Art glass vase with aventurine flecks

This is a decorative art glass vase featuring a dynamic and colorful visual pattern. The piece exhibits a flared, undulating or ruffled rim and tapers down toward a narrower base, nestled inside a protective cardboard and plastic shipping environment. The body of the glass displays a complex mottled and striated mix of colors, predominantly lime green, chartreuse, and deep black spots or feathering, punctuated by prominent metallic copper-colored aventurine flecks that catch the light with a glittering effect. The owner has provided context noting that the vessel stands approximately 12 inches tall and incorporates aventurine flecks, though this user-supplied information remains unauthenticated and requires physical inspection for full verification. No maker's marks, signatures, or studio stamps are visible in the provided photograph; therefore, the identification relies strictly on the visible physical characteristics such as the multi-colored glass composition, metallic inclusions, and free-blown form. The item appears to be in generally good visual condition as presented in the packaging, showing smooth reflective surfaces without any obvious structural cracks, chips, or major surface damage visible from this single vantage point. The aesthetic style points toward mid-to-late 20th century or contemporary studio art glass production, reflecting techniques commonly associated with Italian Murano-style glasswork or contemporary decorative art glass manufacturing, though without direct examination of the base or acid stamps, any specific attribution or era remains a stylistic estimation rather than a fact.

Based on what I can see in the photograph, this decorative art glass vase displays a vibrant mottled coloration in lime green, chartreuse, and black, enhanced by metallic copper-colored aventurine flecks and a flared, ruffled rim. Per user submission: the vessel stands approximately 12 inches tall and incorporates aventurine flecks, though I can't verify these precise dimensions or the internal composition from a photo alone. No maker's marks or studio stamps are visible from this single vantage point, so the current assessment is treated as a working hypothesis dependent on physical inspection. My value estimate of $300-$500 assumes the piece is a quality mid-to-late 20th century studio art glass production, such as Italian Murano-style work. General market demand for colorful, decorative studio art glass remains steady among interior decorators and collectors of mid-century design, though pieces lacking a clear signature or documentation typically trade at a more modest level. If physical inspection reveals the item to be a modern reproduction, replica, or made 'in the style of' rather than a period studio piece, the market value would likely decrease to the $75-$150 range. To establish full confidence in its attribution, era, and technique, an in-person examination by a qualified glass expert, combined with a search for hidden acid stamps or pontil characteristics, would be necessary.
