AI Appraisal Estimate

This is a large, hand-blown art glass vase featuring a flared rim, a tapered neck, and a bulbous body that narrows toward the base. The glass is a consistent pale, translucent celadon-green color throughout. The primary decorative feature is an internal white swirl or 'latticino' style threading that wraps diagonally around the circumference of the vessel, creating a subtle textured appearance and visual movement. Small air bubbles, known as seeds, are occasionally visible within the glass matrix, which is a characteristic of the hand-blowing process rather than a defect. The rim is broad and flat-ground, showing quality finishing. No prominent maker's marks or signatures are visible in the provided image. The overall condition appears excellent with no visible chips, cracks, or heavy surface scratching; however, minor shelf wear on the bottom would be expected for an item of this type. The style is reminiscent of Mid-Century Modern or contemporary studio glass, likely dating from the late 20th century to the present. The craftsmanship is evident in the symmetrical proportions and the even distribution of the decorative swirls.

I have carefully examined the provided images of this Large Pale Green Swirl Art Glass Vase. The piece exhibits high-quality hand-blown characteristics, including characteristic 'seed' bubbles and a precisely ground rim, suggesting studio-level production rather than mass-market manufacture. The celadon hue and internal white spiraling—reminiscent of Italian 'mezza filigrana' techniques—indicate a high degree of technical skill. The condition appears to be 'Fine to Excellent,' with no structural degradation or significant surface abrasions observed. The current market for unsigned studio glass remains stable but selective. Pieces of this scale and aesthetic appeal are highly sought after by Mid-Century Modern enthusiasts for interior design purposes. Comparables for unsigned, late 20th-century studio glass of this size typically realize between $100 and $250 at auction. The value is buoyed by the elegant proportions but capped by the lack of a verifiable maker’s mark or signature (such as Venini or a known American glass artist), which would otherwise significantly multiply the valuation. Limitation Statement: This appraisal is based solely on digital images and descriptive text. A physical inspection is necessary to verify the base's wear patterns, check for 'flea bites' at the rim, and confirm whether any faint acid-etched signatures were missed. For full authentication and to potentially increase the valuation, research into provenance (original gallery receipts) or an in-person examination by a specialist in Italian or Murano-style glass is recommended.
