AI Appraisal Estimate

This item is a vintage Murano-style green uranium glass vase. The vase has an organic, almost free-form shape with a ruffled or undulating rim. The body of the vase is a deep, somewhat iridescent blue-purple under normal light, with a distinct bright green color that fluoresces vibrantly under UV light. The green color is concentrated along the rim and also appears within the body of the glass. The base is a solidified pedestal-like structure tapering from the body. The glass appears thick, suggesting a hand-blown or hand-formed process. The overall condition is unclear from the image regarding chips or cracks, but the glass appears clear and bright suggesting relatively good condition. The style is consistent with mid-20th century Murano glass or pieces inspired by the Murano technique. The presence of uranium indicates production likely between the late 19th century and the mid-20th century, though it was sometimes used after that period. This piece is notable for its color-changing properties under UV light.

Based on my visual examination of the provided images, this Murano-style vase presents as a compelling mid-20th-century decorative art piece. The bi-color effect, with a blue-purple body and a distinct, vibrant green fluorescence under UV light, is a strong indicator of uranium glass, a material popular during that era. The hand-formed, organic shape with its ruffled rim is characteristic of the Murano style, although without maker's marks, signatures, or pontil mark analysis, I cannot definitively attribute it to a specific Murano factory. Its dimensions of 3.5x7.25 inches make it a desirable size for collectors. The market for uranium glass and mid-century art glass remains steady, with collectors particularly drawn to unique forms and dramatic color-changing properties like this one possesses. Similar unsigned, hand-blown uranium glass vases of this style and period typically sell in the $75 to $150 range. The value of this specific piece is predicated on its excellent presumed condition and strong visual appeal. However, this appraisal is limited by the inability to conduct a physical inspection. A full authentication would require examining the piece for any signatures or labels, studying the pontil mark on the base to identify manufacturing techniques, and assessing the condition for any subtle chips, cracks, or 'sick glass' that are not visible in the images.
