Art glass vase with aventurine inclusions

This is a decorative art glass vase featuring a flared, ruffled rim and an elongated, tapering body. The exterior showcases a vibrant color palette combining shades of chartreuse or lime green, interspersed with dark, nearly black mottled spots or inclusions, and metallic copper-colored patches that resemble aventurine or copper foil flecks embedded within the glass layers. The surface is smooth and glossy, reflecting light brightly, particularly along a central vertical glare line from the photography. The vase appears to be housed within a cardboard shipping container lined with inflated protective packing plastic on either side. Regarding the physical dimensions and condition, the vase appears largely intact with no obvious cracks or major structural damage visible from this top-down packaging angle, though a thorough physical inspection is not possible from the photograph alone. The owner provides unverified context describing the piece as a twelve-inch vase with aventurine flecks. There are no clearly visible maker's marks, signatures, or stamps discernible in the provided image, so the identification remains strictly descriptive based on visual characteristics consistent with contemporary or mid-to-late 20th-century decorative art glass production methods. The aesthetic quality suggests studio or factory art glass traditions, but without hallmarks or stamps, any specific maker attribution is unverified.

Based on what I can see in the provided image, this is a 12-inch decorative art glass vase featuring a flared, ruffled rim and an elongated body with chartreuse green coloration and metallic copper-colored aventurine inclusions. Per user submission, the piece is identified as a 12-inch vase with aventurine flecks. I can't verify from a photo whether the aventurine inclusions are genuine metal foil or how the interior glass layers are constructed, and I would need physical inspection to confirm the weight, maker's marks, and exact manufacturing techniques. The estimated value range of $300 to $500 assumes the owner's claims and stylistic attributions to mid-to-late 20th-century studio or factory art glass production are correct. General market demand for decorative art glass of this aesthetic remains steady among collectors of mid-century and contemporary studio pieces, though values heavily depend on pristine condition and recognizable craftsmanship. If a physical inspection reveals that the vase is a later reproduction, a mass-market replica, or simply made in the style of mid-century art glass without the attributed pedigree, the value would likely decrease significantly to the $75-$150 range. To establish authenticity, market value, and specific attribution more firmly, an in-person examination by a qualified art glass specialist, search for elusive maker's marks, and potential provenance documentation would be required.
