AI Appraisal Estimate

This listing includes a pair of art glass vases, likely hand-blown, given the organic shapes and embedded designs. The larger vase measures approximately 13.75 inches in height and 6.25 inches in diameter at its widest point. It is predominantly a rich cobalt blue color with applied or encased designs in shades of orange, brown, white, and possibly other darker colors creating a nature-inspired motif, possibly floral or abstract brushstrokes. The smaller vase is approximately 6.75 inches tall and 3.5 inches in diameter. It appears to be a deep aubergine or plum color, almost appearing black in certain lighting, with internal swirls and possibly an abstract white and red element within the glass near the top. Both vases have a slightly irregular, organic rim, indicating they are likely hand-finished. The surfaces appear smooth and without visible chips or cracks in the provided image, suggesting good overall condition. There are no discernible maker's marks, signatures, or stamps visible in the image. Based on the style and the information provided about their acquisition from a private gallery over 20 years ago, these vases likely date from the late 20th century or early 21st century. The quality of the glasswork appears good, with the colors vibrant and the embedded designs well-executed. The slight asymmetry of the shapes adds to their artistic appeal.

Upon examining the provided images and details, I have assessed this pair of hand-blown art glass vases. The larger cobalt blue vase (13.75" H) and the smaller aubergine vase (6.75" H) both exhibit characteristics of late 20th-century studio glass. The organic shapes, vibrant encased coloration, and hand-finished rims are indicative of skilled craftsmanship. Based on the visual evidence, both pieces appear to be in excellent condition with no visible chips or cracks. The primary factor limiting their value is the lack of a signature or maker's mark. Unsigned studio glass, regardless of quality, struggles to achieve the prices of pieces by known artists like Chihuly, Tagliapietra, or even lesser-known but signed studio artists. The market for unsigned decorative art glass is broad but generally commands more modest prices. Comparable unsigned hand-blown vases of similar size and quality typically sell in the secondary market for $100 to $300 per piece, depending on the venue and buyer interest. While aesthetically pleasing and well-made, their anonymity makes them more decorative than collectible. A definitive attribution would require physical examination for any faint etchings, pontil marks, or other identifying features not visible in photos. Without provenance or a signature, their value is based purely on their decorative and artistic merit.
