Art glass vase with aventurine inclusions

This is a hand-blown art glass vase featuring a vibrant, multicolored decorative pattern. The physical characteristics include a prominent yellow background base glass heavily overlaid with vertical pulled streaks and spots of dark brown or black, interspersed with shimmering copper-colored aventurine flecks that catch the light. The form is a wide, tapering cylindrical body with a gently flared, undulating or ruffled rim. The construction exhibits characteristics typical of studio art glass craftsmanship, displaying smooth surface transitions and an integrated aesthetic common in mid-century or contemporary decorative glassware. Regarding notable features, there are no visible maker's marks, signatures, or stamps directly readable in the provided image. The visual identification is based entirely on the distinctive color palette, glass technique, and form rather than any stamped attribution. The overall condition appears well-preserved with a glossy finish and no obvious major structural damage or repairs visible from this angle, though the base and pontil area are not visible in this specific photograph. The owner supplies additional unverified context describing the piece as a 12-inch-tall vase featuring aventurine copper flecks and a smooth pontil, though these specific measurements and base details cannot be independently verified from the visual evidence provided alone. The style is consistent with mid-century modern or contemporary studio art glass production utilizing traditional Venetian-inspired aventurine glass techniques.

Based on what I can see in the photograph, this hand-blown art glass vase exhibits a vibrant yellow background, vertical pulled streaks of dark brown, and shimmering copper aventurine flecks, all topped with a ruffled rim. The owner describes the piece as a 12-inch-tall vase with aventurine copper flecks and a smooth pontil. Per user submission, this piece is associated with mid-century studio art glass techniques, though I cannot independently verify the exact height, weight, dimensions, base details, or presence of a smooth pontil from a two-dimensional image alone. My estimate of $300-$500 assumes that the owner's claims regarding dimensions, material composition, and the presence of aventurine glass are correct upon physical inspection. The market for mid-century modern and contemporary studio art glass with aventurine inclusions remains steady among decorative arts collectors, though values fluctuate based on exact craftsmanship, condition, and attribution. I can't verify the exact maker, studio, or production date from a photo, and would need physical inspection to confirm the quality of the glasswork, look for hidden signatures or marks, and evaluate the base. If physical inspection reveals the item is a modern reproduction, replica, or made 'in the style of' rather than an authentic period piece, the value would likely drop significantly to the $75-$150 range. To establish a more precise valuation and confirm authenticity, one would need in-person examination by a qualified glass expert and verification of any maker's marks or provenance documentation.
