Modernist-style spiral cut glass bud vase

This appears to be a tall, slender glass bud vase characterized by a cylindrical form with a thick, weighted base. The most prominent feature is a continuous, carved spiral groove that wraps around the exterior of the clear glass body from near the base to just below the rim. Stylistically, the piece is consistent with modernist or contemporary studio glass, possibly dating from the late 20th century to the present. The glass appears to be of high clarity, which may indicate lead crystal or high-quality soda-lime glass, though this cannot be confirmed without physical testing for resonance and weight. There are no visible maker's marks, signatures, or acid-etched stamps apparent in the image, making a specific brand attribution a hypothesis only. In the absence of branding, the design is stylistically consistent with works by manufacturers such as Orrefors or Kosta Boda, but it remains an unverified attribution. The vase appears to be in good condition with no visible chips or cracks along the carved edges. It is currently filled with water, which demonstrates its functionality and the refractive properties of the thick glass walls. The rim appears flat and polished, suggesting professional finishing techniques synonymous with mid-to-high-tier glassware.

Based on what I can see, this is a modernist-style spiral cut glass bud vase featuring a weighted base and a continuous carved groove. The piece displays clarity consistent with high-grade soda-lime glass or lead crystal, though I cannot verify resonance or density from a photo. I have observed no visible signatures or acid-etched marks, so any attribution to specific manufacturers like Orrefors or Kosta Boda remains a working hypothesis rather than an established fact. The value estimate is Based on the assumption that this is a quality piece of contemporary studio or designer glass in good condition. If it were found to bear a mark from a highly sought-after Swedish glassworks, the value could sit at the higher end of the range. However, if it is a mass-produced piece 'in the style of' those makers without a pedigree, the value would likely drop to $15–$25. General market demand for modernist glassware remains steady, yet prices are heavily dictated by brand recognition. A physical inspection is required to check for 'flea bites' along the spiral edges and to confirm the quality of the glass through light refraction. To reach a more certain valuation, I would need to perform a tactile examination for weight and surface wear, and I would recommend researching archival catalogs to see if this specific pattern matches known designer silhouettes. Without provenance or a verifiable mark, the piece must be valued as an attractive, well-crafted decorative object of indeterminate origin.
