessary to elevate this valuation into a higher 'fine art' category.
