Art glass bird figurine in the Murano style

This item is an avian-themed art glass sculpture featuring a stylized bird perched upon a swirling base. The piece is characterized by a sophisticated use of the 'sommerso' technique, layering transparent blue and yellow glass within a clear exterior. The body of the bird displays a gradient of vibrant turquoise blue transitioning into a golden yellow hue. The base and crest appear to incorporate 'avventurina' or gold-foil inclusions, resulting in a shimmering, metallic golden interior effect. The sculpture is formed with fluid, organic lines, standing on a heavy clear glass base with a rounded triangular footprint. A noteworthy feature is the bird's crest, which is fashioned from clear glass with gold-speckled highlights. The user has provided context attributing this piece to Murano origin; however, as no maker's mark, signature, or original labels are visible in the provided image, this attribution remains a hypothesis and is subject to in-person expert verification. The craftsmanship is consistent with mid-to-late 20th-century Venetian glassmaking traditions. The condition appears well-preserved with no visible chips or cracks from this angle, though the surface shows typical reflections. The identification is based solely on stylistic elements common to Italian art glass without physical confirmation of provenance.

I have examined the digital image of the avian art glass sculpture. The piece exhibits the fluid lines and complex 'sommerso' and 'avventurina' techniques characteristic of 20th-century Venetian craftsmanship. The owner identifies this as Murano glass; however, based on what I can see, there are no visible signatures or labels to support this hypothesis. While the quality suggests an Italian origin, I cannot verify the specific factory or artist from a photo alone. A physical inspection would be required to look for micro-scratches on the base or specific tool marks that might confirm a maker like Seguso or Archimede Seguso. The estimated value of $150-$350 assumes the attribution to a Murano furnace is correct and that the piece is in excellent condition. This range reflects general market demand for mid-century Italian decorative glass. If a physical examination were to identify a specific master glassblower, the value could increase significantly. Conversely, if the piece is determined to be a contemporary 'in the style of' reproduction or an unattributed mass-produced copy, the value would likely drop to $40-$75. To reach a more formal conclusion, I would need to see provenance documentation or have the piece inspected by a specialist in Venetian glass to verify the material composition and specific manufacturing traits.
