green glass vase in the mid-century swirl style

This is a decorative green glass vase featuring a distinct swirled or twisted optical effect running vertically through the body. The piece is crafted from a vibrant emerald or forest green translucent glass material, showing a bulbous base that tapers into a slender, hourglass-style neck before flaring slightly outward at the top rim. The overall silhouette is organic and fluid, showcasing physical characteristics consistent with mid-20th-century molded or blown art glass production techniques. Based entirely on visual inspection of the provided photograph, there are no visible maker's marks, signatures, or labels present on the exterior surface; therefore, the identification relies strictly on stylistic features. The vase appears to be in overall fair visual condition with smooth, reflective surfaces, though minor surface wear, dust, or microscopic scuffs cannot be ruled out without a thorough physical examination. The rich color and dynamic twisting pattern suggest a level of decorative craftsmanship typical of vintage European or American decorative glassware from the mid-century era, though any specific attribution remains speculative and subject to in-person expert verification.

Based on what I can see in the photograph, this decorative green glass vase exhibits a striking mid-century swirl style, characterized by its vibrant translucent green hue, bulbous base, slender hourglass neck, and flared rim. The optical twisted effect points toward mid-20th-century European or American art glass production techniques. However, I can't verify from a photo whether the piece is an original vintage production or a later decorative reproduction, as I see no visible maker's marks, signatures, or labels on the exterior surface. I would need physical inspection to confirm the glass composition, weight, pontil mark characteristics, and overall wear patterns. The estimated value range of $150 to $300 assumes that the attribution to the mid-century era is correct; however, the value depends heavily on authentication. An unauthenticated piece of this type, or one determined to be a modern reproduction made 'in the style of' rather than an authentic period piece, would typically sell for a lower range, closer to $40 to $80. General market demand for mid-century colored glassware remains steady among interior decorators and collectors of vintage decor, supporting this price tier for visually appealing display pieces. To more precisely determine authenticity and value, an in-person examination by a qualified glassware specialist, combined with detailed provenance documentation and expert appraisal, would be necessary.
